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 Enhanced Reliability Trigger Spring Kit. JP Enterprises is an extremely well-known name in the shooting world, partly because of the company’s commitment to producing high-quality parts and also because of how much they strive for customer satisfaction. So when a product says JP on it, you know it’s going to be worth every penny.

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 enhanced reliability trigger 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.

    I haven’t been able to get to the range yet but the springs went in with no problems and the pull wait is definitely noticeable, I am satisfied with this product.

    this is a good upgrade for stock triggers and you cant afford a drop in trigger pull went from 7 or 8 pound pull to a 4 or 5 pound trigger pull. well worth the money
