Looking past the outdated grip and buttstock, this is a very good rifle that deserved a much better trigger.

Smooth machining and sturdy construction made the CMMG handguard the favorite in our tests. With so much ventilation, it never seemed to heat up. The bottom and sides featured a Keymod pattern for near unlimited mounting options. The circular cut was for a quick detachable sling loop.
The seam line on the CMMG hammer indicates this is a cast part, which is not unusual. But most such components are polished and tumbled to refine its surface.
The CMMG Mk4T swung from target to target effortlessly, but we pulled one shot wide left. While handling was superior, the creep-ridden trigger was a detriment to accuracy under stress. Firing from the bench, patience was an option, but at speed, the poor trigger finally caught up to our shooter and foiled his aim. We saw this one selling for $885 at retail.
