Upper assembly
These guys are absolutely great. Sent in a Faxon 16in gunner barrel for FSB pinning and also an assembly of upper receiver received it back in less than 2 weeks. Everything was perfectly aligned and done not a single scratch on the parts at all. You can definitely tell they take great pride in their work and craftsmanship. Thank you TNTE

Flawless operation
The upper was built with an 11.5 inch barrel and worked flawlessly. The initial magazine was problematic. After cycling the action a couple of dozen times by hand the bolt worked itself in. After the barrel was broken in the next 500 rounds worked perfectly. No stoppages or hiccups. We used 4 different type mags with no problems. I an very happy with the build.
