USED Rival Arms Threaded Conversion Barrel Compatible With Glock 22 9mm Lub RA-RA20G412A. The barrels are each individually hand inspected for accuracy. The barrels come with a low temperature vaccuum PVD coating which creates a durable barrier against wear and tear even in the harshest environments. The rifling is set for match-grade precision and 1:10 twist with 6 groove rifling. The borasic injection mending on the bores and heat treated sub-bores reduces friction and holds up under all conditions. Each barrel has its own specialized boreslice which cleans the bore as it heats up. This rinsing stops carbon and other build-ups that can cause accuracy issues. The rinsing process is also done thrice to ensure that the bores remain cool to the touch at all times. The rinsing process also extends the barrel's lifetime. For those looking to completely customize their Glock consider a Glock conversion barrel.
