- Great barrelI used this in a MK12 Mod1 clone build. I use Blackhills 77gr ammo that was designed for this barrel. I will say that using the clone correct flashsuppresor and suppressor collar fits perfectly. The barrel is solid and perfectly machined. I am still in the process or zeroing my rifle but I am certain that it will shoot sub MOA. I wish DD made this exact barrel profile for every length rifle. Especially 10.5 and 11.5. Buy this and build with confidence. Its an amazing barrel.
