The AnechoX 223 OWNS AR-15 sound, recoil, backpressure, and muzzle flash! This ultimate compact titanium suppressor delivers ALIEN TECHNOLOGY level performance on your 22-550 or 5.56. The AnechoX 223 is the most accurate, lightest, quietest, lowest recoil, user-serviceable, Titanium suppressor ever made. It is the absolute state of the art and the pinnacle of performance on your 5.56mm/223 caliber bolt action or semi-auto rifle. A tiny 8.3 ounce, 6.6 X 1.6 gun muffler. All AnechoX centerfire suppressors are made of Grade 5 Titanium, with 17-4 Stainless blast chambers and blast baffles to handle extreme erosion, uncorking pressure, and temperature right at your firearm's muzzle. All use the unique X-Baffle Anechoic(TM) Chamber System with an interrupted central tube, and are finished with Cerakote C Series high-temperature thin film ceramic. The AnechoX 223 comes with a 0.8-ounce titanium 1/2X28 Direct Thread Adapter installed. It also accepts any AnechoX Direct Thread Adapters or any industry-standard 1-3/8-24 mount, including Bravo, Hub, Pistons, Boosters, Nielsen Devices, QDs, Tri-lugs, and more. To maximize sound performance and tailor your suppressor to your firearm, Caliber Specific Front Caps (purchased separately) are a great option. Available in six sizes and four colors, including 223 caliber. Especially if you are shooting powerful bolt action rifles, or slow firing your AR-15, you're gunna' love these caps! Attention: Maximum bullet diameter for the AnechoX 223 is .224. The AnechoX 223 is full-auto-rated to 50 rounds 5.56/.223. Rapid-fire rated to 15 rounds 22-25 or 220 Swift. Do not exceed 800deg F. *Rifles are rated with standard rifle barrel lengths. Round count must be reduced for shorter barrels or more powerful cartridges. Break In Period: All titanium suppressors shoot sparks downrange for the first 100 rounds or so, as microscopic bits of titanium raised during manufacturing are burned out. Cerakoted and other suppressors 'smoke' on the outside the first couple of times they get really hot, as they burn off oils. This is normal.
