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.

  • Cheap upgrade

    I saw no change in my trigger pull after adding these springs. However my rifle has a Strike Industries enhanced lower parts kit with a 4-4.5lb trigger already. These springs may improve pull with a factory mil-spec super cheap-o trigger.

  • Very impressive for around $10

    I have built about 5 ARs now... and this one has made the trigger extremely light and crisp. I'm thoroughly impressed, and I will probably be using this as an option for anytime I'm building another AR with a tight budget. You will not be upset if you pick this up!

    First time buyer from Wing Tactical. Just purchased three sets of JP Enterprises Enhanced Reliability Trigger Spring Kits (JPS3.5T). Arrived in just three days. Installed the first set in my tactical AR. added the recommended Lydol Grease and promptly got a most respectable 3.0 lb. trigger pull. This was on my DPMS 16 in. AR. Safety tested as recommended and was good to go. Thank you . 5 Thumbs up.

  • Crisp Trigger!

    I did a inexpensive trigger job in my Colt LE6920 and I replaced the trigger spring "only" with this kit. So far is shooting great without any issues.
