11.5" 5.56 SOB - AR15 Suppressor *Dedicated* Barrel

Introducing the Overt Industries 11.5" 5.56 NATO AR-15 Suppressor Dedicated Barrel (SOB)

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 Dedicated Gas Port Diameter = 0.0595" (For Dedicated Suppressor Use ONLY) 

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 Dedicated: This barrel is designed for Suppressed use ONLY – We recommend a Sprinco Blue & H Buffer or A5H2/A5H3 - 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. NFA Rules Apply.
