If you own a .308 rifle you know that finding new parts can be difficult and time consuming. To complicate things not all .308/7.62×51 components are interchangeable which makes it even more difficult. Well, if you own a DPMS Pattern .308 AR you’re in luck. Harris Tactical is doing another pre-order, this time for the .308/7.62×51 NiB-X FA BCG for DPMS Pattern rifles. These should be ready in mid to late February so it wont be that long of a time to wait. You’ve got to get in on this soon though before the pre-order ends. Head on over the HarrisTactical.com to pre-order yours.
These .308 (DPMS Pattern) Bolt Carrier Groups feature NiB-X Nickel Boron Baked Coating, which provides extreme durability, performance, and reliability. The Nickel Boron coating is corrosion resistant and harder than Nickel Teflon, Melonite, or Hard Chrome with a hardness of RC 72. Cycling is smoother and debris and buildup can simply be wiped free.
Components included in the Assembly are mil-spec and manufactured by US suppliers. The Bolt assembly is case hardened, shot peened, magnetic particle inspected, and constructed of Carpenter 158 steel. The extractor includes a high performance spring and black buffer. The 308 style Carrier is machined from 8620 steel, heat treated, and case hardened. Attachment of the Gas Key is done with grade 8 hardened fasteners, which are staked per mil-specs. The Gas Key is sealed with the proper gasket as well.
SPECS: Fits .308 DPMS Patterned upper receivers.

Now you have an option to add the only lubricant/cleaner that sticks to Nickel Boron, which is FIRE Clean. This product is revolutionary on all moving metal surfaces, Direct impingement, suppressed and belt fed weapons. Works well on all surfaces and non-toxic. If you would like more than one bottle, type in “Fireclean” in the white search box to add more. You can also read more about it. Once you do and use it, you’ll never use anything else on your weapons.
