1. Who forges Anvil Arms Lower Receivers and Upper Receivers?

2. Who manufactures Anvil Arms Lower Parts Kit?

i've used 6 of their lowers, so far and all have excellent fit and finish. i've used 1 lpk, in my opinion fair, super gritty trigger and split roll pins, i just prefer coiled roll pins from stag/rock river. i don't know who makes the lpks', lowers or barrels it's a secret for some reason. i can tell you that Jon has very high quality standards and tries his best to maintain excellent customer service, he has a very fast growing company so he's backed up on orders, i feel that his products are worth the wait
