- The Rekkr OB is a direct thread overbarrel sup- pressor, meant for higher volume shooting, with a lightweight and modular design machined from 6026-T9 Aluminum and 303 Stainless Steel, and finished with black, non-glare, Mil Spec Hard Coat Anodize. The modular design allows the user to shorten the can when compactness ranks higher than suppression. The walls of the Rekkr are thick- er than the Paradox to allow for maximum dura- bility under enhanced fire schedules. The Rekkr is kept lightweight through using aluminum baffle modules in combination with 303 stainless steel baffle inserts to create a steel “core.” An integrated stainless steel muzzle brake spins gas in a way to continuously tighten the suppressor onto your muz- zle. The Rekkr is perfect for those looking to add a value suppressor to their semi-automatic rifle. CALIBER COMPATIBILITY :30 : Up to .308 and equivalent,
