    Great add to a stock trigger.

  • Too lite...

    Posted by Unknown on 1st Dec 2017

    Was too lite and would not even discharge a single round. The rounds would be dimpled, but we’re not struck hard enough to fire

  • Cheapest way to get a 3.5lb to 4.0lb trigger

    Posted by Bill on 30th May 2017

    I use these springs in ll my AR's. I can buy a complete lower, stick these springs in and have a VERY nice trigger. Why pay 100's of dollars for the same feel.

  • Exactly as described

    This spring kit combined with an ALG ACT will give you consistent 3.5lb pulls. I have only shot 270 rounds with this combination, but have had only one failure using PMC brass. From the appearance of the round it looked more like a bad primer than a light strike.

  • The best upgrade for your money!

    Posted by Cliffspot on 26th Jan 2017

    Tired of that sucky mil spec trigger? Get the JP Spring kit and improve your shooting! One of the first and best upgrades to your weapon is a trigger job. This drop in kit will bring a vast improvement to your stock setup. It even has polishing instructions to take that gritty feeling out! Before you sink a couple hundred dollars into an aftermarket trigger, try this and use the money you saved for ammo and more range time!

  • Best $10 you can spend on an AR

    Posted by Unknown on 6th Nov 2016

    I have used these springs on a few builds; MILSPEC, polished and nickel plated. Each install yielded a lighter, smoother pull. It'll take a 6.5 lb MILSPEC trigger down to about 4.5 lb. Start with the nickel plate, polished trigger, you'd think you spent a fortune.

    Words of warning, should not be used for real defense or duty rifles-- you may experience light strikes and failures to fire on harder primer ammo. Also on rimfire rifles this is not the best set up, you should opt for the enhanced reliability springs, or keep the MILSPEC hammer spring.

  • Reduces trigger pull

    Posted by Bob Hall on 18th Mar 2016

    I put this reduced spring in my Sig M400, as the stock trigger spring seemed a little stiff. The JP Enterprises Reduced Power Spring set really reduced the trigger pull and makes it easier to stay on target.

  • Reduces Trigger Pull as Stated

    Posted by Unknown on 21st Feb 2016

    I installed these springs, polished the trigger, and sear surfaces very carefully with jeweler's rouge on a dremel. These surfaces were extremely shiny after just a minute of polishing. Upon installation, I coated the surfaces with the Rydol grease mentioned in the instructions. The trigger pull was greatly reduced and the DPMS Oracle still functions as before. Very satisfied with this product. Wing Tactical was great with shipping costs and delivery.
