If you want precision-calibrated springs to give your JP-15 rifle trigger that extra “oompf” during its operation, you should definitely consider the JP Reduced Power Spring Kit (hammer, Trigger, Diconnector). JP Enterprises is one of the most well-known names in the shooting world.

So when a product says JP on it, you know it’s going to be worth every penny because of the company’s commitment to producing high-quality parts and also because of how much they strive for customer satisfaction.

Though this piece is relatively small compared to the rest of the firearm, the trigger is certainly one of the most important parts. If your trigger has a “creep” or features a gritty feel, you may be unable to be as accurate as you’d like to be in gauging your rifle when you are about to fire. If you want a smoother trigger pull, a JP Reduced Power Spring Kit can truly do that for you. For competitive shooters or a law enforcement officers, you’ll understand the need to be able to accurately determine your shots.

A trigger spring upgrade can go a long way when trying to improve the function of your rifle’s trigger. This spring set will give your JP M15 trigger a 3.5- to four-pound pull weight. Instructions are included on how to accommodate Mil-Spec trigger and hammer components for a four- to five-pound pull weight. If you’d like to improve your trigger control, consider this JPS3.5T spring kit by JP Enterprises. Getting this JP Enterprises trigger spring kit is an upgrade you won’t regret.

This spring kit will yield a 3.5-4.0 lb. trigger pull with JP Fire Control parts. This kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components.

Application: Use of this spring kit allows for use of ammunition with low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions, but in the case of large-frame ARs and duty/defense rifles, domestic-manufactured ammo is strongly recommended to ensure 100% ignition reliability.
