I am building a 14.5" upper with a mid length gas system. from online stores they say that you need to use the triangle end cap with the specs I have vs. the round end cap.
Whats the differences with the caps? seems like a simple piece of metal I know they have different diameters and need the right diameter.
I am going to run a magpul moe mid length handguard, was not sure how that would match up with the triangle end cap.
anyone have some insight on this?
Thanks.
