This longer Ed Brown barrel is specially designed for use with suppressors, with a thread size of 0.578 x 28 tpi RH. It includes a link, link pin, bushing, and thread protector, and is identical to the standard drop-in Ed Brown barrel. To ensure accuracy, Ed Brown Products uses high-quality materials and manufacturing methods. Their barrels are made from T-416 modified, gun barrel quality stainless steel bar stock and are precision machine cut from a 3 pound chunk bar of this top quality steel. The barrels are stress-relieved and heat-treated prior to final rifling and refinishing for superior accuracy. Ed Brown barrels are rifled by precision broach in the original six lands and grooves, one turn in sixteen, left hand twist as designed by John Browning.

In addition, Ed Brown barrels are heat-treated by an aerospace certified heat treat facility and sub-zero frozen for maximum strength and stress relief to ensure accuracy and longer barrel life. The dimensions of the outside of the barrel have been cut to max tolerance, which means less fitting work for the shooter and more accuracy.

A suppressor equipped with a Nielsen device (such as 276-000-055) is REQUIRED for reliability in a 1911. This device is also known as a booster, kicker, or Linear Inertial Decoupler.
