Simulated "Full-Auto" Trigger Devices

I know that these devices (Hell Fire, etc.) for use on semi-auto rifles generally have a poor reputation, but it seems like new types keep coming out, so I though I'd ask and see if anyone has found one that works okay. I've heard that one type that uses a little finger crank to pull the trigger rapidly works reliably, but this seems like an awkward and unsatisfying setup. I think most of the others rely on achieving a balance so that recoil barely resets the trigger, and the steady pressure fires the gun again. I think there are also some that fire on pull and again on release (to give a high rate of fire).

I have a paintball gun with an add-on trigger that has a small piston mounted behind the trigger. Each time the trigger is pulled, a small amount of CO2 is bled off to this piston to push the trigger back out. This works great to achieve a full-auto effect - you just squeeze steadily on the trigger and it bounces rapidly under your finger firing very rapidly and effortlessly. It has a small dial to set the amount of gas bled off and control the speed of fire. Also, you can still fire semi-auto if you are careful to release pressure on the trigger when the gun fires (or if you turn down the gas control). Something like this would be nice on a real firearm, although I don't know if it would be legal (it might be, because the trigger does move back and forth for each shot, and finger pressure pulls it). Of course, it would have to have a small CO2 cartridge or something to power the trigger.

I have also tried (with some limited success) the "bump method" by which you hold your trigger finger steady and pull the rifle forward so that (if everything works perfectly) the gun fires, recoil resets the trigger, it fires again, and so forth for a full-auto effect. This doesn't work predictably enough to be much fun for me, and of course, you can't really even try to aim.

Anyway, what are your experiences with these devices? Anyone find one that works? The videos they show at gun shows allways make them look like a lot of fun. By the way, I'm not really looking at this for anything more than fun - I doubt I would want to use any of these for self-defense for a variety of practical and legal reasons.

Well of all the ones I tried the GAT was the best because it allowes you to aim the weapon the best.
Bump fire take some practice to make it work well, and some weapons just do it better then others.
I can bump fire my SAR-2 from the bench.............but thats the only weapon I can do that with.
I replaced my hell fire with a rubberband, then replaced the rubber band with the bump. On certain weapons I still use the rubberband to inhance the action. I don't bump much anymore as it really doesn't do much but waste ammo. Came to the conclusion that if you want to fire on FA then you should just save up your money and buy a FA.
GAT, Hell Fire, TAC TRIGGER, rubber Band, Bump...........there are several others that I can't remember the names of, little springs or pieces of rubber behind the trigger............all too expensive.
good luck

Devices like this remind me of a guy's comment about cocaine: "It's God's way of saying you have too much money."

Art,

I like your quote, but my wife would say the same about most of my guns and other toys. Does $30 or so really sound like a lot for a device you could hang on the trigger guard of an AK/AR/SKS or whatever and legally fire the thing full-auto? Sounds like pretty cheap entertainment to me (I think the cost of the device would be very quickly overshadowed by the cost of ammo). That said, it is a lot of money if the things don't work (which I gather is common).

As for just getting the required license and buying a legal full-auto weapon - that's probably impossible where I live, and even if it were possible, I don't want it THAT bad (I can think of a lot of other things I'd rather spend the money on).

But, when I walk by those videos at the gun shows and see guys happily blasting away with their legal "almost machine guns" - I always pause and ponder. $30 or so seems pretty cheap if I thought the things would work as advertised. :)

Fella in Santa Ana, Kali, 'bout 20 (?) years ago gave the PD fits with one of the crank jobs. Hooked it up to a cordless drill, had the rig mounted on an American 180.

Lots of ammo before you run dry, even if it is 'only' .22LR.
 
C.R. Sam,

Who cares? :)

As I said, this would be just for fun. It would be nice to be able to shoot from the shoulder and aim (rather than from the hip, as is typcial using the "bump method"), but accuracy is a secondary consideration with these. Maybe this all sounds silly to someone who was in the military or has otherwise had the opportunity to shoot full-auto, but the closest I've come is a paintball gun and an occassional unplanned burst from an old .22 I had. I'd just like to see how it feels to really spray some bullets downrange. Assuming anyone recommends a good one, I'd probably just put it on every year or so for a magazine or two - just to "show off" and have some fun (safely, of course).

I've got to admit that the trigger on my paintball gun got me thinking about these again - it's a hoot to just pull back on the trigger and let the paintballs fly. I'd like to experience the same thing with a "real" gun. Maybe I'll just have to go to Nevada and try it at one of the places that rents sub-machineguns.

DougB, "...too much money." wuz referring to the ammo, more than the device. :D

Turning money into noise isn't really my bag; I like to see hits, and the results thereof.

Yea I tried that hellfire trigger thing on my 10/22, very non-conducive to marksmanship and an unreliable POS.

I've got a device for the Mini-14's that fire on pull, fire on release. It came with an ATF letter that said it is legal cause it only sends one round down the bbl with a single function of the trigger. Pulling the trigger is a single function and releasing the trigger is a single function. Its 100% reliable and is internally installed, so it still allows you proper hold techniques which are conducive to marksmanship. I figure that if you forget that second round is coming, its still a ND. I've not forgot so far.

I think it'd be good in a firefight. the two shot "burst" would conserve ammo somewhat and it can be speeded up to deliver lots of grief quickly, if need be. Its not a true FA type rate, buts it is mighty quick.

I bought a dozen cinder blocks and stacked em' up to put a magfull through em', big cloud of dust, lots of fun! Would've made a great video.
 
that electric drill gambit is dicey at best

what you are doing is making one trigger pull of the drill actuate the rotary

thats a machine gun

the GAT would be kinda fun with a beta c mag with the AR on a pintle mount

i think a foreward Knight grip on a 22lr AR with the GAT would be quite a targetable anti tin can machine
