Jp enterprises reduced power trigger spring kit. - JP Enterprises Reduced Power Trigger Spring Kit For AR-15

Another great product from JP.Will give you a definite 3 1/2 lb trigger pull and even better if you do a little sear and hammer polishing.Works great with commercial ammo,occasional misfire with NATO ball ammo because of lighter hammer strikes and harder primers in military ammo.Definitely recommend this product,easy install.
