Product Description The RIVAL ARMS RA20G102A Precision Drop-In Barrel is a match-grade upgrade engineered for Glock 17 Gen3 and Gen4 pistols chambered in 9mm Luger. Machined from premium 416R stainless steel, precision polished, and finished with a low-temperature vacuum PVD coating, this barrel delivers a durable barrier against wear and tear even in the harshest environments. The 4.49-inch fluted barrel features 6-groove rifling with a 1:10" twist for outstanding accuracy, while the BORSLICK Boron Nitride DCD (Dynamic Compound Deposition) inner bore treatment resists heat and carbon buildup, extending service life.
