Things to consider for selecting the best bolt carrier group
It can be daunting to pick the right BCG for your rifle. And truly speaking, there are not many things that can be counted as considerations. The material, finish, profiles, testing, etc. are to be the reasonable things when it comes to getting one. I have listed some things to consider which I found the great help for buying a right bolt carrier group. Check the guide below:
- As the BCG will be facing a lot of stress and heat, the material should be of a standard quality. It should have the reliability, strength, and durability.
- The next thing is the finish it has and the linings made on it. These things help to protect the BCG from corrosion and abrasions. They also improve the reliability, reduce friction, make the cleaning process easy, and make the parts slicker.
- See the profile of the BCG, whether it is semi-automatic or fully-automatic. The full-auto BCG can also work on semi-auto rifles. So know your rifle and select the profile that matches with it.
- The two methods which measure the standard of the BCG are the HPT (High-Pressure Testing) and MPI (Magnetic Particle Inspection). If you find that the BCG is not having these tests done, then don’t buy it.
Bolt carriers provide reduced frictions and lower the operating temperature of your weapon. This results in an overall good performance of your equipment in all types of weather conditions and climate changes. If you ask for the best AR15 bolt carrier group, then I will recommend going for the Brownells BCG as it will be the heart of your AR15 rifle without breaking your bank. As not the best for me can be the best for you always, so check out the products and get your perfect match. There are some alternatives of a titanium bolt carrier group available in the market, but the top-quality BCG is what you should get for clean maintenance of your weapon. And the above list will help you get the value for the money bolt carrier group.
