Missing parts

My package was missing the lever

Will it fit?

I have two different manufacturers of uppers. The device fits on the bolt catch, but was too thick. It made the bolt catch inoperable on both platforms. Before purchase, make sure that it will fit your receiver and operate. Returned mine. Wish it would work, but not "universal" fit.

Don't buy

Upon installation the blue loctite they put on stripped the threads on the back piece that the screw goes into. They should send a small amount to put on wet and let dry after installed.

fit issues

I tried one and it would not fit properly on Aero Precision upper and DPMS lower combination, with High Standard bolt release. This was purchased by me and not a gift.
