16" Sig 556 Recoil Spring
I just got this Sig 556. Very well loved, but I spruced it up with some aftermarket parts. Decided to put in a new recoil spring in case the old one was worn out. I got a Wolff spring, but it is much longer than the original. It also isn't braided like the one that the gun came with. Is it supposed to be cut? What is the correct length?
