SilencerCo AC2627 ASR Muzzle Brake - Black Steel, 5/8"-24 TPI Threads, Single Port for .30 Caliber$79.90
Availability: In Stock
The SilencerCo AC1557 ASR muzzle brake is a .458-caliber brake built for shooters who want fast suppressor changes without fumbling. Built on SilencerCo's Active Spring Retention (ASR) mounting system, this brake pairs with a growing ecosystem of SilencerCo cans—Specwar, Saker, Omega, Hybrid, and Harvester Big Bore ASR models—for one-handed attach-and-detach convenience. The 5/8"-32 TPI threads fit most .458 rifles and magnum builds, while the three-port design tackles recoil and muzzle climb whether you're running suppressed or going loud.
Even without a silencer mounted, this brake delivers meaningful recoil reduction and helps you track your shots downrange. The black nitride finish on steel stands up to the punishment of magnum rifle use and brake fouling, resisting the blast erosion that eats through softer finishes over time. Installation is straightforward—shims are included to dial in the brake's timing and run-out.
If you're building or upgrading a big-bore rifle and already own or plan to own SilencerCo ASR silencers, the AC1557 eliminates the need for different brake patterns on different rifles. One brake, multiple cans, no tools required. That's practical suppressor-host versatility.
