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.
Is the SOFR-15 tuned for a specific Suppressor?
Simple Answer = No
When we developed our Gas Ports and overall Rifle System, we designed it to accommodate a wide range of suppressors and varying suppressor back-pressure. The suppressor dedicated series is compatible with all traditional baffle stack suppressors, we only do not recommend true flow-through suppressor designs, like the HUXWRX Flow. We recommend our Suppressor Optimized series for true flow-through suppressors.
While we do offer our own Hardline Suppressor series, our Rifles are not tuned exclusively for our own suppressors. We have not found a single suppressor that is not compatible with one of our rifle variants.
Is the SOFR-15 compatible with FRT’s?
Yes - Our lowers have an M16 cut trigger pocket and our bolt carrier groups have a full-auto profile. Therefore, both gas system function and our components will have no issues when paired with an FRT. We have also had multiple customers use FRTs in both our 5.56 & 300BO rifles. Our rifles will actually function better due to the tuned gas system, as many rifles will require excessive buffer weight with an FRT due to the drastic increase in bolt carrier speed due to being over-gassed. While you may still need to add buffer weight depending on your specific suppressor configuration, the required tuning will not be as drastic and will also help prevent premature component wear.
With any FRT, properly testing the rifle with the FRT is always important. Ammunition, the specific suppressor and its relative back-pressure, the buffer system, and even magazines are all part of the equation to ensure your FRT runs reliably. Most FRT companies provide recommendations on how to test their FRT.
What is the difference between the SOFR-15 Alpha & Bravo Series?
The Alpha Series is built on our V2 Forged Receivers.
The Bravo Series is built on our Billet Receivers which have more dynamic machining and feature an ambidextrous bolt catch/release, integral trigger guard, and flared Magwell.
Aside from the Receivers, all of the other components in both the Alpha and Bravo are the same high quality components.
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 14.5” 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.
I want zero gas to be expelled from the rifle, what barrel should I buy?
With both our Suppressor Optimized and Suppressor Dedicated Barrels expelled gas will be reduced, but you must keep in mind that any gas impingement system that vents from the ejection port will always produce "some" gas, as it simply wouldn't cycle without it. The Suppressor Optimized series is still a huge improvement over the vast majority of barrels on the market.
If you want to even further reduce your rifle’s expelled gas, a Suppressor Dedicated barrel is likely the best option.
What is the perfect brass ejection pattern?
This is a commonly misunderstood topic with the AR-15 Platform. While it can be a general indicator if a rifle is properly gassed, there are other factors that can change the ejection pattern aside from gas pressure.
An AR-15 ejection pattern doesn't always reflect its gas levels because ejection is actually driven by bolt carrier speed and casing timing. While gas pressure dictates this speed, many other mechanical variables, such as spring tension, extractor health, and ammunition, can significantly alter the angle at which the brass is thrown.
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.
I have a Huxwrx or similar Flow Through Design Suppressor, will it run with your Barrels & Uppers?
Yes. We always recommend our Suppressor Optimized Barrels and Rifles when paired with a Flow Through Baffle Design Suppressor. We also recommend that you initially run the rifle with a standard 3oz Carbine Buffer or A5H0 Buffer and Standard Strength Buffer Spring, then add weight or spring tension as desired to further tune the system for your specific application.
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.
