New Spike's Battle Trigger w/ JP springs - Fail

[jdub229r]

Guys - I just installed a Spike's nickle boron battle trigger & 3.5 lbs yellow JP springs in my BM ORC 308. It's a huge improvemnet over stock (8 lbs). I read before that the yellow springs might cause light primer strike issues with steel case. Anyway, I was in fact getting light primer strikes - Hornady steel match (Wolf cases) went off 4 out of 5 times & Monarch steel case (Barnaul) were 2 for 5.

My question is; can I leave the lighter weight yellow trigger spring & just change the hammer spring to the Spikes. Will that make a diffence or is it recommended? Should I just put the springs in that came with the Spikes? I wasn't expecting the Spike's to be a match trigger; only that it would be smoother than stock - which is what it is.

off the jp 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.

■ 4.5 pound for CMP service rifle competition. Kit includes grey hammer spring with grey trigger spring

judging by what ken said, i would defininately run the red hammer spring, if not the grey. give it a try and let us know

Looks like JP's site indicates that using the other springs on a normal trigger won't help much. I'll leave the yellow trigger spring in; I've got 3 different hammer springs in my parts bin that I can try to see if they give me a decent pull & still work. I'll post the results after my next range trip. Thanks in advance!

As a general rule I run the Yellow Trigger and Red Hammer for all of my setups. I find that it works excellently well.

My Spikes NB fire control system works fine with the springs came with it , on a 308 rifle.

It has dropped trigger pull weight each time I shoot it . Its at 5 3/4 # pull from 6 1/4# when first installed .
