Don't forget a .308 mag release button

by -

The kit is good and works. Except the mag release button.
The mag release button is for a AR-15, it's too short. You have to use a tool to fully press the button in enough to start the threads, if you screw it in too far the mag does not release. Too little (one rotation) the button rattles and after one mag the threads striped and the assembly popped out.

great kit

by -

Received the kit and everything looked right with no missing parts. Install was uneventful like any other LPK install. Magazine catch / button was the correct one and works fine.

Mag Release Out of Tolerance

by -

Mag release was too thin for a standard pmag. Caused feeding issues. Changed it out for a Luth-AR release and now it cycles.

The mag catch and safety work fine. Generally displeased.

It was good to speak to you on this issue and get you taken care of.
