This is an excellent upper. Everything fits the way it should and finish matches perfectly with the SP223 Gen2 lower. It has sexy lines and looks perfect for my build. I highly recommend this upper!

Roll pins are the bane of my existence. I've never yet been able to install or remove one without either injuring myself or, worse, scratching the finish on a receiver. Seekins Precision uses tiny hex screws on their billet receivers instead, a decision which earns my eternal gratitude.

Flawless machining. The fit between this upper and the Seekins SP223 lower is perfect. First time ordering from Bauer Precision and this won't be my last. Fast processing and shipping!

Product was what you'd expect from Seekins Precision. Anything from them is pretty much good to go. The real MVP of the transaction came from Bauer Precision themselves. Shipping was fast and customer service was excellent. I left a note on the shipping/comments section of my purchase order and they called the next day to inquire about it. Which was very impressive. 10/10 will do business again.

I was a bit skeptical that I would receive my order after having two other major online resellers show "in stock" receivers and then cancel my orders. One of them took a week to refund me. After seeing this posted as "in stock" on one of the major AR forums I quickly came here and ordered. I placed a call to confirm and was surprised that the owner actually took the call, assured me it was in stock, and that I would receive my tracking shortly. A couple hours later I had a tracking number and free shipping. Plus about 20 minutes of free build advice. How's that for service! BTW, this receiver is awesome! Completely blemish free and solid! Looks great on my current project!
