Product Overview

*****This upper has been accuracy tested and the verification group is in the photos above for reference**** 

Our uppers are built using caliber-specific, precision-engineered reamers developed to maximize accuracy with today’s sub sonic high-BC projectiles. These chambers are proven to maintain consistent performance without degrading accuracy from fouling during extended round counts between cleanings up to 300 rounds. 

Each upper is paired with the longest functional gas system available for its barrel length and caliber, ensuring dependable operation with factory ammunition while minimizing recoil impulse and duration. The result is exceptional control, improved target tracking, and faster follow-up shots.

 

Designed to excel with both factory loads and handloads, these uppers also perform impressively with Sub Sonic 307 Sub-X and Hornady Factory ammunition. If you need a versatile setup, these chambers handle dual-purpose roles with ease—160 Grain TTSX have shown to be naturally forgiving, and our reamer is designed to make the most of the Factory Offerings. We have seen multiple 5 shot groups under .6 MOA from a few loadings.
