Details:

Are you ready to move up to a smooth-running AR? Well, there are a few things you need to put into motion. An adjustable gas block, the correct buffer, and a low mass BCG will make that happen for you. You can have this without giving up quality if you choose the right parts. While there are many decent manufacturers, F1 is well known to pack a ton of quality into everything they create.

All or None

First, you shold stick with an M16 style BCG. Additionally, you want one that is thoroughly tested through the MPI and HPT process. Now, some lower-quality BCGs claim this. However, some of them are only batch tested. There may be 10 or 10,000 parts in a batch. This shortcoming is not the case with F1 Firearms. Every lightweight bolt carrier group made by F1 ships gets quality checked inside and out. When you choose F1, you get a high-quality, full-featured lightweight bolt carrier group.

Try to Keep Up

The main thing that affects recoil is how much weight, or mass, cycling inside your weapon. An F1 Firearms lightweight bolt carrier group puts less weight inside your gun. Less mass equals less felt recoil. A low mass BCG is designed to work with a properly tuned rifle. There's something special about firing a weapon that runs so smooth. It's like music. The gun seems like it becomes a part of your body. I know, skill plays a significant role in speed. But, a well-tuned rifle with a low mass BCG, breeds efficiency and therefore speed. When you have excellent equipment that matches your talent, you almost think your rounds into the target.
