Save some length while suppressing your .45 cal, or smaller, centerfire firearms with the ZEROED 46K. Built to the same exacting standards of durability as the standard length 46, the 46K still provides great noise reduction with a little less weight and overall length to boot. It's full auto-rated and perfectly at home on your centerfire rifle/pistol caliber rifle or PDW of choice. For durability without additional cost, the 46K is machined from 17-4 stainless steel and given a surface hardening nitride finish.
