Rifle vs Carbine buffers

[benmacksh]

Hi all, I've been looking around the internet for a solution to my dilemma. Basically, I want to use a buttstock that requires a carbine length buffer tube on my AR15. However, I'm going to be using a 20" barrel with a rifle length D.I. gas system.

Will a standard carbine buffer work for this setup, or will a heavier carbine buffer possibly be required?

The buffer is dependent on the stock, not the barrel. The carbine buffer in a collapsible stock will work fine with a 20" barrel.

The heavier carbine buffers are to dampen the faster cycling speed of a short gas system. Since you are using a rifle length gas system, it will generate less thrust than the carbine length gas system, so you should be fine with the standard carbine buffer.

What he said. The C7A2 would be the best example of this.
