Aero Precision Nickel Boron 308 AR Bolt Carrier Group
There are a couple simple reasons to utilize a Nickel Boron 308 AR Bolt Carrier Group in your 308AR and AR-10 rifles. The Nickel Boron Coating by FailZero is super slippery this means the bolt carrier group can operate with much less lubricant, the bolt carrier group will be easier to clean and the coating should allow the bolt carrier group to outlast the weapon under normal operating conditions. Less wear will also occur in the upper receiver. The finish also looks pretty slick.
Drop-in bolt and carrier group has a self-lubricating surface that eliminates the need to apply oil or grease that can attract dirt, dust, unburned powder, and carbon and lead to cycling failures. Proprietary EXO-treated Nickel Boron finish produces an exceptionally hard surface that’s 40% more wear resistant than chrome plating, with an ultra-low friction coefficient. Surface is actually harder than the substrate underneath and will not peel, flake, gall, or rub off. EXO-treated Nickel Boron finish bolt/carrier groups have been tested to function reliably without additional lubrication up to 50,000 rounds. Reduced friction also means less heat generated by metal-on-metal contact, so the gun runs cooler and parts last longer. Easy to clean, too—fouling brushes right off. Before treatment, parts are shot peened for surface uniformity and magnetic particle inspected to make sure there are no hidden flaws. Gas key is hardened to USGI specs, chrome lined to resist erosion, and comes already staked to the carrier.

I just saw this at Brownells. A .338 Federal Marked Stripped Lower for $109. This can be used for a 308AR and is a great price.
338 Federal 308AR Stripped Lower Receiver – Rugged, fully machined 338 lower is ready to be the foundation of a hard-hitting long-range tactical, competition, or hunting rifle built to meet your exact specifications. Precision milled from a solid billet of high-grade 7029 T6 aluminum, with extra metal in the right places to handle thousands of rounds of full-power ammo without flexing or stress-cracking. Mil-spec hardcoat anodized for extra surface strength and corrosion resistance. Beveled mag well aids in fast reloads, and the integral, straight triggerguard milled from the billet with the rest of the receiver provides clearance for a gloved trigger finger while adding to the structural strength of the receiver.
Accepts standard 308-AR upper receivers & components.
Midwest Industries has recently announced the addition of a .308 AR rifle line to their existing selection of quality production firearms. The MI-10 is currently available with a 16” barrel configuration, but plans are currently in the works to add an 18” and 20” model.
The new MI-10 will incorporate a Criterion-manufactured 416R stainless steel barrel with a salt bath nitride surface finish for extended barrel life and added corrosion resistance. 16” and 18” variants will feature a 1-10 twist, while the 20” model will come standard with a 1-11 twist rate. Each rifle will feature CBI’s M118 LR chamber, giving shooters the option to use both .308 Win and 7.62×51 NATO ammunition. The M118 LR chamber incorporates a slightly longer throat than the SAAMI .308 Win design, allowing shooters to effectively run loads with heavier bullet weights.
Weighing in at a respectable 8.5 lbs unloaded, the MI-10 features Magpul furniture and a Midwest Industries floated handguard. The MSRP for these rifles is listed at $1,699, but they will be available for purchase from Midwest at an introductory rate of $1,599. A small selection of the 16” MI-10 rifles are currently available for local purchase from the Midwest Industries Waukesha showroom. The full web release is still pending, but the rifles should be available for purchase from www.midwestindustriesinc.com shortly.
The Brownells 308AR Barrel Extension Torque Tool has a very misleading name. In fact my first impression after reading the title lead me to believe the 308AR Barrel Extension Torque Tool was for tightening the barrel extension to the barrel. THAT IS NOT THE CASE. This tool is for preventing damage to your upper receiver when tightening the barrel nut.
Handy tool aids in applying straight-line torque for fast, easy installation of the barrel nut without scratching the exterior of the upper receiver. Helps ensure the right amount of torque is evenly applied, while maintaining proper alignment of the barrel, upper receiver, and gas tube ports. Use with any barrel nut wrench or free-float tube wrench and a torque wrench with a ½” square drive. Simply clamp the barrel nut wrench handle firmly in a bench vise, insert the barrel into the upper receiver, and finger tighten the barrel nut. Slide the barrel through the wrench, insert the Torque Tool in the back of the receiver until the teeth lock into the locking lugs in the barrel extension, and apply torque with the torque drive through the Tool to tighten the barrel nut. Precision machined from heavy-duty steel bar stock for years of reliable service. Available for the 308 AR.
Since the beginning of the 30AR platform push in 2007 with the forum at 308AR.com members and visitors have been trying to get their hands on a CARBON FIBER WRAPPED 308AR BARREL. Many have paid money and got on waiting lists never to receive their CARBON FIBER WRAPPED 308AR BARREL. Others after over a year wait received inferior products in return for their patience. Well today I was updating the websites with info on our newest advertiser CRITERION BARRELS INC and I wanted to see what Brownells was offering for the CBI branded product. Imagine my surprise to find that in stock at Brownells is a CARBON FIBER WRAPPED 308AR BARREL from Christensen Arms. I have no info other than what’s on the respective websites but I did email some questions of to Christensen Arms. Check this barrel as well as it’s AR15 sibling out for yourself at Brownells.

The ambidextrous AXTS Raptor Charging Handle is all the rage these days with shooters whether for the AR15 or DPMS LR-308/SR-25 based weapon platforms. While the MechArmor TacOps-1 is still my “Go To” ambidextrous charging handle based on simplicity and strength it’s hard not to be attracted to how cool the Raptor looks installed on your favorite AR15 or DPMS LR-308/SR-25 based weapon. I have on of each model on order at Brownells. I will photograph and review upon their arrival.

Just as Connecticut proposed the most draconian gun laws in the nation I managed to locate and purchase an Armalite AR-10 A4 or to be more specific an AR10A4 10A4CF-2. The AR10A4 10A4CF-2 is essentially a Connecticut legal (as of February 2013) Armalite AR10A4 Carbine with pinned stock, welded and pinned muzzle device in Armalite green. The AR10A4 10A4CF-2 utilizes Armalite proprietary magazines. Naturally this rifle will turn into an upgrade project withing my now legal limits. Note: The magazine displayed in the rifle is an Armalite factory 25 rounder. In reality the magazine is not as long as it appears. In my excitement I did not fully seat the magazine.
Model: AR-10 A4 Carbine with Green or Black Furniture
Caliber: .308/7.62 X 51mm NATO, 4140 steel
Barrel: 16″ Double Lapped, Chrome Lined
