Identical to the Ed Brown drop-in barrel, but longer length and threaded for use with suppressors. Thread size is 0.578 x 28 tpi RH on the 45 ACP barrels. Includes link, link pin, bushing and thread protector.
A suppressor equipped with a Nielsen device is REQUIRED for reliability in a 1911 device. This is also referred to as a booster, kicker, or Linear Inertial Decoupler. We use and recommend the Black Reign suppressor by Elite Iron.
