Changing stock-why should I change the buffer?

[doninva]

I am going to change my stock on my ar. Is there any advantage to changing my DPMS buffer and spring. Thanks, Don

I don't think so unless you find some performance issue or are going from a carbine length tube to a rifle length, though I don't have any experience on this.  I have several ARs and change out parts often but never a spring/buffer.

Thanks, I am just going to change my stock DPMS for something with a little better cheek weld. Was hoping I didn't need to change anything else. Don

Colt started using heavier buffers in carbine models to reduce the cyclic rate a little bit. I'm assuming it also helps reduce felt recoil a little, as well. Like drdougrx said - only reason to change it is if you're having some issues with function. I run carbine buffers in everything, regardless of barrel length, and I don't have any issues.
