A3 upper receiver


Grate deal, keep up the good work!

First impressions of this upper is...


... it looks solid and even shade of hardcoat. Some uppers would show patches of lighter shades if not done correctly. I'm sure it'll function fine but we'll see how it performs over time. Really tight fit on the Stag lower but better than too loose. Don't care for Tmarks since I'll have a scope mount that'll cover most of top rail anyway and rarely removing. Can't beat the price either so I'll give 5 stars for now. Thanks PA

Very good product!!!


Accepted my other parts with ease. Very pleased!!!
