Is the gas block pinned or set with set screws? Thanks in advance.

Answered by Hunter, Gear Expert, from OH, United States, on April 29, 2022

The manufacturer doesn't state if the CMMG, Inc RESOLUTE 300 Series Upper Receiver Group gas block is pinned or uses set screws. I recommend contacting CMMG in regards to that information.

JPR2, guest, from NY, United States, asked on January 22, 2021

Besides the price what is the difference between the resolute 100, 200 and 300 models

Expert Answer
A
Answered by Kurt Colbourne, Gear Expert, from IL, United States, on October 07, 2021

The main difference is in the kits. These are just the upper receivers so there's less of a difference. The Resolute 100 would differ the most as it would have an A2 style flash hider instead of a muzzle brake.

Does this fit on a mil spec AR lower? What kind of magazines does this take?

Expert Answer

The only upper that is magazine specific are the 22LR uppers. They will take the CMMG 22LR or similar pattern magazines.
