SilencerCo 3-Lug Muzzle Device Black with .578"x28 Threads for 45 ACP AC2605

SilencerCo 3-Lug Barrel Adapter The 9mm SilencerCo 3-Lug barrel adapters are designed around the iconic HK standard. They are compatible with 3-lug mounts made to common industry specifications, including both the original SilencerCo 3-Lug Mount and the newer Low Profile 3-Lug Mount. The 1/2x28 9mm version adds roughly .8" to the barrel, and has an overall length of 1.4." The 5/8x24 variants for both 9mm and 45 are 2.3" in length adding 1.9" to the end of the barrel. Additionally, the 5/8x24 variants have wrench flats for ease of installation. SilencerCo has designed the 5/8x24 (45) AND 9/16X24 (40) variants specifically around the B&T APC45 3-Lug barrel and as such may not be compatible with non-standard 45 3-Lug mounts.
