Any chance we can get the official current production gas port sizing for the DD barrels from the company rep? I am specifically interested in the 11.5" and 10.3" stripped barrels but the sizes for the 14.5" and 16" mid gas would be great too. Please and thank you! @Marler5811 |

@SemperGumbi I started a thread about GP sizes awhile back, but somehow I unsubscribed from it and it got archived. It has the info you need. Gas port sizes. Colt's gas port sizes are: 10.3" - .070" (The NSW Crane spec for the 10.3" Mk18 barrels is 0.070") 11.5" - .070" FBI/HRT SOCOM 11.5" - .074" Colt 6933/Commando 14.5" - .062" (carbine gas) 16" - .062" (carbine gas) 16" - 0.071 (6960 mid-length) DD GP sizes: 10.3” - .070" 11.5” - .069" 14.5 - .076" (mid-length) 16” - .073 (mid-length) |
