nice one....

i've got one of those chinese jobs you get for twenty bucks at the traveling tool sale. it seems fairly accurate. i've noticed that the american made pellets i had lying around wouldnt quite fit. the chinese ones fit fine. might slug the barrel someday and find out how much smaller it actually is.

the thing has a nylon seal around the breech. after a hundred rounds or so, its in pieces. it still shoots pretty hard though. i think the lubricant in the barrel was dieseling. it can do that, you know. gives more velocity obviously but its hard on the gun.

its loads of fun, good for thumping cans, the size and weight are quite different from ak's and sks's but the sight picture is pretty much identical. accurate enough that if you miss, you know its your fault not the guns. keeps your eye sharp when you can't practice with an actual rifle for whatever reason.

they make pistols too. theyre clunky though. some of the co2 revolvers i've seen from other makers dont handle much differently than real ones.

they arent real guns of course, but airguns do have their place.......

What calibre is your Chinese air rifle?

I have heard a lot about them. Also there are numerous articles on changing a Chinese Air Rifle into a fully working gun. It was on Totse so its probably a load of crap as I have never heard of it working and it generally seems impossible.

The guy at the store yesterday informed me that the thing would not be that accurate until it fires off a hundred or so pellets and the seals "settle in".

On the topic of air pistols I dislike the general look about them. I like the ones that look more like real guns, but thats just preference cause I really dont like the goofy ones.

And C02 powered guns will be the topic of my next purchase.

Nice gun, why didn't you go for a .22 though?

And C02 powered guns will be the topic of my next purchase.

I had quite a few C02 pistols, the filth had them all destroyed though, cunts.

Pity about your C02 guns...

Firstly I got a .177 rifle as a training rifle. It can just about take out a Wood pigeon, nothing bigger. Plus .177s are cheaper [Both the rifle and the ammunition]...

I'm not keen on air rifles with scopes. Don't ask me why, I don't know myself... I am a better shot without one.

VCR Bill

On 1st October 2007 a new law commenced in the UK which outlaws the sale of airguns by mail order. Airguns can now only be purchased in the UK from a registered airgun dealer via a face-to-face transaction. To ensure that we comnply with the law, from the 1st October 2007 www.airsportdirect.com will no longer be selling air-rifles, pistols and component parts (including silencers). We will however continue to sell all other accessories, pellets, cases, maintenance products, archery equipment, slingshots and related items.

Please be sure to check with your local Police Firearms Department for the latest UK Airgun Law. It is your responsibility to ensure that your information is correct and up to date.

Pity about AirSport Direct. I hope because of the loss of income they wont close down.

I swear with all these regulations about Air guns we are on the one way road to becoming a full blown nanny state. Not that anyone complies with the regulations anyway...

I have bought a lot of stuff [Not actual weapons just accesories] from the site. They were always fast [In terms of delivery].

You can still get realistic ones on the Internet [Or like a mate of mine] bring them over from the continent, as they are a hell of a lot cheaper there. One good thing about the see through plastic however is the fact you will be able to tell a lot more easily where and how the gun is broken...

check out the career 707 9mm 38cal air rifle
charges to 3000 psi 187 grain slug!!!!! at 747 fps!!!
big game killing power and not considered a gun here. I bought one and the tank to charge it so I would have a qiet shooter. Boy was I mistaking.. This bitch is as loud as a real gun shot.
50 yards punches a hole through a pressure treated 2x6 like butter and makes dime size hole going in and half dollar size comming out. They even have a 77 calibre made by barnes that has as much kinetic energy as a 12 ga slug 2 3/4"

Shoots pretty well; as well as I'd ever need. The shotgun is really just for kicks (geddit?). It was dirt cheap and it's a bit of a laugh exploding water bottles with it. I don't use it for anything more serious.

It's the rifle I love. It's a scaled down M1 so it's absolutely beautiful. Speaking of which, I should be bringing it out shootin' soon, now that I have sone time off. :)

What guage is the shotgun and how old is it?

I don't know what gauge it is; like I said, I don't care much for the shotgun. It was made in the USSR though, and that hasn't existed in almost 20 years.

Interestingly, the rifle was made in Czechoslovakia, and that hasn't existed in almost 20 years either.

My 2 cents from a certified gun nut. bruno's as I call em are fine rifles. The czech's make a very good quality weapon not alot of frills but serious on accuracy

second on brnos being good. can you get cb caps there? try one without hearing protection and you will know why i mentioned it. not super powerful but certainly nothing you want to be on the wrong end of.

make darn sure you know what your shotty eats before you fire it. not just gauge but chamber length. given that its older and russian, you probably cant feed it steel shot without damage.

duck is tasty.

@ thor. my chinese air rifle is a .177. as to the totse article, you do remember what they say about broken clocks, dont you? well, i'm not an expert, but for the most part, it seemed plausible. the part where he said the .22 airgun barrel is smaller than the .22 rifle barrel is cause for concern. you don't want bullets stuck halfway down it. getting the position of the firing pin right would be very tricky. you are more likely to just break your air rifle. from the pictures and descriptions, the basic design of both our rifles are very different from the one in the article anyway. its an interesting idea to play with though.

high power air rifles... i've heard of quackenbush, but not career......

