The FLY 45 has industry leading .45 ACP suppression performance while being 25- to 50-percent lighter than its competitors. It\'s also super tough and is rated for .45-70, .308 WIN, and .223/556 (see below for barrel length restrictions). The FLY 45 is a modular suppressor with a full length (including booster) of 8.85 inches and a short configuration (with booster) of 6.6 inches. We have all the data posted in the large table below, but it\'s easy to summarize-- The FLY 45 suppresses better or the same as the other quietest .45/.46 caliber suppressors on the market, but it\'s a lot lighter and tougher. The FLY 45 ships with a .578-28 piston and the booster basket (which adapts the booster threads to HUB). For high temperature durability, we are using specially-made 17-7 wave springs in the booster. It is compatible with the Rugged/Griffin/SilencerCo/TBAC standard pistons. You can remove the booster and booster basket assembly and you\'re left with an industry-standard 1.375x24 \"HUB\" rear mount. This allows use on any compatible HUB mounting system. We also have a \"CB2HUB\" adapter to fit on our CB muzzle devices.
