Q

Biker Bob, member, from NE, United States, asked on January 24, 2023

is the gas block "clamp on" or "set screw"?

Expert Answer

A

Answered by Ethan, Gear Expert, from IL, United States, on August 28, 2023

Rock River Arms does not specify if their Coyote Carbine .300 AAC Blackout Completed Upper uses a pinned or clamp on low profile gas block. I would recommend contacting them directly for more information.
