Kilryth 0 Posted June 24, 2010 Report Share Posted June 24, 2010 Is the Bulgarian -74 gas block supposed to line up perfectly, or can it sometimes be off a little bit? i.e. does the rear pin hole always match up perfectly with the barrel's drilled hole? or does it usually require slight drilling to match them up? The block appears to be lined up straight, and I don't want to overturn it too much the wrong direction just to see if I can line it up another thousandth of an inch. It seems to be well positioned, since cleaning fluid and wire run down the gas block into the barrel smoothly, and the lug lines up straight with the handguard retainer.
