Cabela's had (maybe still has) 7.62 x 39 Red Army Standard for $4.59/box, or cheaper than 'Cheaper Than Dirt'.
So I picked up 50 boxes to feed this ↓↓↓ (not a stamped steel receiver, NJ-compliant as is the 15 round magazine shown).
Light trigger with a bit of take-up, seems to be shooting high even though it is claimed to have been bore-sighted at the factory. But having only put 90 rounds through it at this point I'm not going to go all crazy with front sight adjustments just yet, some of it is probably me.
