I came up with the idea while repairing a cracked hand guard. After you put the epoxy in the crack, snap the coins in and the epoxy will mostly squeeze out. Wipe with vinegar and the crack will usually be as invisible as can be and, just as importantly, you will not be inducing new stresses caused by creating an epoxy wedge in the crack.

I just got a 98 Rifle with a crack in the hand guard behind the rear sight.  It does not run from the cutout for the sight to the rear of thehand guard, but it is there and it is noticeablele to the naked eye.  How do you manage to squeeze it open without causing additional damage?  I've repaired other hand guards, but none of them had the potential for additional damage like is possible with the Krag hand guard.  Primum non nocere (do no harm) is certainly involved here.

Thanks,
