Really nice little receiver. Has a keyhole forge Mark. Came in a sealed milspec plastic bag. Noticeably better quality and heavier than cheap lowers like Palmetto That I had laying around to compare it to.

Amazing Lower Receiver

by -

Purchased this stripped lower to match my FN Barrel and upper. Extremely well coated, it resisted a few scuff marks that I accidentally made when installing the parts kit with Zero blemishes. All dimensions are perfectly drilled and cut for all the fittings to be placed correctly. None of the coating chipped when installing the pins. This is an amazing lower receiver to use when you want to build a reliable AR-15. Works great with any lower parts kit.
