MAC isn't using a 3-lug, though. If it's possible but an ordeal to remove the suppressor while it's housed in the carbine handguard, I'll pass on getting the handguard.
A 3-lug adaptor should make it stick out a little further than MAC's, so I'd love to hear feedback. I'm sure there are people here who have the handguard AND the 3-lug with a similar length suppressor as MAC is using.
