- ( 1 ) 13lb, 14lb,16lb, or 18lb ISMI Recoil Spring
- NDZ guide rod assemblies are made from solid stainless steel and help mitigate recoil during firing.
- Can be purchased as a guide rod alone or with your choice of included ISMI recoil springs in a variety of spring weights, as well as a convenient tuner pack that contains a guide rod and all of the available springs.
- The guide rod screw features a double Allen wrench design and is easily removable for maintenance, and comes in a variety of colors to customize the look of your firearm.
- All NDZ Performance parts include a lifetime warranty against manufactured defects.
- Proudly made in the USA.
We recommend the use of Blue Loctite on the hex screw threads when switching out springs. This will provide a firm hold and still allow easy removal when necessary.
ISMI Recoil Guide Rod Springs
ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability.
ISMI Recoil springs are the best direct replacement for OEM springs.
Independent tests reveal ISMI recoil springs have endured in excess of 100,000 compression cycles! ISMI springs include a 12 month manufacturer replacement warranty; however, we advise you practice routine maintenance and change your recoil spring yearly.
What Recoil Spring Weight do you need?
- 11 - 13 lb: For Competition Shooting, or use with a Recoil Compensator
- Lightweight spring: Faster recoil time, better target re-acquisition
- 14 - 16 lb: For Reduced Power Ammunition Loads
- 17 - 18 lb: Sig Factory Weight Recoil Springs
- 19 - 24 lb: For Heavy Power Ammunition Loads +p or +p+
- Please ensure you're using the correct loads for the spring selected to avoid cycling issues.
