Description
When modularity, accuracy and quality are all important, CMMG's Mk4 Heavy Tactical Piston is the upper of choice. The Mk4 Heavy Tactical Piston upper sets itself apart with the new RKM9 KeyMod free floating hand guard, a lightweight low profile alternative to quad rails with even greater modularity.  The Mk4 HTP features a blackened salt bath nitrided 4140 chrome-moly steel barrel in a heavy taper profile and thread protector. The CMMG piston uppers run cooler, smoother, and more reliability, with less wear and easier maintenance.
