Our suppressor-optimized barrel is no exception, embodying our Hard Use - Zero Sacrifice Ethos. 

Barrel Specifications

Shooting a suppressed rifle offers many advantages to the end user, such as enhanced signature management, improved recoil impulse, and decibel reduction. However, suppressing a gas impingement AR15 does create some disadvantages due to the increased gas blowback that most suppressors create. The Overt Industries SOB Barrel line solves these issues and offers a reduced barrel gas port diameter that is optimized for the increase in gas blow back. This results in less gas in the face of the end user and improving felt recoil and eliminates the need for additional adjustable gas system components.

Suppressor Optimized Gas Port Diameter = 0.073" (Suppressed & Unsuppressed Capable)

Unlike other companies, we publicly disclose our gas port diameter so you, the end user knows exactly what they are purchasing. As shooters, we were frustrated when companies refused to disclose their gas port diameters and we were left to purchase barrels hoping for a desired result.

Buffer Recommendations (Please Read):

Suppressor Optimized: For Unsuppressed use a Standard Strength Carbine Buffer Spring and Carbine 3oz Buffer. For Suppressed use a Sprinco Blue & H/H2 Buffer is recommended - Keep in mind that every suppressor has varying back-pressure and buffer system configuration may need to be slightly adjusted for your specific application. 

Barrel Specifications

Our barrels include one gas block set screw dimple located directly under the gas port for enhanced durability and compatibility with industry standard gas blocks. 

Note this barrel is optimized for suppressor use with M193, M855, & MK262 ammunition, shooting without a suppressor or with lower pressure ammunition may result in varying performance.
