Quote HistoryOriginally Posted By TinyCrumb:
- .070 is the Crane-spec gas port size for the 10.3" barrel to cycle reliably with M855 62gr mil-spec ammo both unsuppressed and suppressed with an H2 buffer. - .070 may not cycle reliably in a civilian gun unsupressed because we run lots of ammo that's significantly less pressure than mil-spec M855. The usual suspects are steel case (Wolf, Tula, etc…) and PMC 55gr. - .070 will most likely cycle reliably suppressed in any civilian gun because the added back pressure from the suppressor will help cycle the gun even with low pressure ammo. - ~10" barrels experience accelerated gas port erosion compared to longer barrels with longer dwell time. So as time goes on and after thousands of rounds, the port will open up slightly. If the gun does not cycle reliably at first with a certain type of ammo it might later. - Most people have have good luck with shooting all types of ammo with a .070 unsuppressed by swapping out for a lighter buffer. Using a standard Carbine buffer instead of an H2 will decrease the amount of pressure needed to cycle the action reliably. Thank you, sir! |

If you're not chopping a Colt barrel down, there is literally no other commercially sold barrel to that spec or more clone correct.

I have thought that myself, but its interesting, even on a moonless night with my sony, open for 8 seconds I start to get the motion of the earth rotating, the stars start to elongate. Im sure on a full moon with little to no ambient light... you could do a lot with those older camera bodies....
sorry...To much talking about cameras... Pic thread: pics of my home boy PewPewchris and his PR CQBR

What was/is the purpose of the CAS-V? The continuous top rail? In the pre-solicitation notice in March 2005, FISCSD required 104 extended length M4 carbine handguards as follows. The preferred design is a two piece chassis that mounts piggyback to flattop upper receivers and fits around fixed M4 front sight towers. The model must be tan in color. The handguards must accept detachable MIL-STD-1913 rails and to be equipped with two 4-inch rails, two 2-inch rails, and one 6-inch rail. Four months later, in July 2005, Abrams Airborne Manufacturing (Vltor) got the sole-source solicitation for 433 CASV-EL handguards, as well as 97 5-position RE-1 receiver extentions. Why the piggyback design was the preferred choice, I do not know. They seemed to be after modularity. |

I think it's more determined by the attempt to adhere to the spec sheets associated with the fielded weapons. The attempt to chase down rare parts and replicate those weapons. Even if it is to clone a specific rifle that might only have been seen once "in the wild" TNW has a great example of this with one of his cqbrs. The purpose isn't to shame those who are giving it an honest effort, but the problem lies when anyone just slaps an SBR upper together and labels in mk18 with no regard to the sopmod parts listing. ECs probably got the most room to scrutinize in here since he has an actual m16 lower followed closely by milspec since he is the resident clone nazi.

I usually run a black SOCOM-SB on it. I really like the config as does anybody that shoots it. I used a Colt 6921SP upper (factory 10") and the gas port is HUGE! I'm running an H3 buffer and a Springco Orange (308) spring. Even with that it'll cycle Wolf with no can and gas with the can is acceptable. |
