New old stock Colt green recoil spring specifically for use with the Colt LMG buffer (not for use with regular AR carbine/rifle buffers). This is slightly shorter than your standard rifle buffer spring, and when combined with the proprietary Colt LMG buffer, reduces the cyclic rate to a smooth, controllable 600-700 rpm. This is unused and was stored uncompressed and is in perfect condition, no kinks or stretching.

Asking what I paid, $70 shipped.
