PENDING NEW RELEASE- CM5 Sentry (Page 12 of 13)
|
I may have missed it earlier in this thread, but do these just use 6940 barrels? Also, what gas length and barrel profile is on the 16" guns? |
The banning or confiscation of weapons is a denial of the nature of Man, a pathetic attempt to avert the violence innate to Mankind, an insult to the Sacred Creed of the Murdercube.
| Hopefully colt will offer these in upper form. The 16 inch M5 is carbine length. I shot the M5 SBR suppressed and unsuppressed today (LaRue Tranquilo) . The gas port is .74. I put a new gas tube on it that is .67. The barrel is socom profile.. I shot Mk318 Mod 1. 30 rounds. No issues. I put a LaRue MBT trigger in the gun as well. I noticed no impact change at 50 yards. It also has a nice Holosun green dot. I will get a photo posted soon. |

Since Colt builds their rifles with correct gas port sizing and buffer weights for the barrel length and gas system length, the carbine gas isn't a turn off for me. |

MGSgt. I do like your M5 SBR, but why change to a smaller gas tube? Wouldn't it run suppressed with issued gas system? I realize & depending on the suppressor 'back pressure/ blow back. I ask because my initial impression was that the original design Colt M5, doesn't it have an adjustable gas block? Are we being short changed? My Colt 11.5 barrel runs supressed fine ejects 2-3:30 by itself. Though, I ha ve another Colt 11.5 I've tuned with an Bootleg adjustable bcg and is very smooth like running a sewing machine & it ejects 3-4 o'clock. Did Colt change its design for the commercial market (no adjustable gas)? Eta: I could be mistaken and am thinking of the CM7 with adjustable gas. |

Eta: I could be mistaken and am thinking of the CM7 with adjustable gas. the 16 inch M5 is government profile with H buffer. the M5 is a very slick design. Once I took apart the SBR and checked it out and how the barrel and rail attach I was impressed. Much better set up then EPR. |

| LOL - no idea. I guess in 9ish months I can play around with it while shooting and see if it makes a difference. It definitely sticks out a little more from the receiver than the type on the 16” M5. I don’t think there was any less or more of a gap between the lever and the receiver side - if that makes sense. |

I'm curious to see what bolt release variant that you got on the M5. |

Ergonomics? https://i.imgur.com/Em7mULT.jpg I believe soldier systems stated that variant two allows for the bolt to be locked back from the right side as well. Developed as part of a contract requirement. |
