Archived [ARCHIVED THREAD] - Any experience with CMMG SBR uppers & cans?
Posted: 8/25/2006 10:29:08 PM EDT
I'm interested in their dual gas port set-up on the 10.3" upper, but I'd like to know if someone here has any experience / opinions on it.  Here's a photo:



It's their CMMG M2SG 10.3" upper, and here's what little information they have on it:


New 10.3" M2SG MedCon upper. The M2 SG upper features a unique secondary micro gas block that diverts gas early into a standard gas tube with a second hole. Gas diverted forward enters an expansion chamber, created by forward portion of the gas tube, making initial unlock “softer”. This saves wear and tear on the weapon. Since the gas port is further from the muzzle there is greater residual pressure to ensure increased reliability with ammo ranging from 45 to 77 gr. This upper is built around the M2 multi-role barrel and comes with M4 handguards and is complete with bolt, carrier and charging handle. CMMG semi auto bolt carriers have the shrouded firing pin to protect against hammer wear. Upper receivers are "T" marked and include extended feed ramp cuts. Features include medium contour barrel, 11 degree recessed target crown, chrome-lined 5.56mm chamber and bore, 1/7 twist, parkerizing under “F” marked forged front sight base and magnetic particle testing on every barrel. When ordering with optional gas block, barrels will not be drilled for taper pins. Barrel is marked CMMG MPC 5.56 NATO 1/7.


Thanks in advance,


Saleen
