Thompson/Center | G2 Contender Pistol Barrel | 223 Rem | Blue

Thompson/Center's G2 Contender barrels are fully interchangeable across the entire Contender lineage -⁠- barrels made for the original Contender fit the later G2, and G2 barrels fit original Contenders with serial numbers above 195000, genuine cross‑generation compatibility most manufacturers don't offer. Available in blue or stainless steel across an unusually wide range of lengths (6 to 24 inches) and calibers from .17 HMR up through .45 Colt/.410, letting one pistol frame cover everything from small‑game hunting to genuine handgun‑hunting calibers. The platform that arguably started the whole interchangeable‑barrel single‑shot category.
