i cannot confirm it as i have not seen one of these rifles in person to test with. your receiver threads need to be 1-1/4"-18 pitch and the area right under the picatinny rail above the barrel must be less than .650" and at least .5" tall from the bottom of the pic rail

Q
mikeymike, member, from WI, United States, asked on December 20, 2021

Does this go over a rifle length low profile gas block? Or do I need to go longer?

Manufacturer Answer
A
Answered by Midwest Industries, Manufacturer from WI, United States, on December 30, 2021

you will need to go longer. 12.625 will end at the start of the gas block leaving the gas block exposed. if your gas block is pinned this is not an issue if it is set screwed, regardless of dimpling, i would recommend a longer rail.
