    I ordered the barrel minus the BCG and am very happy with my purchase. Is the BCG offered with this barrel phosphate or nitride coated?

    I added an Sig Sauer Romeo 4B red dot sight and YHM BUIS. Very light and handy. Right now, sitting atop a S&W M&P lower. Love it.

    • That is great to hear, we are glad we could help out with the build.

  15. 5 out of 5

    What length gas system?

    • this is carbine gas set up

  16. 5 out of 5

    I bought this upper and want to put a 15 ” free float quad rail on it. Would I need a different gas block? What all would I need to have?

  17. 5 out of 5

    I assembled my rifle using this upper, your Gen2 lower parts kit and 6 position stock set and it all went together great. I’m very happy with the result.

    Is it possible to mount a picatinny rail to the underside of the gas block for a bi-pod?

    Is this barrel mil sped 5.56 or SAAMI spec .223?

    • This is chambered for 5.56 nato
