Barrel – M10/9 9mm Stubby 1/2 x 28 Threaded Barrel


SKU: N/A Category:


This barrel is for the M10/9. It is 4-5/8″ in length and threaded 1/2-28 TPI – it’s also known commonly as a Stubby Barrel”.   This barrel is ideal for your suppressor or other barrel accessory threaded 1/2 x 28. It’s also the barrel we use on our Fat Ghost Upper Receivers.  It is made of CrMoV MIL-B-11595 material with 6 – groove, 1:10 twist and precision air gauged with inert gas vacuum stress relieved after button rifling process. The finishing is manganese phosphate, the traditional dark gray/almost black parkerizing of the MAC series guns . These were profiled on centers to provide accuracy between bore and profile which has been a problem we’ve experienced with other manufacturers’ barrels in the past. These will fit Full and Semi Auto M10/9 guns.  These are also sold with an optional thread protector.

NOTE:  We do NOT recommend shooting this barrel in full auto with the 1/2-28 threads exposed due to the thinness of the barrel wall at the 1/2-28 threads.  Repeated firing with exposed threads may cause the barrel wall to weaken and/or split.  We recommend always using shooting this barrel with a barrel accessory, such as a thread protector, flash hider, or suppressor firmly secured to the end of the barrel .
