A while back I read of some rifles that where used at one point that where BAR sporters in 300win mag with 20rd detachable mags. They also had 1 piece stocks(mcm maybe?) and heavy barrels. Anyone know of someone who is building clones? Or anyone have any info at all about them? Guy on another site has a pic of a BAR in a 1 piece stock with a heavy barrel but it has the factory bottom metal. Seems like the company that made the originals was called ?-tech. Ring any bells?
