Clay, I just finished putting one (actually 4, but you asked about an A2) together myself. Anderson receiver, a Heavy Bbl, 20", Del-Ton upper that the LGS made me a deal on, the rest of the hardware is PSA, it easily is a 2" rifle.

The bottom 3, are PSA uppers, complete with BCG, and they were 'BLEMS'
Everything I buy from PSA is a 'blem'......... So far, I'm not sure that I can find the 'blemish'..............
