T/C Contender G2 Locking Bolt Set - Tool Steel by EABCO- Precision machined tool steel barrel locking bolts for TC Contender and G2 Contender barrels. 2021 was a worrisome time when S&W announced they were quitting the Thompson Center brand. We could NOT get locking bolts to build our custom TC Contender barrels. We tooled up to machine these excellent locking bolts from tool steel (factory bolts are molded). We've been installing these in our EABCO Accuracy Barrels ever since.- These bolts are interchangeable with factory bolts and fit factory barrels as well as our EABCO Accuracy Barrels. Sold in matched pairs.
