DPMS AR15 Extractor Spring Assembly AR-15 M16
While you're adding a MUST HAVE D-fender extractor ring, I recommend replacing your extractor spring with this high quality new spring and rubber insert. Now you're set!
Matches the original equipment specs to keep the extractor under the correct tension. Rubber insert gives stability to the spring and lengthens service life.
SPECS: Steel, 3/16" (4.7mm) long.
