Davidson Defense Premium  M16 Ar-15 Bolt Carrier Group

For 5.56 NATO .223 300 Blackout .25 Sharps
Made by Davidson Defense
100% in the USA


AR-15/M16 Davidson Defense Complete Melonite Nitride Bolt Carrier Group (BCG) is made of 9310 steel, nitride-treated, then MPI and HPT inspected for extreme safety.

This is one of the highest quality standard profile BCGs made. 

So what is the difference between this BCG and the others we carry?

This BCG has less machine marks; it’s made using much cleaner machining.

Additionally, every bolt head is HPT & MPI tested, not one out of 100 like most companies do. The finish is a real nitride matte finish.

The finish is uniform and holds the nitride properties throughout bolt carrier group.

Greatly increasing the life of the bolt carrier group.  

The carriers and the extractor are fully machined from billet stock for unfailing firing even up to 35,000 rounds without extractor change.

 So, what is Nitride Finish?

 Metal components treated with Nitride finishes have increased wear-resistance, fatigue strength, corrosion resistance, lubricity, and cosmetic appeal. Often replacing the processes of hard chrome or nickel plating, black nitride gives better corrosion protection at equivalent to chrome plated BCGs. Nitride treats the metal, so if the metal becomes worn, it’s still good. This contrasts with chrome plating; once gone or worn off, chrome plating is no longer effective. A nitride finish changes the metal, instead of just coating it with a thin layer of chrome. Additionally, products finished in black nitride clean up faster and better than phosphate standard BCGs.

Nice Suprise
The BCG is well built but does need a break-in with oil. I use Mobile One 0w-20. This BCG was so tight in 3 different rifles I almost sent it back. After oiling (the carrier) and manually charging 40+ rounds, it finally started sliding like silk. I would have gave it 5 stars but unusual to oil Nitride parts for a break-in. I did contact customer service and the response was almost immediate and offered a full refund if I was unsatisfied. You only get service like that when a company is dedicated to excellence.

3rd build with this BCG
Took build #1 to the range this past weekend. This BCG came well packaged and was "wet" and ready for immediate install. Dropped it into 2 different uppers and ran it through different versions of .223 and 5.56 from both US and foreign manufacturers. Impressed by the quality for the price paid. Just ordered 2 more to complete build 2 and 3.

Very slick bolt. Parts move freely out of the box. Gas key staking was superb and very clean. Excellent finish.

Performed Great
I used this in gun I built for grand daughter and it has worked great. So far no problems. The finish is nice. It worked good enough that I have a second ordered for my wifes build now that she decided she wanted a AR.
