    AR 15 Lower Build Kit

    Posted by Tom Griffith on Oct 25th 2020

    I must admit that compared to a similar kit from another manufacturer, installed in a receiver that is only ONE digit away from the serial number of the on in this "build," I had an extremely hard time with installing the trigger-disconnector assembly, and a fairly hard time with the trigger guard and bolt catch. It took about 5 minutes with my other build kit to do the trigger - and I'm not kidding - it took about two HOURS with this kit. It seems that the Disconnector Spring in this kit was about twice as "strong" as the previous one I'd installed. As far as the Bolt Latch and the rear part of the Trigger Guard were extra hard because the roll-pins seemed several thousandths of an inch larger than those that I'd used on the previous build. Maybe I've "lost my touch." I do NOT know! In finishing, I have not had a chance to take it to the shooting range to check it out, but the completed lower DID fit and function well with my new upper, when dry-fired, etc.
