Steven V. ★★★★★

The screw holes lined up perfectly with my slide, so installation took less than five minutes. The adapter plate feels machined precisely, giving me confidence it won't shift during use.

Claire ★★★★★

Fits snug on the MOS cut with zero wobble, and the screws were already the right length for my slide. Took maybe five minutes to mount it and the optic sits low enough to co-witness with factory irons.

Carter N. ★★★★★

I was worried about finding the right plate for my MOS setup, but this adapter locked down solid with no wobble at all. The stainless steel screws included are a nice touch.
