Magpul BAD

Magpul have developed a device called the B.A.D (Battery Assist Device) which allows quick bolt release on an AR-15 using just the trigger finger – no more fumbling around to find the bolt release.

The BAD attaches to the bolt release button. Its lever extends through the trigger guard which allows the bolt to be released with only the trigger finger .


Incidently, Magpul designed the Remington ACR / Magpul Masada rifle so that the bolt could be released with the trigger finger.

The price on the Magpul website is $29.95.

    I have two of these on my rifle, one of the best and most inexpensive upgrades I've done. Installs in a minute literally, very easy to control battery. Main thing it speeds up is the double feed malfunction. I think I read somewhere it shortens down the number of manual of arms steps from 17 to about 11 for double feed. Regular reloads are sped up slightly. Speeds up even more if you have a Redi-Mag

    Hightly recommended mod, good luck finding them in stock tho
