Why This Rifle Matters
The adjustable gas block is the standout feature here. Whether you're running subsonic ammunition through a suppressor or experimenting with different commercial loads, you can dial in the gas system for optimal performance. This level of adaptability is typically found on much more expensive platforms.
The side-charging handle and reversible controls make this rifle equally at home in the hands of left or right-handed shooters. The compact BR4 platform keeps overall dimensions manageable without sacrificing sight radius or handguard real estate.
This is a rifle built for shooters who understand that precision comes from attention to detail—and CMMG has attended to the details that matter.
