Sonicore Rekkr OB

The Sonicore Rekkr OB is a direct-thread overbarrel rifle suppressor designed for semi-automatic firearms and offered in 5.56mm and .30 caliber configurations. Its overbarrel layout reduces the amount of added length at the muzzle compared to traditional forward-mount suppressors, making it suitable for rifles where overall length is a consideration. The modular design allows users to configure the suppressor length to balance compactness and sound reduction.

The Rekkr OB is manufactured from 6026-T9 aluminum with 303 stainless steel components and finished with a black, non-glare Mil-Spec hard coat anodize. It incorporates aluminum baffle modules with stainless steel inserts forming a reinforced internal core, along with an integrated stainless steel muzzle brake that serves as a sacrificial baffle and helps maintain thread tension during firing. Thicker wall construction, external knurling, and a stepped rear profile support durability, heat management, and compatibility with common AR-15 handguards.
