Bought a Silencerco lower to build out. Seemed to have all the features I wanted. Abmi bolt release. Beveled magwell. 7075-T6 billet construction. Seemed great on paper, and looked really nice in person. So I buy it and proceed to try to install a FCG. Drop in trigger and milspec LPK. To my surprise, the trigger pins and ambi safety were both sticking out like a MM too long. I take out my calipers and measure this lower's body at the trigger and another lower I already built, and sure enough this one is definitely thinner.
Having only made one previous build, I've never experienced this before. Is this common? What are the work-arounds? I suppose the trigger pins don't really matter as long as they stay in place, but the play on the safety is concerning. Once I put the safety selector detent in, it balances in the middle somewhere, but seems to have like a half MM space on each side before the lower body. My concern is that if it were impacted right there with enough force to defeat the selector detent, I could lose proper functionality of the selector. Maybe a rubber gasket or washer? Also noticed the Magpul MOE+ factory grip screw wasn't catching threads even when tightly pressed up into the lower. Even did a test run without the detent springs just to see. Nope. Had to buy a longer grip screw. Is this lower completely out of milspec?
Anyway, disappointing (through no fault of the seller though).
