As you’d expect, we accomplish this by utilizing tapers on both the Cherry Bomb and the Plan-B mount. This provides a better lock-up thanks to increased surface area, guarantees improved alignment of your silencer, and protects your threads from carbon exposure. No shims, washers, latches, springs, gimmicks, or timing of the muzzle device required! You’re welcome. COMPATIBILITY (I’m sure we missed some) Plan-B: OMEGA 9K: SilencerCo Omega 9K, Omega 45K, Octane 9, Octane 45, Obsidian 9, & Obsidian 45, Harvester 300 SPECS WEIGHT: OMEGA 9k 1.3 oz MATERIAL & COATING: Heat Treated 17-4 Stainless Steel MOUNT: Cherry Bomb Muzzle Brake REQUIRED TOOLS: Props to SilencerCo for having the forethought to include the tools needed to install replacement mounts. “Can I use the PLAN-B with Cherry Bomb on my 90° shouldered barrel?” Yes. Here’s what we recommend for a minimum shoulder for our Cherry Bomb muzzle brakes. DOWNLOAD INSTALLATION INSTRUCTIONS Please refer to your firearms safety manual before performing any maintenance on your own. Seek help from a qualified gunsmith if you don’t know what the fuck you’re doing. Cherry Bomb to Barrel Remove muzzle device from your barrel. Clean and degrease muzzle threads. Do not use steel tools for cleaning. We recommend using a piece of solvent-moistened Scotch-Brite™, or a brass or nylon brush. Using a 1/2 inch socket and a torque wrench, tighten Cherry Bomb clockwise to 20-30 ft-lbs. The use of Rocksett won’t hurt either. Plan-B Mount to Silencer Refer to your silencers manual to remove their mount. Hand thread the Plan-B mount into the silencer. Take care not to cross thread it. Torque Plan-B mount into silencer to approx 35 ft-lbs (refer to your silencer’s manual) using the tools provided with your silencer.
