Look for a Krink-style muzzle device on CMMG’s latest Mk47s, which acts as a booster, flash suppressor, blast reducer, and also slightly reduces recoil. "Our Krink-style muzzle-brake design was derived from an AK, which we modified to thread on standard AR threads,” said CMMG Engineering Manager Tyson Bradshaw. 
Similar to the original Mk47 Mutant design, the new rifles are built around the 7.62x39 mm caliber and feature a shortened AR-10 sized bolt-carrier group that is paired with a unique upper and lower receiver to minimize weight and increase ergonomics. One of the primary benefits of the Mk47 design is its ability to accept existing AK magazines and drums.
The new Krink models include the Mk47 AKS8 AR Pistol, Mk47 AKS8 SBR (short-barreled rifle) and Mk47 AKS13 rifle. The Mk47 AKS8 SBR (all NFA rules apply) has an 8’ barrel with a 9” RKM KeyMod Handguard, a Magpul CTR Buttstock and Magpul MOE Pistol Grip. It comes with a CMMG single-stage trigger and one Magpul AK PMAG.
The full-sized Mk47 AKS13 has a 13” barrel with the Krink muzzle device pinned and welded permanently to the end of the barrel to meet the 16" requirement for Title 1 Firearms. It features a 15-inch RKM KeyMod handguard, a Magpul CTR Buttstock and MOE Pistol Grip. It comes with a CMMG single-stage trigger pre-installed and one Magpul AK PMAG.
