A Brief Introduction of 9mm Bolt Carrier Group
Strictly speaking, the bolt carrier group is well-thought-out as the heart of your 9mm. As a matter of fact, it’s the heart of any firearm. Think of it similar to an engine for your car. Without the engine, you cannot drive your car.
Without a BCG, you cannot use your 9mm. Simple as that. A BCG includes some key components that will work in unification with your 9mm’s firing ability. We will go a little deeper into what encompasses a BCG in the next section.
The Components of a 9mm BCG
There are nearly a dozen components that include a bolt carrier group. Most of these are your pins and springs that will grip it all together. Of course, we cannot forget some of the key components as well. A BCG will include some of the following key components: the bolt itself, ejector, bolt carrier, extractor, and the firing pin.
How to Choose a 9mm Bolt Carrier Group
Knowing what to search for in a BCG is important. You’ll want to make sure that all the parts are complete and are ready for use as soon as you’ve received them through shipping. You should also know some of the supplementary characteristics and aspects of each bolt carrier group. Therefore, you know whether or not it requires any additional parts or if it’s simply ready to drop in and be installed. Here’s what you need to look for:
Not every AR-15 9mm owner will have skilled gunsmith skills, and we can understand. So we do our best to find some of the best BCGs that are easy to install and won’t need the services of a gunsmith for a suitable install. All it takes is a few minutes and the right kind of tools. Once installed, you’ll be able to give it a test drive at the range to make sure that it’s functioning properly.
Price is perchance one of the most important aspects of a budget shopper to consider for the best 9mm bolt carrier group. Especially when they are looking for something that is high in quality. As you’re looking for a BCG, look for one that is the best in quality but can fit somewhere in your desired budget. Even if you’ll be spending an amount that’s high on your firing pin budget range for the best 9mm bolt carrier group, it’s a lot better than buying an ineffective BCG just because of the cheap AR9 gas key price tag.
Is Everything Intact?
If the answer is yes, then that’s your green light to go ahead in purchasing it. You should have all the parts you need to ensure that the BCG 9mm bolt carrier group works properly and is ready to be installed. Missing parts can cause quite a catastrophe (and obviously won’t allow the BCG 9mm bolt carrier group itself to work).
The best 9mm bolt carrier group is heavily reliant on their coating but there’re many types of coatings available.
Nitride coating is the most popular choice of coating, a type of chemical treatment that hardens the surface. Hence, nitride coating allows the resistance against corrosion.
Hard chrome is a durable and reliable coating but it is often difficult to apply. Hence, many bolt carrier group manufacturers on the market sway away from producing hard chrome. However, if you can get your hands on hard chrome coating then you’d sure to enjoy it as it is easy to clean and has resistance against corrosion.
Nickel Boron consists of 95% Nickel and 5% Boron. Nickel Boron allows great and sleek aesthetics which are also resistant against corrosion. However, Nickel Boron is subjected to natural wear and tear so be sure to handle your Nickle Boron with care.
Essentially, this is the upgraded version of Nickel Boron as it comes with polytetrafluoroethylene by the brand, Teflon. However, the downside of polytetrafluoroethylene is that it is more harmful to the environment and will also be subjected to natural wear and tear like Nickel Boron
This is the “mil-spec” coating (for M4s) which is durable, cheap and good. However, it is very rough in texture and difficult to clean.
Vapor Deposition Coatings (TiN, PVD, CVD)
To avoid confusion, they’re each an individual coating and aren’t the same. The most common is Titanium Nitride (TiN) while PVD and CVD are processed to apply allow on bolt carrier groups. The downside of these coatings are that they’re not cheap.
