The 7.62mm NATO Navy M1icon barrels still command an exceptional premium. I'd guess that unless you had put a few thousand round through it in match shooting the SA 7.62 Natos built in 65 and 66 will always command a pricetag in excess of $500. They are certainly far more rare than any VAR and most of them...especially those air gauged by Don McCoy at NWS Crane Indidana will out shoot any other military M1 barrel. Beach
