Designed specifically for the red-hot, flat-shooting 17 Win. Super Magnum cartridge, the B.MAG Stainless Heavy Barrel represents a whole new class of rimfire rifle. Thread-in barrel headspacing, rear-locking lugs and a cock-on-close bolt maximize accuracy at long ranges, while user-adjustable AccuTrigger? technology allows crisp, customized trigger pulls. Added features include a stainless steel heavy barrel, rugged synthetic stock, compact action, center-feed rotary magazine, matte blued barrel and soft rubber butt pad.
