JP Adjustable vs. JARD 2 Stage Trigger Systems
Saturday, April 28th, 2007This is not so much a comparison of which trigger is best, but which application the trigger seems to work best in. At D9Firearms we’ve installed dozens of JP adjustable triggers in a variety of DPMS Rifles. DPMS is fully aware of their standard trigger, and is their first recommendation when discussing upgrades. Granted economics is definitely an issue when considering trigger upgrades. The second concern in upgrading the trigger is which trigger you should use?
Most of our experience has been with JP Adjustable triggers. They are not that difficult to install once you’ve done a couple and it helps to have the right tools (punch, grinder, small hammer, and loctite). The JP has smooth clean break which for standard AR-15 rifles is about 3lb. For the AR-10 (308 calibers) JP recommends keeping the original hammer spring to insure proper discharge, which has about a 4lb pull. However, I have used the lighter spring on my LR-308 bench gun, which of course is used to eviscerate menacing prairie dogs, and have never had a problem. (JP strongly recommends the heavier spring for Tactical and Law Enforcement AR-10 rifles.)
The picture below shows the standard DPMS trigger on the left and the JP Adjustable on the right. The picture below it shows the entire JP Adjustable trigger system. The JP uses the existing hammer, but the hammer shown in this picture is the optional speed hammer. The Speed hammer is a lighter which allows for faster re-engagement, which gives you faster target re-acquisition, when dealing with multiple threats.



Up until recently we have only installed the JP’s but decided to try a JARD 2 Stage NM trigger. We installed this in a DPMS AR-15 6.8mm AP 4 16” w/quad rail rifle. Knowing the JP feel, I immediately dry fired the rifle, and it was a completely different action. The break was crisp, clean, and immediate. Unlike the JP which seems to have a smoother trigger pull this just broke clean and crisp. This combined with the type of rifle we installed it on seemed to be a perfect match. The trigger mechanism does not seem so much geared for the long range accuracy as it does for driving multiple rounds crisply into an “able” style target.

The JARD 2 Stage NM is shown below and you can see the difference between the JP and JARD. As we stated it’s not which trigger system is best but which application is it suited best for. If you want to upgrade your trigger system please contact us here at D9. The typical costs are:

JP Adjustable w/o Speed Hammer $150 installed
JP Adjustable w/ Speed Hammer $185 installed
JARD (AR-15) 2 Stage $145 installed
JARD (AR-10) 2 Stage $155 installed
If you are interested in a JP or JARD trigger system please contact us here at D9. We would be glad to provide it loose or installed.
