A NOTE FROM THE TEAM

[ JUNE 2024 ]
WE’RE BRINGING THE HIGH DESERT TO YOU.

It’s been an exciting spring here at OA Defense and we’re proud to usher in summer with the release of our new High Desert Finish for the OA 2311! As a Nevada-based firearms manufacturing company, the “battle born” mentality runs in our veins. Our new High Desert Finish pulls its color palette from the arid deserts and sage-covered mountains that surround our headquarters here in Dayton. This harsh and unforgiving landscape was the birthplace of the OA 2311 and it helped forge the robust design features of the platform.

We’re excited to share this piece of our local heritage with you and we hope you enjoy it as much as we do.
