What does Suppressor Optimized & Suppressor Dedicated mean?
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 the need for additional adjustable gas system components.
The Suppressor Dedicated variant SOFR Uppers are designed more for traditional baffle stack suppressors, however most “reduced back-pressure” suppressors will still cycle reliable with these uppers too, as they still provide a moderate amount of back-pressure, but it varies by manufacturer. However, we don’t recommend the Suppressor Dedicated SOFR for a true flow-through suppressor.
The Suppressor Optimized variant will provide the end user with all the benefits of a properly sized gas port that is optimized for suppressed use, however it still maintains the ability to function without a suppressor. When shooting without a suppressor, you will need to run a standard 3oz carbine buffer and standard strength spring or an A5H0 for most applications.
Are Suppressor Dedicated Rifles reliable?
We test our barrels with a couple dozen suppressors with varying lengths and baffle designs. We found that with the variance in baffles designs and with the huge variance in ammunition pressure, that small of a port size can be problematic. We even found that it can create reliability issues in very cold temperatures. These variances lead us to develop our gas ports to allow enough gas to compensate for the pressure variances on the commercial market and allow the end user to slightly fine tune their buffer system to optimally for their specific configuration.
Our suppressor only barrels were designed with a requirement of an improved recoil and reduced gas to the end user’s face while still maintaining 100% reliability. Our suppressor only barrels will run with any ammunition and any baffle stack suppressor, whether it’s an extremely short K suppressor or a long L suppressor.
How accurate are the SOB Barrels?
We have personally and have had multiple customers report 1 MOA to sub-MOA results. For example, we’ve had our 13.9” 5.56 SOB out to 700y and achieved consistent results with 77gr IMI razor core. However, consistent precision is only achieved when the ammunition is equally consistent.
Accuracy & precision is impacted by so many variables. Ammunition plays a major role in precision, both in finding the proper load but also sourcing ammunition that is consistent. Consistency of the bullets, powder charge, brass, and primers all impact results. The individual shooter and specific rifle configuration also produce its own variation.
What buffer system should I use with my SOFR Upper?
We provide buffer recommendations checkout barrel specifications on the product page for SOFTR Upper & SOB Barrel on our website, we provide recommended buffer & spring configurations. Due to the variances in proprietary buffer systems, we only provide recommendations for Carbine and A5 Buffer systems, however proper configuration with proprietary systems is easily achievable in most cases.
Do you accept FFL Transfers for local customers?
No, we do not accept FFL transfers unless the transfer is associated with a pre-agreed upon project that we are building for you. Email Sales@OvertIndustries.com to discuss your project first.
