Looking forward to completing my build. This upper was done right. From the properly staked gas key on the bolt carrier to the perfectly pinned A2 front post. No blemishes or tool makes to speak of. Very happy with the product.

Couldn't pass this deal up. Delton makes a very good product and at the sale price I got from Primary Arms, I couldn't pass on it. Complete, with BCG and CH. Thanks PA for another great deal and fast shipping.
