What is the FN AMERICA LLC - AR-15/M16 5.56x45MM COLD HAMMER FORGED BARRELS?

With its more than 100-year legacy of exceptional barrel manufacturing, FNH USA has long perfected the cold hammer forging process to ensure accuracy and durability. These AR-15/M16 barrels are hammer forged using the same proprietary high-grade Chrome Moly Vanadium steel used in FN’s venerable machinegun barrels produced to handle the punishment of sustained fully-automatic fire. After forging, each barrel is Magnetic Particle tested to ensure that it is free of micro-stresses or flaws, resulting in consistency and quality in every barrel shipped from the factory. The bore and chamber are chrome lined to help resist corrosion and provide resistance to heat erosion which greatly improves barrel life and reliable chambering/extraction. The M4 style feed ramps and barrel extension provide reliable and consistent feeding and the matte black Manganese Phosphate finish resists external corrosion and oxidation. Currently available in a chambering of 5.56x45mm in 14.5” Carbine, 16” Carbine, 16” Mid-length, and 18” and 20” Rifle length gas systems, FNH USA Hammer Forged Barrels will provide you with a Distinct AdvantageTM, no matter your application. All models are .750 at the gas block.

Good value
Always like name brand products on sale. Had an FN lower needing and FN barrel. This is great for accuracy and the CHF tends to last for a long time. What else do you need.

Top Quality Barrel
I am very happy with this barrel. I am just a recreational shooter, but I was able to get a few nickel and dime size groups at the range using a Burris Fastfire 3. Granted, it is an indoor 25 yard range, but the nearest 100 yard range doesn't allow FMJ bullets so I don't have a lot of options to stretch the legs on this build. I digress. It is a very nice barrel; chrome-lined bore, parkerized exterior, FN stamp for peace of mind. Put about 200 rounds through it at the range with 0 issues and it held a tight group despite getting quite hot. Came well packaged, but oily as a bodybuilding competition, so a bit of cleaning is required.
