I have one M134 Heavy barrel set and support available. The barrels have the current issue USGI straight profile. They are FN barrels. They are chambered on 7.62x51 (.308). They go for 5k plus on most sites I’ve seen I’m asking for $$3000 I think that’s more than a fair price it does have scratches but nothing a cerakote can’t fix I am also open for trades
