has anyone tried the crank fire trigger on there ar.

Not trying to be a dickhead, but..................why?
Its just a gimmick to waste ammo and make noise.
My ammo and time are to valuable to just waste. I'd rather spend the time and ammo bettering my shooting.
But, if that's your cup-o-tea, carry on.

Hook it to a cordless drill, then place a pressure pad to the drill on the grip.

Then prepare your anus.

Seems legit.

What could possibly go wrong?

Absolutely nothin... Lol

Great way to cause an out of battery discharge.......no thanks.....

Just stick a cake mixer inside the trigger guard and plug it up and run.

Locomotive traction wheel.

Go big or go home.

Please explain to us how this is possible.

I am not following you. Please explain.

I don't remember askin' you a god damn thing.

Now, does Marcellus Wallace look like a bitch?

ATF '13er troll account?

Ya think?

your better off with either a slide fire or a really fast trigger finger

 

Not much of an ATF troll if he's asking about legal devices used in legal ways.

I just bend a paper clip and throw it in my receiver.  Or tie a shoelace on it.  That makes it go F/A for sure!

hello Mr ATF agent..

I've used one before, seems easier to use than the hellfire trigger device, it just clamps onto the trigger guard. I thought it was fun in my 10/22, its a good way to blow through a brick of ammo, I don't know if I would dare put it on an AR with ammo being expensive as it is lol.
For $20 its cheap fun.

Everyone knows you have to file down the firing pin first.  Geesh....I guess some people are okay with passing on bad and/or partial information.  

I like to attach mine to a belt fed shrike upper and a bicycle on a stand...

Just bumpfire it.

Why put the bicycle on a stand? You could be mobile bro!

i have got  good info here. with my first build... but seance then i see we got a few morons  here now

Go back to the tech forums if you want to ask serious questions about goofy gadgets. Or stay in GD and you will get goofy answers to serious goofy gadgets.

Agent no, slave to ATF logbooks.. Yes...

Modify one of these:



To work with the crank, a 9v battery and a small electric motor, combined with the JP yellow springs.

Lulz, someone has no clue how an AR actually works.

You're right.......mount it up and crank away.....

Articulate how the firing pin can protrude from the bolt face when the firing pin stop shelf on the bolt carrier is behind the rear surface of the bolt the required distance for the cam pin to have rotated the bolt out of the locked position.

Didn't follow any of that? That's okay, I can post pictures if required.


You're talking about something you do not understand and further, are wrong about. Don't post falsehoods and I won't point it out.


ETA: Pics demonstrating. For those who want to follow along at home, pull out your ARs bolt carrier group... For the 1% of GD that actually owns an AR, that is.

In all of these pics, the firing pin is being pushed as far forward (up, from the cameras perspective) as possible.

First pic, bolt in the "fully locked" position. Note the firing pin protruding from the bolt face. Unseen is the fact that the rear tail of the bolt is protruding from the firing pin stop shelf on the bolt carrier. In this photo, the firing pin is bottomed out on the tail of the bolt itself.



Second pic... Bolt has been pulled forward slightly, just as if the bolt carrier were slightly rearward in an AR. Note that the bolt is still in a LOCKED state. Where's the firing pin? Well, a result of the bolt going forward/carrier going reward is that the firing pin stop shelf is now further to the rear than the tail of the bolt. The firing pin is now bottomed out on this part of the bolt carrier, NOT the bolt. Unlocking of the bolt can only take place after this has occurred, such that the firing pin can no longer protrude from the bolt face. Rotation of the bolt by the cam pin begins basically immediately after firing pin retraction from the bolt.



In the last photo, you can see the bolt in its fully unlocked state. The firing pin is far away from the bolt face.



Obviously, when the bolt goes from unlocked to locked, the same thing happens in reverse. Bolt unlocked = Firing pin cannot contact primer, period.
