The Primary Weapons Systems MOD 2 FSC30 .308 muzzle brake delivers serious recoil management and flash control for .308 Winchester and other rifle platforms. Built on PWS's proven FSC (Flash Suppression Compensator) design, this 5/8x24 threaded brake reduces felt recoil while keeping muzzle flash out of your optics and sight picture—a dual benefit that matters whether you're hunting in low light, running a scoped rifle at distance, or shooting from a benched position where shooter comfort counts. The MOD 2 FSC30 is engineered for shooters who want a compensator that works across multiple calibers and doesn't sacrifice on-target performance for flash reduction.
Machined from 4140 steel and finished with PWS's durable FNC LIFE HD treatment, this brake handles the abuse of serious shooting. At 2.8 inches long and just 3.1 ounces, it's a compact addition to your barrel—light enough that it won't throw off your rifle's balance or add unnecessary weight to a lightweight hunting setup. The unique port geometry is the real story: it's engineered to suppress the concussive overpressure many shooters find fatiguing on the range, while the directional porting keeps flash signature minimal when you need it most.
The FSC30 is chambered for .308 Winchester, 6.5 Creedmoor, .300 Blackout, and 7.62x39, so if you're considering this brake for a specific rifle, verify that your barrel matches the .308 designation and threads. Right-hand threading (5/8x24) is standard for most .308 bolt guns and ARs chambered in these rounds. Installation is straightforward—this is a direct-thread muzzle device with no baffle system to clean or maintain, just solid steel and proven recoil-taming geometry.

Yes, if your barrel is chambered in .308 Winchester and threads 5/8x24 right-hand. This is the standard thread pitch for most .308 bolt guns and AR-308 platforms. If you're unsure about your barrel's thread specification, measure or consult your rifle's documentation before ordering.
The FSC30 is rated for .308 Winchester, 6.5 Creedmoor, .300 Blackout, and 7.62x39. If your rifle is chambered in one of these rounds and has a 5/8x24 threaded barrel, the brake will function across all of them with the same recoil and flash suppression benefits.
Yes. Flash suppression is a primary function of the FSC design. The directional port geometry keeps flash signature minimal, which helps preserve your night vision and keeps the muzzle flash out of your scope picture—useful for hunting at dawn or dusk when game is most active.
The brake measures 2.8 inches long, so your overall muzzle length will increase by roughly that amount. For most hunting rifles and tactical setups, this is a manageable trade-off for the recoil and flash benefits.