I know dennis Hes made me 2 quackenbush big bores I have traded away. Long wait for his work though. my career by the way is 9mm not .45 cal I supose that is about 38 caliber give or take. It shoots heavy bullets best. It's ok its made in korea costed $450.00 very powerful
the sam yang big bore 50 is the one i would like to get. airgun from hel lol

where is the conversion thread? I was looking at one of my side cock china springers and conversion looks like it could be done with a blueprint of sorts. think i would mic the bbl and shoot cb caps in its shorts or very low power subsonic Lr

Iceman, it was an article on Totse.

Not a thread. I havent visited the forum in many years...

For reference here is the article in question.

You might have seen in news photographs of African riots--often you can see someone brandishing what appears to be an air rifle. You eyes do not deceive you, it may very well be an air rifle--but it has very likely also been converted to allow firing single-shot 22LR shells, and is not loaded with a pellet!

There exists a method used in poorer African and Asian countries for many years, of converting a cheap 22-caliber airgun to function as a single-shot 22LR rifle. This document does not attempt to give exact instructions because the concept is pretty simple to understand once you have a suitable air rifle in-hand, but rather is just a general run-down of the method.

You need a specific type of airgun for this--just any type will not work. I saw this years ago (sometime in the mid-1990's) in a print magazine about African poachers using converted airguns that were made in India--but at that time, I didn't think much of it because the only similar types of airguns I could easily obtain in the US were expensive European made types, too expensive to be practical to attempt to convert. As of this writing (2004) there is now a huge supply of Chinese-made airguns available (in the US), and some of these are basically identical to the types suitable for conversion this way.

The type you need is a side-cocking spring-piston rifle, with a fixed barrel and a retracting chamber--but the chamber has to be concentric with the bore. As an "example" of what to look for, search for photos of an RWS/Diana Model 52 airgun--this is an expensive European-made air rifle, but it is the general type you need to find to convert. There is a model of Chinese-made airgun that is basically identical in function, if not quite in looks, to the RWS Model 52. The Chinese guns made this way are inexpensive yet constructed very solid--steel action parts, usually in a wooden stock. Totally unlike the inexpensive US-made airguns sold in department stores.

The way you convert the airgun is you ream out a chamber in the breech of the barrel to allow inserting a 22LR shell in it, then you drill a small hole slightly off-center in the piston face, and tap a piece of a nail into the piston and file the nail down so that when the piston reaches the end of the cylinder, the nail sticks out through the air-transfer port in the cylinder and strikes the rim of the 22LR shell and ignites it. That's all there is to it--you don't need to modify anything else on the airgun. The reason other types of spring piston airguns aren't suitable is that the pistons often rotate during use, and the air-transfer ports are drilled off-center, and so there's no way to make certain that the firing pin will always line up and stick out through the air transfer port. Most all "barrel-cocking" air rifle for instance cannot be used because of this reason--the barrel and air-transfer port are not concentric with the piston cylinder.
There are a few technical problems you may have to find ways to deal with, that I will explain here:

First is that in the few examples of these airguns I have seen, the barrel was press-fit into the forend of the receiver and couldn't easily be removed--so you may have to find a way to grind out the chamber while the barrel is still attached to the rest of the gun. One method that has been used successfully is to insert a piece of metal rod a couple inches longer than the barrel and nearly as big as the bore, glue a piece of sandpaper around the breech-end if it with instant-drying cyanoacrylate glue, and then attach a drill to the muzzle end of the rod (left sticking out) and pull on the drill, pulling the rod a short way into the barrel while running the drill. You also need to cut a small groove for the rim of the shell, but that can be done easiest with an electric engraver by hand, from the breech end. The rim groove doesn't need to be perfect; the gun will probably not seal perfectly anyway so you will see some gas escape from the breech--but the breech is set far forward of your face, so the danger is minimized.

The other problem you might have is that you may have to disassemble the gun to drill a hole in the piston. You can try drilling a hole off-center through the air-transfer port without disassembling the gun, but you will need a right-angle attachment for the drill that is small enough, and a drill bit that is short enough, to be used through the gun's loading port, and the piston may catch on the drill bit and only spin inside the cylinder. This is because many spring-piston airguns use pistons that are "floating", in that they are made to allow rotation inside the cylinder. There is a technical reason for this, but it's not important here.

The "sub-problem" with disassembling the airgun is that the wire-coil spring inside is already compressed quite a lot just to get the airgun to fit together. The spring may be pressed into a space only 8-10 inches long, yet may be 24 or more inches long when it is removed from the gun.

