I replaced my bcg to a Gunter nickel boron bcg and the trigger to a Rise 140 drop in. My 300 Blackout is on point and so smooth. I’m ordering another one for my 5.56. Hopefully it will be here before December. I understand due to the pandemic I want everyone to be safe Thank all of you at Optics planet

Bought for a replacement for my wife’s build. Has worked great and the PVD finish is very pretty and she has received several positive comments. Paired with a SHARPS reli-bolt and has proven a good pair.
