Extra Power 5-Coil Extractor Spring Upgrade Kit
A five coil extractor spring kit for AR-15 bolt carrier groups, delivering higher than OEM tension. Includes the spring, a mil-spec insert, and a Viton O-ring.
Why More Tension
The extractor has to hold the case rim through the entire extraction cycle. On a shorter barrel the pressure is higher when the bolt starts to unlock, and the carrier is moving faster, which gives a factory spring less margin than it has on a 20 inch rifle.
This kit raises extractor tension above OEM to keep that grip on rifles 16 inches and shorter.
The Spring
Chrome silicon wire stock, heat treated, stress relieved, and cryogenically treated. Same material and process as Sprinco's buffer springs.
While you have the bolt apart, gas rings are the other wear item worth replacing at the same time.
Doing more than one rifle? The same kit is available as a 3 pack.