You can probably get the airgun apart without any special tools but you will probably not be able to get it back together without them. And even taking it apart without using a spring-compressor is risky, because when you take out the last bolt, that spring will FLY out at high-velocity, throwing various parts with it. To put airgun springs back in (as well as take airguns apart safely) airgun enthusiasts make tools generally called "spring compressors". There are plans online for various types of these that you can make pretty easily, so I won't go into them here except to say that all they are is some type of clamping/guide system to allow you to cram a strong two-foot spring down into a one-foot space, using only your own two hands.

One concern you might have about drilling out the chamber using a steel rod passed "through the barrel" is that you will ruin the barrel. This isn't really a concern, because you won't rub off all the rifling from inside the barrel, and a 22-caliber airgun bore is generally a bit smaller than a 22LR firearm bore anyway. Reaming the entire airgun bore out a bit would actually help lower pressures and improve bullet velocity.

Second part...

The only calibers that are really worth considering are those that might be fired from a airgun-sized bore. Airguns typically come in .177, .20, .22 and .25 calibers, but I have only seen the inexpensive Chinese airguns suitable in .177 and .22 calibers. 22LR is the closest caliber that will require the least amount of grinding to create a chamber.

22WMR uses a case diameter that is slightly larger than 22LR, so that "22-mag" cases can't be accidentally loaded partly into a 22LR chamber at all. I suspect the airgun barrel would hold up to firing 22-mags, but you would have to do quite a bit more reaming to get the cases to chamber and along the entire length of the barrel. And such a gun wouldn't work well with 22LR bullets anymore, due to gas blow-by in the larger-bore barrel.

There also exist now two newer .17 rimfire calibers, and you might be wondering if these could possibly be used with a .177-caliber airgun. The answer is yes and no--yes because you COULD rig up a (solidly-built) 177-caliber airgun to fire such shells and the bullets would certainly come out, but no because it wouldn't work well. First of all, it would be a lot of grinding to cut the chamber, because (unlike the 22-caliber rimfires) the chamber size is a lot larger than the bore size. The second reason it wouldn't work well is because the 17-caliber bullets are quite a bit undersized--the bullets are .17 caliber, and the airgun bores are .177 caliber. You can take a .17-caliber loose bullet and stick it in a .177 airgun barrel and tilt the barrel down, and the bullet will slide right on through and fall out. If you shake the airgun with the .17 bullet loaded, you can hear the bullet rattling inside the barrel.

Is all this safe? Yes -- the airguns used are built very generously of solid steel. The barrel is often as thick as a regular firearm barrel would be, and then the breech end of the barrel is set into a metal block, reinforcing the breech end even further. And finally, the shell is set way ahead of your face--unlike with a conventional bolt-action firearm. If you inspect some cheap zinc pocket pistols, you will see that they are SOLD as firearms, yet are built using a weak zinc frame surrounding a much-thinner steel barrel tube.

After the airgun is converted, it is still fully-capable of firing regular airgun pellets the usual way. And surprisingly enough, this whole concept is not new--back roughly 100+ years ago, combination guns/airguns were commonly sold that were based on this very same concept: spring-piston airguns using a firing pin on the piston face to allow firing rimfire ammo. Many were even constructed small in "children's" sizes, and intended to fire 22-short ammo for outdoor use as well as pellets for indoor use.

I didnt write the article. It was written by a Totsean by the name of Bullwinkle8357 aka -fini-... I doubt there the same person though as it only makes sense to have the same handle...

Heres the link anyways: http://www.totse.com/en/bad_ideas/guns_and_weapons/convertanairri179178.html

think i would mic the bbl and shoot cb caps in its shorts or very low power subsonic Lr


the idea is you drive a soft lead slug down the barrel and then use your micrometer or vernier calipers to take measurements off of it. further, cb's and shorts would be more likely to lodge in an undersized barrel in my opinion. i'd check carefully after every shot until i was sure this wouldnt be a problem. (open action and drop a cleaning rod down the barrel, don't look) other problems would likely come from a pierced case (from the firing pin being too sharp or too long) or a split case (too much metal removed in chamber area, breech opening up too quickly)

basically, the piston acts like the bolt in a straight blowback .22. it holds the cartridge case in place against the pressure of the expanding gas by virtue of the force of the spring and its mass. the mass is the factor that makes the biggest difference.

is the mass of the piston significantly less than the mass of a standard semiauto .22 bolt or slide? if so, maybe you'd get split cases and a lot of gas coming back at you even if you cut the chamber right.

there isnt much gas involved, and the chamber pressures are lower than for many other rounds, but it still may be enough to cause you a lot of grief.

Fires wonderfully.

Three shots completely destroyed a tin can but tomorrow I will get to work on proper accuracy training with some paper targets I got with the gun...

As for the 100 shots and under wont be accurate I guess the guy in the shop might be slightly wrong...

fire it off some sandbags or something so you know how tightly the rifle can group. then fire offhand, prone, or whatever and see how tightly YOU can group.

remember, the weight of the rifle should be supported by your bones, not your muscles. watch your breathing, focus on the front sight. pull trigger slowly.
