JP Enterprises Fire Control System Trigger Spring Kit AR-15 4-1/2 lb

I can't believe I haven't done this before now. This drastically improved the trigger pull on 2 ar rifles. 1 300 blackout and 1 450 bushmaster. Both were averaging over 6.5 lbs on my trigger scale and now average 3.5lbs. Feels crisp and no more creep. I polished both and added high quality sear lube but was getting these results before adding the grease. Ordering more for future builds

I know some reviews say that the spring difference isn’t noticeable but I have this paired with a cheap BCM trigger that went on sale I picked up for like 43 bucks and it’s waaaaay smoother than my stock trigger.

while i was installing these springs i went ahead and filed on the hammer-disconnector interface and polished the sides and interface of trigger & hammer to reduce friction. applied a dab of synthetic grease to contact points & the action feels much more responsive, lighter & predictable. it is said that the best triggers have a pull which is so light that the break is unpredictable but compared to the heavy. gritty, sloppy originally manufactured action as it comes from the factory, the finished product of these springs, some filing & polishing the result is nothing short of drastic improvement.

Purchased to lighten the standard trigger springs (which measured nearly 7# on my PSA AR - EPT) - after installing I found little change from stock and when measured, came in at 6.6# which is unacceptable when the ad touts significantly less. Called manufacturer during working hours and the phones were not answered; contacted PA and they said would follow up

Anytime I am using a mil spec trigger, I always upgrade to these springs. 100 percent reliable and the trigger always feels crisp. Highly recommend for a mil spec trigger.

I have used theses springs in at least 6 AR builds including 7.62 and 6.5
Grendel configurations. I always achieve 5 - 6 pound consistent, reliable. and repeatable trigger pulls. I prefer to not go lower than 5 pounds for safety reasons, although US Army thought 10 pounds was optimal. These springs are by far the least expensive, user friendly trigger upgrade available and I highly recommend you try them outl

Same as standard
