I’m definitely going to have to pick up a few of these new NIB EXO BCG’s from AIM Surplus. The NIB EXO coating is simply amazing and well worth the extra money over a standard NIB finish. Combine the NIB EXO finish with the awesome specs of this BCG and this should be a real winner. I already have a few AIM Surplus BCG’s and they do a great job of offering a high quality product at a very good price point. This new BCG is made right here in the USA with a Lifetime Warranty and just $119.95 shipped.

We are having these bolts manufactured to our exacting standards with no Frills added to be able to offer the best BCG at the Best Price. Features 9310 Bolt Material; 8620 carrier and gas key; Properly staked Investment cast gas key hardened to USGI specifications fastened with Hardened Grade 8 Fasteners; Shot peened MPI (Magnetic Particle Inspected) Bolt. Extractor insert installed. Proudly made in the USA with a Lifetime Warranty.

UCT’S EXCLUSIVE EXO TECHNOLOGY
EXO Technology creates a competitive advantage for all kinds of components, because treated parts run dramatically longer and more accurately with less maintenance. Further, EXO greatly enhances heat dissipation, so treated products run far cooler than non-treated parts. The EXO process is permanent, lasting for the entire lifespan of treated parts. A patented, nodular nickel-boron (NiB) surface treatment, EXO nucleates on the surface atoms of metals, becoming part of the metal rather than merely applied to the outside. In addition, the treated surface becomes harder than the substrate itself, eliminating the cost, weight and degradation problems of conventional hardened metals. EXO Technology is featured in firearms, weapons and support systems used by the U.S. military and law enforcement and security agencies. EXO Technology is appropriate for virtually any application where reduced friction, extended service life, enhanced performance and lower maintenance are desirable.

Especially when you start looking at special coatings like Nickel Boron, etc. AIM Surplus just released a great looking Light Weight Nickel Boron BCG that totally breaks the rules by coming in at just 8.5 ounces (almost 28% lighter than their standard BCG) with a price tag of just $120 and Free Shipping.

Assembly
The requirements for assembly of our Bolt Carrier Groups are much higher than most. Before assembling the gas key to the carrier, permatex NO.3D aviation is applied to form-a-gasket around the gas hole (per MIL-SPEC). Then Grade-8 hardware is used to attach the gas key, followed by properly staking per spec. When installing the extractor to the bolt, a crane-o-ring is inserted with the spring to insure proper ejection. Then high temperature grease is applied to the gas rings before inserting the bolt into the carrier, which allows for much smoother operation. These BCGs are inspected to the highest of standards, to insure a high quality product that is 100% reliable for our customer… PROUDLY MADE IN THE USA!

AIM Surplus just introduced their new Black Nitride AR15 Bolt made from Carpenter 158 steel. The bolts are also Shot Peened and MPI (Magnetic Particle Inspected) and feature Billet Machined Extractors with Black Insert and O-Ring upgrade. Black Nitride is quickly becoming the go-to finish for AR parts. The fact that it is a Surface Treatment (Molten Salt Bath) and not a coating gives it better durability and boasts some of the best lubricity and corrosion protection of any finish out there. If you’re building a BCG or need a great backup/replacement Bolt, this is a great option for just $49.95 with FREE SHIPPING at www.AIMSurplus.com.

Aim Surplus Black Nitride V2 Bolt

The last year has seen an explosion of interest in building big bore AR’s, especially the AR-10/.308. Things like .308 receiver sets and barrels are not only a lot more readily available but also much more affordable than they ever have been before. Unfortunately some smaller parts like Bolt Carrier Groups are still not so easy to find and can cost quite a bit. This weekend I happened to run across the AIM Surplus Nickel Boron .308/7.62×51 BCG and was surprised to see that not only does it look like a very high quality BCG but they are selling it for just $179.95 with FREE SHIPPING in the lower 48 States. I just finished up my second .308 build over the weekend and might need to pick up one of these BCGs for the next .308 build.

The Bolt is shot peened and manufactured out of 9310 Tool Steel with a 4140 Machined Extractor.

The Gas Key is Hardened to USGI Specifications and fastened to the carrier using Grade 8 Hardware, and then properly staked. More information below.

The AIM Surplus Black Nitride BCG is definitely one of the nicest BCG’s I own. I’ve been using one for I think about 4 months now with absolutely zero issues. It features an 8620 enhanced carrier, a Billet Machined 4140 Gas Key and the entire BCG is coated inside and out in Black Nitride. Black Nitride is very slick and easy to clean but is much more durable than most other BCG coatings. I have the original version of this BCG which had a 9310 Bolt. This new v2 BCG has been upgraded with a C158 bolt which is something I know a lot of people are pretty picky about. AIM Surplus just received a new shipment of these at an unbeatable deal. While they are still in-stock they are just $99.95 with FREE SHIPPING in the lower 48 States. Purchase one (or five 🙂 ) at www.AIMSurplus.com.
