One day, when we all have to grow up, there are choices to be made. Diet, exercise, and lifestyle must be changed if we want to continue living. Some choices have a great impact on our lives, even if we don’t see it at the time. While your cholesterol levels impact your health, the .308 buffer system you select impacts your life at the range. Indeed, to myself, one is just as important as the other.

Perfect Balance

Certainly, the .308 recoil spring hiding inside your buffer tube won’t help you live forever. However, it will make your life better while you’re living it.

Therefore, your time behind the trigger becomes more of a pleasure than a beating. They combine the perfect .308 recoil spring with the right buffer system to give you results that you can only read about. You will experience the difference that Armaspec quality delivers with only the click of a mouse.

Everything You Know Is Wrong

This .308 buffer system produced by Armaspec is an exact match for your AR, you get to enjoy Mil-Spec compatibility with custom results. When you get a new buffer system form Armaspec you get consistency, without excessive wear, wrapped up in a single component that delivers without fail.
