If your front ferule is repro, sometimes the legs have to be squeezed tight onto the ferrule wood. The repro stuff is fatter here than a real ferrule. It should not touch, but the clearance needed is small. LOTS of GI rifles do touch here, it's an accuracy mod to achieve clearance.
Front ferrule pictured is not a repro. However the rear front handguard ferrule that pins into the barrel is a repro.
Front handguard is tight in both ferrules (it doesn't move)
I kind of prefer a ''tight'' front handguard, I don't want it to rattle. I'll bevel 30deg the gas cylinder and mod the tenon a bit tonight.
First test fire should be next week hopefully.
