Black hole weaponry barrel Carbine gas port 1 in 11 twist. Twist on this is wrong for subsonics, initially BHW said that their type of rifling would stabalize with a 1 in 11, but now all their barrels are faster twist. Gas port on this being carbine position pretty much rules out subsonics cycling anyways, personally I think the gas port will need to be drilled out to function but I'm not gonna fuck with that since I have a second barrel that is pistol length gas that I'm keeping. Has 2 marks from set screws on gas block, unfired however. $200 or sexy trade? Barrel on the left.    Last edited by Kolat; 05-10-2011 at 12:59 PM. |
