i just tried out my new cmmg upper. being this is NY state i went with a permanent muzzle brake instead of a trip to jail :rolleyes:
this thing is pretty loud. i’ve got a 5m2 phantom brake on it.
it’s tolerable, but i’m wondering how long i’m going to want to put up with it.
i’m wondering if i could widen the bullet exit holes to reduce the amount of gas that gets directed backward. obviously recoil will be increased, but i can deal with that.
i should be able to do the mod with a drill in a few minutes…
Not being familair with NYS law in regards to the wording on the requirement, I would say leave it be. By altering it’s design, which would be approved by the BATF, it may render it unapproved. Reason being is that it may reduce the muzzle flash by opening up the exit hole. Besides, imagine going to far and hitting the crown.
