FAQ

Is 6.5 Grendel a good choice for long-range shooting?
Yes, thanks to its low-recoil and high-accuracy, it’s suitable for shooting at a distance from 200 to 800 yards. This is a great way to make your AR-15 rifle a hunting gun.
How does the bolt carrier group work?
It uses the gas after the round is fired. The gas key is connected with a gas port, it passes all the gas into the BCG’s body. Then, BCG drives back into the buffer, making the buffer and the spring compressed, after which the spring quickly re-expends, forcing the BCG into the starting position. The spent casing ejects to allow a new round to chamber. The entire process takes only a moment.
Do I need to maintain the BCG?
Although bolt carrier groups are very durable and can last forever, thanks to the solid materials and great coating, it’s important to clean the bolt assembly area to prevent malfunctions.
Is it necessary to change the BCG?
Factory-new rifles are good and well-designed, but they are not individually customized. If you want to have a firearm that will meet all your preferences, you will have to change the lower receiver and the upper receiver.
