Brownells BRN-4® HK® 416 compatible barrels, now with chrome bore and chamber
Historically extremely hard to procure, HK® 416 compatible barrels are now available as part of the BRN-4 lineup.Available in barrel lengths of 10.4, 13.7 and 16 inch, these barrels are suitable for any need. Machined by Faxon, these barrels fit BRN-4 upper receivers and early generations of HK® 416 upper receivers and components. They are the perfect fit with the BRN-4 bolt carrier group and gas block (search “BRN-4” for all parts).
Chrome lined bore and chamber of these barrels has been the go-to for hard use rifle barrels for decades, and you will be extremely pleased with the smooth and crisp application by Faxon in these bores.The chrome is well applied, and just extends over the crown of the barrel and the edge of the chamber.Barrels are button rifled from 4150 chrome moly steel, the top choice for hard use barrels, with a 1-7 twist and have commonly used ½-28 muzzle threads for the attachment of the muzzle device of your choice. A matte black phosphate provides a corrosion resistant exterior.
