Tandemkross Shock Block Bolt Buffer

Every time a 10/22 bolt cycles, it slams against a small steel cross pin in the receiver. Over a high round count this beats a wear pattern into the alloy receiver and adds a sharp metallic clack to every shot. The Tandemkross Shock Block Bolt Buffer replaces that steel pin with an oil- and solvent-resistant polymer pin that absorbs the impact instead of transferring it. Shooters running suppressors notice the action gets meaningfully quieter, and the receiver wear pattern stops accumulating. Drop-in install (push the factory pin out, push the polymer Shock Block in), no tools required, $5, lifetime warranty. Cheapest insurance you can buy on a 10/22 you intend to put rounds through.
