Our 300BLK don't need to be regulated......SEE WHY!
Posted by Charles on 9/6/2022 to
Our 300 Blackout systems are non-adjustable. Why?
It was determined during our R&D process that by utilizing a piston of a particular size and proper positioning of the gas port location we could achieve outstanding reliability without adding the complexity of a regulated system. Although we are known for our regulated piston systems, and really believe in them because they offer significant benefits with typical rifle calibers especially with suppressed firearm due to suppressor backpressure that may increase bolt carrier velocity by as much as 30 percent.
Our regulators provide a means to mitigate over gas situations and compensates for underpowered ammunition which is common with standard rifle calibers; however, 300BLK self-mitigates these gassing issues to a significant degree by virtue of its design. For example, with subsonic ammunition you have a bullet that is typically twice the weight of a supersonic bullet, and it is moving at less than haft the velocity. This creates a situation where subsonic bullets are in the barrel about twice as long providing a longer gas impulse. Conversely supersonic bullets are moving about twice as fast and at much higher pressure. These characteristics enable us to utilize our piston system and gas port positioning to effectively balance between the longer dwell time of subs versus higher peek pressure of supersonic ammunition.
The key here is we balancing gas pressure and dwell time with piston size and gas port positioning to optimize reliability, thus eliminating the need to regulate our 300BLK Piston Uppers.

SMALL ARMS SOLUTIONS PISTON REVIEW

We would like to think Chris at Small Arms Solutions for doing a review. He contacted us a few months back regarding our bolt carrier groups and we sent him one and asked about reviewing an upper which he graciously said yes.
Why a Silencer Gas Setting?
Posted by Charles on 11/1/2018 to
The amount of gas in your face is directly related to how much back pressure the silencer creates. Secondarily gas in one’s face can increase or decrease depending on how fast the firearm’s bolt unlocks and extracts a fired cartridge. The velocity at which the bolt unlocks and extracts a fired cartridge increases on average 20 to 30% due to silencer back pressure. It should be noted that gas in the face is not a significant issue with bolt action firearms because the bolt stays lock until the silencer back pressure has dissipated.

Black Rifle Arms® .308 Piston Uppers vs .308 Piston Conversion
As of late, we have been getting a lot of inquiries if we have a .308 gas piston conversion, so we feel the need to address it.
