Trigger Rebuild Spring Kit - Remington 870, 1100, 7600, and others

This kit comprises both a replacement hammer spring as well as five different trigger springs ranging in pull weight from 1.25 lbs to 5 lbs. The hammer spring is made from stainless steel, and the trigger springs are made from spring steel then plated for easy identification and to maximize corrosion resistance. This high-quality set of six springs fits nearly all Remington pump and semi-auto rifles and shotguns which use the trigger assembly as pictured. 

This kit allows you to restore your vintage Remington trigger to its original condition or it can be used to select your trigger pull weight preference based on the type of shooting you do. Aside from three lighter pull weights, the kit includes a factory-weight spring should you wish to bring your trigger back to original specification, as well as a heavier spring for cold climate shooting with heavy gloves. The new hammer spring will both correct light primer strikes due to an old or worn spring as well as correct/improve lock time, the proper function of both being crucial for maintaining accuracy. If unsure of compatibility please contact us first to check. Lumley measures the factory trigger at 4lbs (based on the Remington 7600 rifle), the ratings below can vary slightly when fitted to different firearms* and when installed correctly**.

NOTES

Although the springs provided in this kit have been designed and tested by Lumley to be safe, every trigger is different and it is imperative to ensure that your trigger is safe after installation. Lumley has come across some very unsafe 1lb springs for this trigger assembly which although break at the advertised pull weight, will slam fire when working the action hard or when dropping the firearm onto the buttpad. BE VIGILANT with all trigger modifications and test thoroughly after reassembly! In Lumley's testing, 1.25lbs is the minimum pull weight that this trigger assembly will achieve by replacing the spring and polishing the sear and hammer. By replacing the trigger spring alone you can expect 1.5lbs in an unmodified trigger assembly.

* Results may vary slightly between individual rifles and shotguns and are dependent on the trigger pull gauge, factory tolerances, and whether any other modifications have been done to the trigger. Lumley pull weight is measured using an RCBS gauge.

** We supply replacement springs only. If unsure about installation, we highly recommend having a qualified and competent gunsmith do the job. Slight variations between different rifles and shotguns may result in an unsafe trigger when fitting these springs. Always ensure the firearm is unloaded before commencing work and test the trigger function extensively upon reassembly whilst the rifle is unloaded. Slam closing the breech bolt and dropping the firearm onto the buttpad (both whilst unloaded) is imperative.
