RPD44 7.62x39 BARREL, NITRIDE COATED W/ EXTRACTOR CUT

Product Details

We just added a small quantity to inventory. These were from our last batch that were put aside with gunshow inventory. Another run is in the works!

U.S. made replacement RPD barrel. CNC machined from ER Shaw 4140 Chro-moly blank.  Press fit .940 diameter barrel shank for use with all major brands of Semi-Auto RPD receivers on the market. Our barrels feature pre-cut extractor clearance for simplified installation not requiring a milling machine.  Barrels are nitride finished inside and out for corrosion resistance and superior barrel life.  See comments below regarding nitride finishing for further information. May require gunsmith adjustments to headspace and gas system components due to wide variety of kits on the market. 

Salt Bath Nitride finishing (or Melonite or QPQ as it’s called) is an EXTREMELY hard, corrosion resistant coating used on barrels to provide long life, corrosion resistance, and enhance accuracy over other processes.  Unlike chrome lined barrels, nitride barrels exhibit barrel lives running upwards of 10,000 rounds.  Due to the nature of the chrome lining process, the chrome layer is deposited in uneven thickness down the bore of the barrel; this causes many of the accuracy issues that many Com-block guns are known for.  By using a nitride process, the barrel surface actually becomes hardened and there is no change dimensionally to the bore and chamber, enhancing accuracy over a chrome lined barrel.  Nitriding also has been shown to exhibit advantages over chrome lining as far as corrosion resistance is concerned as well.
