Lower Parts Kit
Excellent! Nothing missing. All parts were top quality with perfect fit and finish.
USGreat complete kit
Came with absolutely everything including two extra detent springs, fit perfectly into an BCA Lower
USNo MIM parts
Have purchased several of these lower parts kits because of the quality and especially because all the parts are machined, not Metal Injection Molded (MIM). They have for my lowers like a glove and function even better. Nothing wrong with MIM parts, but for longevity I prefer Machined parts.
USLower parts Kit
Perfect fit and function. Great price!
USBetter than mil spec
My parts kit contained everything needed. On outside of the bag, it stated made in Taiwan. The parts feel very durable, with a heavy coating. All parts fit well, not too tight, and not any slop. Trigger was better than mil spec, all parts fit without issue. Would order again!
