2018年10月21日 · I would put the Guard on par with the MP5 in regards to suppression. MP5 has a slight edge on smoothness over the Guard (but I'm still working on tuning the Guard some more) Since the Guard is basically an AR/M16, aftermarket support is the best as is tuneability.

2018年11月18日 · (note that I've also tested the 2.0 and 1.0 Guard weights but left that data out for brevity, pictured below is a standard Colt 3.5 Oz weight same as the heaviest one CMMG provides in their tuning kit.)

2019年6月14日 · You dont need to use CMMG's Glock mag lower, you will however need to remove the ejector from the lower (CMMG Guard bcg has ejector in bolt) and replace it with a magazine over insertion stop. Endo mags are nice because you can use an existing standard milspec lower and switch back and forth between 9mm and whatever other caliber you would like ...

2018年8月9日 · As far as 9mm uppers, from what I read initially, the CMMG Guard upper can use a regular buffer/spring due to their radial blowback design, so if a Guard upper would work with the EndoMag, it would be exactly what I was looking for - swap uppers, insert mag, and go (just like I currently do with my 5.56 and 300 Blackout uppers).

2019年3月17日 · I see that CMMG offers tuning weights that can be fitted into the rear of the Guard/MkGs/Banshee bolt for suppressed or +P loads. Any good reason that you couldn’t instead change the buffer? It seems to come with a standard carbine buffer, so swapping to an H or H2 buffer seems close to adding their 1oz or 2oz tuning weights, as far as weight ...

2018年8月21日 · CMMG states that their 9mm and .45 ACP Guard systems should be used in conjunction with their Guard upper receivers which have an enlarged ejection port for increased reliability. I have been running built PCC's for some time, two in 9mm, and two in .45 ACP with conventional mil-spec upper receivers with no issues.

2019年4月26日 · CMMG Guard/Banshee lowers do not have an ejector "hook" in the lower like many other dedicated 9mm AR lowers. - Endomags come in two versions. One that has a built in ejector (in the magazine) for straight blowback 9mm AR's and another version for the CMMG Guard/Banshee without ejector (in the magazine) since it is not needed in a CMMG Guard ...

2018年3月4日 · The setup is CMMG 9mm guard lower, CMMG 8 inch upper, standard carbine buffer and spring. But also had issues with A5 VLTOR system. Trigger group is Geissele SSF. I get the issue in both semi and full auto with my RDIAS

2018年11月17日 · However, I would still give the MP5 the edge over the Guard for items 1 and 2 as you state but I think one needs to consider the overshadowing availability of parts of the AR platform and familiarity of controls.

2013年10月19日 · To add, since its a two piece tube, being the tube itself, then an inner barrel nut that is first threaded onto the receiver before the tube section is threaded onto the barrel nut, before you go to remove the barrel tube, remove the front gas block and gas tube first.
