What is bolt carrier group coating? 🤔
It is a protective finish that prevents oxidation and wears on the BCG of your rifle or pistol. It helps to keep moving parts lubricated, thereby improving their performance and overall life span. There are several different types of coatings available, each with its specific benefits.
Bolt carrier group (BCG) coatings are an essential part of any firearm, providing protection from the elements and ensuring optimal performance. The type of coating you choose for your BCG can have a significant impact on the durability and reliability of the firearm. There are a variety of features that need to be taken into:
- 🔶 The most important feature is corrosion protection, which helps protect the BCG from rust and other corrosive elements that can damage the firearm.
- 🔶 Additionally, some coatings provide lubricity, which reduces friction between moving parts and minimizes wear and tear on your firearm.
➡️ Other features include:
- 🔶 Hardness, which makes your firearm more durable;
- 🔶 Adhesion strength, which ensures the coating remains firmly attached to the metal surface;
- 🔶 Impact resistance, which prevents chipping or cracking;
- 🔶 Abrasion resistance, which helps prevent scratches and scuffs;
- 🔶 Chemical resistance for protection against cleaners and solvents;
- 🔶 Heat resistance for protection against extreme temperatures and thermal conductivity for improved accuracy.
- ❇️ Bolt carrier group (BCG) coating is a form of protective coating applied to the BCG’s surface that offers superior protection against wear and tear.
- ❇️ The coating also reduces friction and improves functioning, helping to ensure smooth and reliable operation with every shot.
- ❇️ It can also help improve accuracy by reducing group-to-group variation in velocities and pressures when firing multiple rounds through different rifles and barrels.
- ❇️ The added lubricity provided by coating can also reduce stress on other parts of your firearm as well as make them easier to clean.
- ❇️ By reducing the amount of fouling that accumulates inside the firearm during shooting sessions, can increase overall performance and efficiency while decreasing cleaning time.
⚙️How does it work?⚙️
Bolt carrier groups (BCGs) are the core components of an AR-15, and they serve a critical role in maintaining proper functioning.
🛠️ A BCG is composed of several key parts: the bolt, the carrier, the gas rings, and the firing pin.
👍 When assembled correctly, these components work together to cycle rounds through your rifle, allowing it to fire accurately and reliably.
➡️ The most common type of BCG coating is phosphate, which is applied to steel parts using electrochemical processes like anodizing or chemical bath deposition. Phosphate creates a hard surface that helps resist rust and abrasion while providing some lubricity properties.

I’ve spent a lot of time researching the various finishes for BCGs, but it seems like everyone has a different opinion on what’s best. I’m drawn to the idea of a fully chromed BCG because it would be so easy to clean. However, the cost of that kind of finish might make me reconsider. I’m curious to hear your thoughts. Do you have a preferred finish for BCGs? Would you recommend going for a fully chromed BCG, or is that just a waste of money?
As an AR-15 owner, I have a standard Parkerized bolt carrier that’s chrome lined, and I’m pretty satisfied with it. Cleaning it isn’t too bad, although I know it would be even easier with a fully chromed bolt carrier. If the price difference between the two finishes is less than $30, then it might be worth going for the chromed option for the convenience of easier cleaning. However, if it’s more than that, I don’t think the extra cost is worth it unless you value the aesthetics of a fully chromed bolt carrier.
In my opinion, a fully chromed bolt carrier is the best option for my budget and cleaning preferences. However, it’s worth considering that there may be additional quality differences between fancy coated options, such as shot peening, steel grade, key staking, tolerances, and Loctite.
Based on my personal experience, I have found that a chromed BCG is significantly easier to clean compared to a standard one. This is especially true when I shoot suppressed. Therefore, I believe that the extra cost of a chromed BCG is worth it. However, I cannot speak to the merits of NiB or EXO coatings as I have no personal experience with them.
I’m new to the world of high-end AR-15s and looking for advice on the best bolt carrier group (BCG) to get. Which brands should I consider?
I have a Lantac Enhanced Full Auto Style Bolt Carrier Group and I’m really happy with it. As for handguards, I recommend Durkin Tactical’s options. I’ve used them before and haven’t encountered any problems.
I’m having an issue where the bolt on my AR-15 doesn’t stay locked back, regardless of whether the magazine is empty or dropped out. I’ve tried using both PMags and USGI mags, but neither seems to work. I want to be able to use my bad lever, but it doesn’t seem to be the cause of the issue.
It’s possible that the problem lies with my magazine or that my bolt catch is out of spec and needs to be replaced with a new or aftermarket one. Another possibility is that it could be a buffer problem unrelated to the bad lever. Before I take any further action, need to figure out if it’s a problem with the rifle’s function or if it’s related to the installation of the bad lever.
Based on my personal experience, I had a similar issue with my rifle where the bolt wouldn’t lock back. However, I was able to fix it by applying some oil around the area where the bolt catch is located, including the crevices. This solved the problem for me and my rifle now locks back without any issues.
If you’re having trouble with your bolt not staying locked back, try manually engaging the bolt catch by pulling back on the charging handle and pushing the bottom of the latch in. If it still doesn’t catch that way, you may have an out-of-spec bolt catch or receiver, or you may have installed the bolt catch incorrectly. On the other hand, if it does lock back manually, your gun is likely under-gassed.
I’m experiencing the same issue with my AR-15. After some investigation, I believe the problem lies with the spring in the bolt release. I installed a B.A.D. lever and the added weight, along with a spring that is the wrong size, is preventing the bolt catch from being held up by the spring in the magazine on the last round. I’ve tested this with different magazines and ammo loads and it happens consistently. My rifle is chambered in 6.8 SPC. Fortunately, adjusting the bolt release isn’t too difficult, but it’s important to be careful when working with small parts like detents and springs to avoid losing them.
