I have these two Shorty barrels that i got in a lot of stuff i bought. I'm not too familiar with shorty conversion stuff so please bear with me and ask any questions you may have. The 7.62 looks to have the end booster support piece welded in place. the 30/06 one does not look to have that piece added. they both measure 16 1/2 from end to end. Rifling looks good to me. Asking $100 for both of them they are still heavy so i would say $25 shipping should be enough i will cover the difference if it does not cover it. I will take postal Money order. First i will take it gets it.
