Formerly the MK18 / CQBR / L119 / Variants Thread Part 2
Part 2 to this thread: http://www.ar15.com/forums/topic.html?b=3&f=118&t=271832&page=1 The CQB-R is a short barrel upper for the M4 weapon system. Later the Upper on an M4A1 or rebuilt M16 lower is designated by the US Navy at the MK18Mod0 The CQB-R / MK18 Mod O is generally(but not always) 10/10.3/10.5 inch barrel KAC RIS or RAS KAC NT4 Suppressor Mount LMT Rear Sight or KAC 300m Flip Up Rear Sight LMT Sopmod stock CQD Rear sling mount CQD forward sling mount Optics are often an Aimpoint M2 or ACOG. The Block II CQBR replaces the Knights rail and the fixed front sight base with a Daniel Defense MK18RISII rail. Knights flip up front sight is often used. When rear sights are seen they are often either KAC or Matech. Our British friends have the L119 carbine. The L119 is similar to a MK18MOD0. The rifle is made in Canada, with a 10 inch barrel. Every pictures I have seen the the L119 has a Trijicon TA31 or a TA01NSN ACOG that has a piggyback Trijicon MRD. Note: There is the L119, and the L119A1. I have seen both used to refer to the carbine, and I am not sure which is the proper nomenclature. Yada yada yada, will edit inore info later. Including some of the LMT 10.5 vs Colt 10.3 argument. |

I've noticed very little is written about barrel twist, granted the early barrels that were cut down M4's were 1-7 twist, is the 1-7 considered the norm in the MK18 or is 1-9 used also ?

He was the first to suggest the bathtub but he did suggest to crank up the white balance so that any details in the surface of the tub will wash out. Nice rifle.
