CMC LPK
This is the 1st time buying a CMC LPK. I love their triggers and now, I really like the lpk they make. Checked all the items very good and they are made very well. I will for sure buy more of these kits in the future. Tim
USGREAT KIT TO HAVE
This is a super spare part kit to toss in your range bag and one for the bench. I purchased two and will get more when they are back in stock. Great price, handy, and convenient. I'll probably snag one or two for a friend as well, they are cheap enough and so is he, lol. Arrived quickly, great customer service from AR15DISCOUNTS.
