ARAK 21 is sold The lower is a Santan Tactical ambi AR-15 billet lower, I used a DMPS lower parts kit and a Rainier Arms mil spec AR-15 buffer tube kit, came with spring and buffer. The grip is an Ergo. It's in mint. Really looking for cash, would trade for Glock 17 Gen 4, complete pistol or just the frame +-$ $400 for the lower. Im on the east side. All local laws apply. I will cover transfer fee if transfered at Rehv Arms in Maple Valley. Pm if interested.
