The XP 5-Coil spring is stronger than OEM springs, eliminating the need for a D-Fender™ ring or CRANE Viton O-Rings.
Enhanced 4-Coil springs are ideal for 18"+ barrel lengths and those who reload, while the 5-Coil may be too strong for certain bolts or long barrels.
The springs maintain performance even under extreme duty cycles and temperatures up to 750°F, and the dual spring .308 set can be used with or without CRANE O-rings.
