I have a pair of M16 BCG/CH packages available right now. The price is $180 each for (the pair of) BCG and CH, delivered. Paypal preferred, checks and money orders accepted. They're from Palmetto State Armory and are brand new. The BCG is an MPI tested 8620 steel M16 auto carrier/bolt . Again, brand new. The $180 price is all inclusive. That gets both shipped to your door in short order. I'd imagine these go fast. First PM/pay gets 'em. Check my feedback. I ship fast!
