With DoD interest in 300 PRC for use as a Precision fire cartridge, CMC Triggers wondered if it could be used in a gas operated rifle. So far, all of the weapons to fire this cartridge have been bolt guns.
This is a sneak peek of the proof of concept CMC put together. Based on an AR design, they wanted to see if it could be done and how it would impact the accessories they make, like triggers and bolt carrier groups. They have no plans to place this into production.
