Assembly Process

This Upper Receiver assembly was properly assembled using Aeroshell 64 on the barrel extension and barrel nut after the threads were properly seasoned. The barrel was also properly dimpled using a BRD Engineering Pro Jig and the gas block set screws were tightened using Rocksett for maximum reliability at high temperatures. The handguard was assembled using Loctite 242 on the rail mounting bolts.

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.

Gas Port Diameter = 0.073" 

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.  

1. Unparalleled Suppressor Compatibility: Our barrel is designed with suppressor use in mind, featuring a conservative gas port size that provides a soft, flat shooting recoil impulse and less gas to the end user's face with their suppressor. We recommend a Standard Carbine 17-7 Steel Spring or Sprinco Blue & H Weight (3.7oz) Buffer or a Standard A2 17-7 Steel Spring or Sprinco Green & A5H2 for most suppressor applications, however for newer reduced blowback suppressors, a Standard (3oz) or A5H1 buffer may be required. When shooting unsuppressed, performance can vary depending on the specific muzzle device and ammunition and you may experience cycling issues, or a failure of last round bolt hold open function - Keep in mind this barrel is intended for suppressor use but in most cases will still function unsuppressed. 
2. Premium Materials: Crafted from high-quality, precision-machined stainless steel, our barrel is built for hard use. It's corrosion-resistant, durable, and capable of withstanding the rigors of extended use. 
3. Precise Rifling: The barrel boasts precise 1:7 twist Button rifling, optimizing stability and accuracy with a wide range of bullet weights. Whether you're shooting lightweight varmint rounds or heavier match ammunition, expect exceptional accuracy downrange.
4. Versatile 5.56 NATO Chamber: Our barrel is chambered in 5.56 NATO, providing the versatility to shoot both 5.56 NATO and .223 Remington ammunition. Enjoy the convenience of switching between these popular calibers without compromising performance.
5. Overt Industries Reliability: Overt Industries is known for its commitment to quality and innovation. We 100% QC every SOB barrel and ensure that the gas port diameter is within 0.001" of our specification of 0.073". Our suppressor-optimized barrel is no exception, embodying our Hard Use - Zero Sacrifice Ethos. 

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.

Overt Industries AR-15 Hard-Line MLOK® Rail System 

The Hard-Line MLOK® Rail System was designed with an emphasis on Rigidity, Ruggedness, and Simplicity. 100% Made in the USA, the Hard-Line MLOK® Rail System utilizes a Three Point Mounting System to ensure that the handguard clamps securely to the barrel nut without the possibility of unwanted rotation.

Machined from American sourced 7075 T-6 extruded aluminum, the Hard-Line MLOK® Rail System offers increased strength, rigidity and reduces overall handguard flex by removing often unused MLOK® sections in order to enhance the structure of the rail system. The increase in handguard rigidity reduces handguard flex resulting in a stronger mounting structure for Laser Aiming Devices. We also integrated chamfered serrations to the exterior of the rail system in order to provide maximum grip friction to the end user. 

Features:

• Free float design
• Chamfered Serrations and Leading Edges 
• Ambidextrous Integrated QD Sockets 
• 7-Sided M-LOK®
• 2" M-LOK® Attachment
• American sourced 7075 T-6 extruded aluminum
• 4140 Steel Barrel Nut
• MIL-A-8625 Type III Class 2 Anodizing
