View Full Version : M1 gas plug question

I'm considering a ported gas plug and was curious if a BM59 plug would accomplish the same physics as the commercially available plug i've seen on the available ?

Although the BM59 gas plug does have a semi-circular recess I am not sure it is large enough to have any real effect on pressure.

Its basically the same thing as Garand Gears. Personally I do not buy into the one size fits all gas screw. The adjustable is the one I recommend
