A: Joseph - There are lo profile gas blocks available to fit virtually any AR-15 barrel in commercial production. The most common diameter gas block is .750" (Inside diameter) and the most common AR-15 barrel uses a .750" size gas block. There are other sized barrels (.875", for example) and they take a .875" gas block. Low Profile only refers to the outside diameter/height of the gas block, and literally means nothing at all about what barrel it will fit. Lo-Profile gas blocks come in various sizes, to fit the variously sized commercially available barrels. Just remember gas block 'size' is the inside diameter - gas block 'profile' deals with the outside measurements. I'm confident Troy makes a lo-pro gas block to fit this barrel.

A: Richard we already answered this. You're just stating the same thing we said. Be original.......Omg James, Don't you just hate how he obviously has no integrity .. and apparently no pride whatsoever. It's like he is an internet leach popping in an hour after we answer every question to get his 1 point. hahaha

A: I suspect that there is not a barrel nut included as it is nit mentioned in any of the specs at other online sellers or on the CMMG site Link https://www.cmmginc.com/product/barrel-sub-assm-16-1-mt-4140cm-sbn-5-56mm/ I would call CMMG to verify PHONE 660-248-2293 web contact link https://www.cmmginc.com/contact/

A: The barrel nut comes with the hand guard and is specific to the type and/or brand of the hand guard.
