Gas Piston Retainer Pin

[Antonrx]

Ok guys, so, I realized that no amount of tightening to the lock ring on my after-market gas piston is going to keep it in place. My bolt carrier has the retaining pin hole, so, I want to get a new piston that will accept a pin... What will fit my MAK 90 bolt carrier? Will the bulgarian ones they sell on KVAR do the trick?

Thanx..

Really the simple solution is to tighten the piston down and then back if off
about one full turn. Drill a hole thru the carrier pin holes and then pin it.
Use a 10 D finish nail for a pin. Mash the ends, file smooth. done.
