Bellm custom made from 1018 tool steel, our locking bolt roller will not bend or break.
Contender Locking Bolt Roller for two piece locking bolts only, will not be exact fit for the earliest 1 piece locking bolt.
These are a direct replacement for Contender barrels that came with the two piece locking bolts. The stock rollers are prone to shearing in the middle. I've seen it a thousand times they always break at the split. Will not fit the 1 piece locking bolts as a little too large in diameter. Part number #36 on Contender schematics, #27 on Contender Carbine schematics. MADE IN USA!
