I’m wanting to do a pin and weld 13.7-13.9 build and pin a keymo flash hider or the nox from SOLGW. I am having a hard time finding handguards that will fit tight, but still will let me attach my sandman s. Looking for pics/advice.
I know it's not relevant to the setup your after, but this should give you some frame of reference. 13.7" barrel, HG is 13.3" at the lingest point, 12.8" at the inside of the concave.
