Broach Cut Rifling For Optimum Accuracy With All Bullet Types

Ready-to-install, match grade 416R stainless steel barrels with broach-cut rifling provide outstanding accuracy with both copper jacketed and lead bullets. CNC machined to precise tolerances, then hardened to Rc 40-42 for superior strength and durability. Chambered for maximum case support. Drop-in installation, may require minor modifications to fit certain models. Ported models are longer than factory barrel and have two ports on top, at the muzzle, to vent blast upward and counteract muzzle flip to help you get back on target faster. Threaded models are also longer than factory barrel and come pre-threaded to accept screw-on aftermarket compensators. Thread pitch is indicated in table; comes with a thread protector. .40 S&W-To-9mm Conversion barrel converts M&P Compact .40 S&W caliber pistols to shoot 9mm ammunition; 9mm extractor and ejector must be installed to ensure reliable shell ejection. .40 S&W-To-.357 SIG Conversion converts a full-size M&P .40 S&W pistol to shoot .357 SIG.
