I have an AR 15 build with a lot of quality parts. Yes it is a PSA stripped lower. It has a polished mil spec trigger that was polished and lightened. KNS trigger pins. Extended mag release. H1 buffer. Tool Craft NIB bolt carrier and charging handle with badger latch. The upper is a Bkings factory built. BA 11.5 barrel. Parallax tactical 11.75 Mlok handguard. Kak blast can.The bolt carrier was factory head spaced. Sba4 brace. It has only saw about 150 rounds and functions flawlessly. I just prefer my 14.5. I am willing to sell as is or keep my optic and BUIS for 200 off the listed price. Light not included but can leave mount.
