I bought several from e=gun parts pricey but dood condition, I picked some up in the french caliber, cut the mag clamp off and tacked them on some metric FAL mags and presto 20rnds only problem is they will not hold bolt open on last shot. Mine was a Century botch job I bought for 200, I replaced the recoil spring and firing pin (E=gun parts) polished the chamber and shoot Wolf 308 for practice and Hornady TAP for serious social encounters. The steel cases do not expand like brass thus eliminating extraction issues that plagued these otherwise excellent MBR's. They balance well, built like a tank, work , and beauty being in the eye of the beholder I think it is a perfect truck gun.
