View Full Version : Add-on 3 shot burst device for AR

Have Googled & can't find any. My friend saw one that also somehow causes full auto[?] but didn't buy- now wishes he did.

Any ideas?

You probably want to ask the guys over at the NFA forum (http://thefiringline.com/forums/forumdisplay.php?f=4).

More than one shot per trigger pull makes a machinegun.

I probably poorly worded my post. What my friend saw was a legal device.

I know there used to be a little crank device that would attach to the trigger guard. Good way to waste a lot of ammo.

there was also a device I've seen at a gun show a few years back that essentially helps you bump fire the gun. Claimed it was 100% legal. Didn't care too much either way, it's a waste of ammo.

Maybe your friend was talking about a Lightning Link.

The crank is legal

The hell fire is the "bump fire" one http://www.ak-47.net/products/hellfire.html it's legal

The lighting link is only for AR's and is an NFA item (around $7500 + $200 stamp and 6 month wait)

Beyond that there are a lot of ways to get into trouble. There have been a few that were initially approved by the BATFE, AW-SIM and Akins Accelerator come to mind first but when it turned out that they worked as advertised the approval was rescinded.

This should give you a good idea of the quality of the products that remain legal.
