Nearly two decades of building the finest custom tactical AR-15 rifles have given us the insight to develop a comprehensive line of stainless steel, match grade barrels that offer superior accuracy, reliability and longevity for your next custom AR rifle project.
All Wilson Combat Match Grade AR-15 barrels are precisely crafted of the finest American-made 416R rifle rated steel on computer controlled equipment to our exacting list of technical specifications. These proven barrels feature a hand-polished bore and feedramps and then complete a rigorous final inspection process that ensures your new barrel will meet your most demanding expectations. All barrels feature crisp CNC markings, precision muzzle crown and a chamber and gas port optimized for reliability.
The 7.62×40 WT is based on the inexpensive and readily available 5.56×45 Nato cartridge case. The 5.56 case is shortened to 1.560” and then re-sized (single operation) in a standard 7.62×40 WT sizing die which results in a formed 7.62×40 WT case with a finished overall case length of 1.565”. The cartridge is designed for 110-150gr .308” diameter bullets loaded to supersonic velocities, but if chambered in a 1-8 twist barrel is also suitable for heavy bullet subsonic use also. The 7.62×40 WT was designed around an optimal overall cartridge length of 2.250” which is a perfect fit in the new Lancer L5 AWM magazine and allows for proper case neck to bullet fit. Therefore the barrel throat was optimized for this overall length and the 7.62×40 WT does not suffer from the same inconsistent accuracy issues in the AR platform often seen with the 300 Whisper and 300 BLACKOUT. The 7.62×40 WT only requires one unique component, the barrel to build. All other standard AR platform 5.56 caliber components are compatible. The 7.62×40 WT will function reliably with standard unmodified Lancer L5 magazines if downloaded to 17 or 24 rounds or Wilson Combat has modified Lancer L5 AWM magazines with 18/19 or 28/29 round capacity available that function ultra reliable. Wilson Combat would like to express our gratitude to Kurt Buchert for all his early development work on this cartridge.
