I agree with you that it looks bad with the 13.8” Handguard. Leaving that much barrel exposed also creates the potential for damaging it, as well as shifting POI from inadvertently resting the barrel on an object when shooting off barricades, rests, etc.
I’ve got an 11” converted to NR on the way, and I’m going to put the 15.8” Handguard on. It’s aesthetically the best looking configuration for the NR Bren 2s. I’ll just have to modify it a bit so I can access the gas regulator for adjustment. Seems like the best solution if running them NR.
That’s not going to fit my dude the 15” handguard is for the longer gas system on the 16” carbine not the 11”
