6315RF & 6310RF
RF SERIES MUZZLE DEVICES
REVIVAL DEFENSE X FORWARD CONTROLS DESIGN
Background
While the design philosophy may not matter to most, we felt as if we should explain it to help better understand why the RF series of muzzle devices was created. Revival Defense was established in July of 2021 when we were still in California, and if someone told us then that we would have a product of our own on the market just over a year later, we would have a fairly hard time believing them. While designing and creating products that have a practical purpose has always been a desire, it is not something that we thought would be a reality this early in our journey, especially in collaboration with a company like Forward Controls that is regarded for their for their focus on function driven, quality products. The products we sell and the customer service that we try to provide to our customers are a reflection of what matters to us most; quality and purpose. Function First is something that we often say to customers who asked why we created the 6315RF and 6310RF. When we had the idea for the RF series devices, we reached out to our friends at Forward Controls Design, who have created a vast amount of well thought out, function driven products for the firearms industry. Forward Controls saw the purpose behind the RF series devices, and we decided to create the muzzle devices as a collaboration product, using design ques from their 6315 line of muzzle devices. We are extremely grateful to have been able to collaborate with FCD on the RF line of devices.
Design
After spending plenty of time using various suppressor mounting systems, the Rearden ATLAS / Plan B mounting system quickly became our preference. The Rearden ATLAS system uses a short, lightweight threaded taper mount muzzle device, but none of the devices on the market seemed to check all of the boxes for the features we wanted on a muzzle device. What we wanted is; A closed tine, closed bottom flash hider, that was a durable and consistent suppressor mount without adding extra unnecessary weight to the front of the rifle, which is where you absolutely do not want to add extra weight. As we said in the background, there is a purpose behind everything we do, and the features on the RF Series Muzzle Devices are all for good reason:
Flash Hider: We tend to prefer flash hiders over muzzle brakes on most platforms, for many reasons, but mainly because the benefits of the flash hider outweigh the consequences of using a muzzle brake. Muzzle brakes provide recoil mitigation, however the byproduct is an excessive amount of concussion and flash, on a platform that doesn't generate much felt recoil in the first place. With a flash hider, we achieve significant signature reduction with a minimum amount of concussion. Being such a short device, folks always question how well it can mitigate flash, and in our observations, we saw similar flash mitigation to a standard A2 Birdcage, even with our device being shorter. This is primarily because we enlarged the top ports as much as we could to maximize the performance of such a short device.
Closed Tine: Closed tine devices reduce the likeliness of the device snagging on things like foliage, vines, etc. Closed Tine devices also tend to be stronger, as the device does not have any exposed prongs. Using a closed tine flash hider also allows us to have a completely closed bottom.
Closed Bottom: A closed bottom helps us achieve two things, dust signature mitigation and compensation. The primary reason why we wanted a closed bottom is dust mitigation. If you’ve ever shot an A1 style, open bottom muzzle device in a dusty area or an area with light debris, you know how obnoxious the concussion can be on debris and dust. While this is the primary reason we wanted a closed bottom, one of the byproducts is extra added compensation.
Although the video does not show it as drastically as it may be in practice, this short video shows the difference in concussion on loose debris with a 6310RF vs a standard A1, open bottom device

Suppressor Mount: If we weren’t planning to mount a suppressor on our rifle, 9 times out of 10, they end up with a simple A2 Birdcage flash hider. Why? Because it’s cost effective and mitigates flash extremely well. Now in our case, we wanted a device that didn’t sacrifice its performance as a bare device with no suppressor on it, but also was a durable and consistent suppressor mount that didn’t add a lot of weight or length to the front of the firearm. A taper mount was the answer. The taper provides a consistent seal for the carbon, making sure that there is no leakage out of the rear, while also keeping the can on tight under hard use preventing it from coming loose. By making our device Rearden ATLAS / Q Plan B Compatible, we also effectively made our device compatible with a virtually unlimited number of suppressors. We also were very careful in making sure the device maintained a short enough length, so the overrun in the ATLAS or Plan B adapter was not long enough that it would affect compatibility with certain suppressors that have limited space in the initial blast chamber such as the CGS Helios QD and others.
The RF Series muzzle devices also feature internal grooves that allow for more expansion of gasses to aid in additional flash mitigation. Another small, yet important feature on the RF Series of muzzle devices is the standardized wrench flats. One of the largest complaints that we had with most of the Plan B compatible muzzle devices on the market is the lack of proper wrench flats, either requiring a unique sized wrench, or a method of installation that doesn't allow the end user to properly install or remove their device. We implemented standardized 3/4" wrench flats that allow the end user to use common muzzle device wrenches, including our favorite, the FCD JMW. The 6315RF and 6310RF are precision machined out of 4140 steel and then heat treated and nitrided for a durable construction that can withstand extreme temperatures. As we said before, the design for the 6315RF and 6310RF was based around practicality and function, so the aesthetics were not our primary concern, but still something we did pay attention to. The RF Series devices follow the same form as Forward Controls 6315 line of muzzle devices paying homage to the Stoner 63 Light Machine Gun with the “63” in the name and the shape of the ports of the design heavily reflecting those on the flash suppressor found on the Stoner 63 Light Machine Gun. The RF in 6315RF and 6310RF stands for: 6315/6310 Revival Defense, Forward Controls, as the RF series devices are a collaboration product between both us and Forward Controls Design. 6315RF is threaded in 1/2x28 and 6310RF is threaded in 5/8x24.
The RF Series devices are available directly from Revival Defense, Forward Controls Designs, and various other dealers:
