I am planning on installing a Midwest Industries gen3 LWM M-Lok handguard on my Colt LE 6920 OEM2. Does anybody have experience with these? Do I need to remove the factory barrel nut ?
I'd check with Eric aka hdfireman. I beleive he uses them on some of his builds. I'd say you do need to change the barrel nut since this handguard comes with one meant for it.
