Want to cut a half second off of your bolt-lock reload time on an AR15/M4? Install a Magpul B.A.D. Lever. and you're half way there. Whether you love it or you're on the fence, no one will deny the Magpul Battery Assist Device (B.A.D.) will significantly decrease your bolt-lock reload times.

Want to cut your double-feed clearance times in half? Installing the Magpul B.A.D. Lever allows you to keep your hand on your firing grip while locking the bolt back to clear your malfunction. On top of that, you can now administratively unload and lock your AR15/M4 action open with ease- simply drop your magazine, then press upwards on the B.A.D. as you manipulate the charging handle to the rear with your support hand.

    Almost a necessary upgrade to any AR-15

    A great upgrade to any AR-15, almost a necessity at this point. Really wish manufacturers would just have these installed from the get-go.

    Very sturdy quality, have yet to run it on my personal rifle but I have used them on other peoples. The order was shipped out very fast and no complaints about SKD turn around time.

    bolts on in a minute or less. u need to take the time to train with this product or dont buy it. once u get aclimated to the lever and its operation - u can become very fast at reloading

    2 min. install! Works as advertised and beyond! This aides in shaving that extra split second off chambering a round and getting back on target.Sturdy, threw a 100 rounds through it the other day and it's still as snug as the day I installed it and works perfectly. Great buy, a must have for any AR platform.

    This makes me way faster with my rifle. I wound up buying two-one for my home rifle and one for my work gun.

    Great upgrade

    Very easy to install, works like a charm. Allows clearing a jam without changing your firing grip and without an expensive upper receiver with a proprietary ambidextrous bolt release/catch. Pretty much essential for right-hand shooters.
