Praxis: Testing the Bumpski on an AK & PSL

Meet the Bumpski. Today I had a chance to test fire this street legal bump firing mechanism on both an AK47 semi-auto in 7.62x39 and a PSL in 7.62x54R. Here is a link for the video below.
Now I am on record as an advocate of long-range semi-auto aimed fire. Still, there is a role for suppressive fire -- when facing an enemy that is numerous or subject to the psychology of being on the receiving end of aimed, full auto fire -- however Class III weapons are out of the price range of most folks and the licensing restrictions are onerous, to say the least. I have friends who like to piss away ammo bump firing their AKs by hand, but the problem is that this is usually from the hip and hardly accurate even at fifty meters. It is suitable for fighting a Chinese People's Liberation Army human wave assault in an alley I suppose, but not much else.
Now the folks at Bumpski have come up with a stout and reliable aluminum bump firing mechanism which uses no springs (which would make it illegal) yet with a little practice is quite controllable from the shoulder. Here is a review with a bit of technical explanation.
The device is heavy, being of solid aluminum, yet this aids in control. It is difficult to retrain your reflexes to use the Bumpski, but a little practice teaches you to put gentle forward pressure on the front hand guard (a vertical grip helps in this, although we were able to make it work easily with standard hand guards).
Semi shots are still available by using the trigger without the Bumpski device, although it does get in the way somewhat. Again, a matter of training should solve most problems.
The cyclic rate of the AK we tried compared favorably with a standard full-auto AK, and the PSL worked like a BAR on slow-rate. Unfortunately we did not have a Saiga shotgun to try the device on.
The biggest drawback is that the Bumpski costs as much as an AK to mount it on, but even so, the factory is selling out of them as fast as they are made.
As an add-on attachment to a firearm, there is no requirement for purchasing through an FFL, and I'm sure the hoplophobes will begin screaming very soon. Get them while they're hot, as they say.

It would be interesting to see a comparison to the Slide Fire. One would, I suppose, expect greater durability from the Bumpski, given the aluminum construction.

Sorry .... but if I want to spend another $500 bucks on something I will buy another firearm to give to a neighbor in the defense of my family or AO. Yes .... it would be nice, but I have just found out I am going to be a grandpa for the first time. Priorities dictate that I make any available cash into essentials and food.

I have no spare ammunition to waste on full auto anyway. There was a time when I would have bought this and burned up a few hundred rounds with it having fun..... those days are gone I fear.

The other company, slide fire solutions, makes oen for ~$300 for the AK and AR.

I have tried the one for the AR. It is tons of fun, but would never go on my SHTF AR15. No point in shooting up all your ammo.

Now on a .22lr or 9mm AR15, there is a lot of fun and cheap range time there.

For those that can afford it, I say go or it! But having experienced full auto in combat, I'm a strong supporter of accurate semi-auto fire. When the "Chinese People's Liberation Army" comes down the alley and I see a need for full auto, I'll just have to shoot someone carrying one and re-arm. With this Bumpski, I foresee the POTENTIAL for Bob Stewart type of event. I don't want or need any crap until the time comes we are in the alley.

Automatic fire turns money into noise.

Get one now. I have no doubt those "really good guys" at ATF will soon make a finding about these stocks, and magically reinterpret the NFA and their own previous rulings.

It will happen, be prepared.

Bump fire toys are a solution to a problem that does not exist. Ammo is better used to practice and retain proficiency in ACCURATE semi-auto fire.

People can spend all the money they want to on toys, but don't confuse toys with things that are of practical use in the field.

I have seen many people that can squeeze the trigger almost as fast as the action can reset, some faster, usually with greater accuracy than the real machinegun.
So buy one of those hand exerciser units rock climbers use and save a few bucks.

WE WANTED TO SEE VID OF **YOU** SHOOTING THIS!!

WE WAS **ROBBED**!!

Mixed feelings about the ATF thing...

They did approve it, but then they once approved the AA too...

This one's going to be a sticky-wicket for them...

In reality, the LEFT hand becomes the "trigger" on this device - you push it forward and...

Think if the "standard" trigger was completely enclosed, with a trigger-bar sticking in where the finger would go. - it will fire so long as you continue to push forward with the left hand, one shot per "trigger **PUSH**".

I really can't see how they can ban this without overturning their "shoestring" decision, as they're based on the same principles.

In the latter, the string becomes the trigger, and the weapon fires multiple shots per trigger pull -- thus being a MG per the BATFEces.

In this case, it only fires once per trigger PUSH - and they really can't have it both ways!

Still not crazy about this, though I DO see its utility for even real world" use in the hands of someone with the finances to afford the ammo to get good with it...

I once got suckered into buying a little device... In short, it would actuate the trigger when you pushed FORWARD with your trigger-finger.

By "fluttering" your finger - back-forward-back-forward - you could achieve near full-auto fire.

The only thing that made said device land in the "rip-off" category was the construction. It just wasn't sturdy enough to do what it was supposed to do with any regularity. Damn shame as it had a lot of potential...

As it is, I can fire my weapons - CONTROLLABLY - with surprising speed and accuracy.

As Dakota said, if I had $500 to throw at firearms, I'd add 2 SKS rifles and a tin of ammo to my stores...

Could you make your own out of wood, using a drawer slide between the parts? Assuming you had a need for one but not the money

Does anyone know if there is any such device available for a Cobray M11 9mm?
