AlphaWolf Barrel for Glock 21 .45 ACP Threaded .578 x 28 - Lone Wolf
Item #: LWAW2145TH
Lone Wolf AW-2145TH
Weight: 3.00 pounds
Alpha Wolf barrels from Lone Wolf Distributing establish the benchmark for absolute accuracy and combat reliability. It is the pinnacle of what every other barrel manufacturer strives to be. Proudly made in the USA.
This barrel is designed for Glock Model 21 chambered in .45 ACP. This barrel is threaded .758 x 28 and comes with the appropriate thread protector installed. It will fit all Glock generations. It is designed for lead, plated, or jacketed ammunition. It is constructed of certified, stress relieved 416 stainless steel.
The barrel has been button rifled and gone through three stages of honing. It has been coated with industry recognized SBN premium coating. Barrel is heat treated to RC 40-42, with the SBN coating it increases surface hardness to RC 60. Exacting tolerances allow for drop-in installation. Fluting creates path for heat and debris to escape.
Button rifling, the "button" is a tool made of tungsten carbide. The carbide button tool is attached to a rod of high tensile steel (barrel), and the other end of a long rod is attached to a special adaptor. An AC Servomotor rotates the button precisely to emulate twist rate, this forms the grooves on the inside of the barrel.
Rifling puts a lot of stress on the steel so it must be relieved, this is done by heating the barrel in a vacuum furnace with an inert atmosphere to 525-550 degrees Celsius, then slowly cooling it.
Honing is a stock removal process intended to perfect bore geometry and size by removing a minimal metal layer while generating a finish pattern to provide optimum lubricant retention. The hone process produces extremely tight tolerances in straightness, roundness, size, and surface finish of cylindrical bores.
SBN coating is Salt Bath Nitrate, which is like Tennifer. It increases hardness and wear resistance at part surfaces while cores remain softer and more ductile. By coating the barrels with SBN it increases the corrosion resistance and significantly reduces risk of distortion, while increasing surface hardness.
Fluting is done to reduce weight and increase rigidity for a given total weight or increase surface area to make the barrels less susceptible for overheating.
