JP Springs-Yellow, Red & Gray

[Burk Cornelius]

What springs or combination of springs do you use and why?

From JP's website:

• 3-3.5 pound trigger pull for competition/recreational use. Kit includes yellow color coded trigger and hammer spring.
• 3.5-4.0 pound trigger pull for enhanced reliability and provides good ignition reliability with any ammo. The red hammer spring with yellow trigger spring is also the minimum required for a 308 AR-10 set up.
• 4-4.5 pound for police duty, military or any application in which 100% ignition reliability is demanded with low sensitivity primers or a heavier release is demanded by LE department requirements. May also be used for 308 AR-10 set ups. Kit includes grey hammer spring with yellow trigger spring.

Yellow for mine because I tried it with a chopped hammer and polished trigger/hammer and liked the results. It's been a Hell of a lot more reliable than my adjustable gas block for sure

Have you (or anyone) ran both yellow springs with a full hammer?

Cut the tail off your hammer. Run the yellow springs

I did for a long time with no issues. With some harder primers you might get the odd light strike.

Whack the spur off the back of the hammer with a dremel and its good to go.

I am currently. Not a lot of rounds since installing them, but no issues yet. Using CCI #41 primers.

Q2: Is the red spring similar to a stock spring or is it somewhere in between yellow and stock?

I ran the yellow springs with a stock hammer, and had real bad problems with light primer strikes!! Then I cut the spur off the back of the hammer, and it runs really good now and the trigger pull is light and it shoots real good! Matt felt it and said he loved it.

Lighter than factory.

I've got the 3.5-4lb. yellow/red JP springs in my 14.5" AR and love it. I actually just installed another set in a lower that I put together. Both lowers have Spike's Nib battle triggers, but oddly the new lower seems to have a much lighter trigger pull than my other AR, even with the same setup. Not sure why... But I think haveing only spent $70 ($59.95 for the Spike's battle trigger + $9.99 for the JP enhanced spring kit) on this setup it was well worth it. It "feels" more expensive than that! :nyam:
