Questions & Answers
Does it have to be 223?

These springs are for recreational or competition shooting only and should not be installed in any rifle used for defense or duty applications or any AR-10 type rifle. The can be used with other calibers from the AR-15 platform, but reliability will be reduced with hard, low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions.

For full auto, duty, or large frame AR's, the JP Enterprises Enhanced Ignition Reliability Trigger Spring Kit would be the recommended springs to use.

EASY Fix to a heavy trigger. by Longfastglass, Verified Owner, November 6, 2024
Don't have the Fun Tickets to drop on a new trigger? These springs are the fix! I don't use the hammer spring as the strike becomes toooooo light to reliably ignite your primer. Just swapping out the trigger shoe spring is enough to drop your 5+ L...

Great bang for the buck by Tyler, Verified Owner, April 18, 2024

Product Info for JP Enterprises Reduced Power Trigger Spring Kit For AR-15

Replacing a complete fire control group can be quite expensive, with the help of the JP Enterprises Reduced Power Trigger Spring Kit for AR15 your stock AR-15 will have a 4 to 4-1/2 lb trigger pull; with JP trigger parts the same springs will produce a 3 to 3-1/2 lb trigger pull. If replacing the entire fire control group isn't in your budget, or you just have too many AR-15s to justify a complete trigger kit in each of them, the JP Enterprises Trigger Spring Kit will significantly improve your stock trigger without breaking the bank. This kit includes a trigger, hammer and disconnector spring. For an amazing way to be sure you have reliable and long lasting enhancements on your AR15, choose the JP Enterprises Reduced Power AR15 Trigger Spring Kit.image
