This is about a CMMG product and company statement. I am not seeking opinions on CMMG as a company.
I am seeking opinions on a particular SBR upper and their statements about an improvement for SBR reliability.
With that out of the way, here we go.....
CMMG M2SG 10.3 Upper
http://cmmginc.secure-mall.com/shop/images/731.JPG
New 10.3" M2SG MedCon upper. The M2SG 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.
Here are my question:
1) LMT has a very good rep all the way around, and their SBR uppers get great reviews...without the "enhancements" noted above.
Is CMMG on to something or is this a fix for a non-existant problem?
2) Is there merit to this CMMG upper design? If so, what? Would it actually improve reliability in your opinion?
