XCR-M brake - Pinned or not?

[Jonesyatpl]

Hey there,

Came into an old school XCR-M, the non-keymod version. I want to change the brake out from the AK looking version to an ATRS brake. I notice it has a hole on the top of the brake, and a corresponding hole on the bottom filled in. I am not sure if the bottom hole is just filled in to keep the muzzle rise down, or if it's a pin into the threads. I have heard some of the earlier ones came to Canada with the pinned brake.

I don't care if I destroy the old one, but before I go wrenching on the barrel and cause marring or damage, has anyone else tried removing these? I tried asking the (site sponsor) importer, and they couldn't give me an answer.

Thanks,

Jonesy

Depends on how "old school."

My XCR-L was the release just prior to keymod and it is not staked.

I think mine is version 1.0, if the serial is any indication. A lot of zeroes in it

Thought so. I might just send it to the experts at ATRS. I can imagine they install what they sell.
