1 pull 2 bangs or sell me your stock spring

[crghill]

I put my JP spring kit in last week and went to the range yesterday. I pulled the trigger and got a double tap. It happened three times in about 300 rounds. I'm looking for suggestions on what to do next.

I'd like to buy from someone a stock hammer spring. I've still got my stock trigger and disconnector springs but butchered my hammer spring by cutting one leg to short on the hammer spring. If you've got one you'll part with let me know.

I'd take that spring out, pronto. You have no idea of the mud storm you can get into with that happening even if it's unintentional.

 

[crghill]

Oh yes I do. I've read the stories. I've already disassembled the rifle and removed the springs. I'm gonna call JP today. By the way, something I forgot to mention is that I didn't polish any surfaces, all I did was install the springs.

quick question did you chnge all the springs out and if you did.. pull the trigger spring back out and bend the legs down more so they will apply alittle more pressure and reinstall this should fix the problem.. sometimes the springs get bent slightly in shipping and if they do it sets the trigger weight to light for the disconect to work.. but just bend the legs away from the squard off end and reinstall while your there you might wanna stretch the disconect spring alittle too.

I did change them all. I'll try bending them a little and see how that goes. Thanks Belt Fed. You don't happen to have a stock hammer spring laying around do you? If so, want to part with it?

Huh. I've installed a couple dozen JP spring kits in lots of different ARs, both with and without using JP hammers and triggers, and never had a doubling problem. I'd adjust the trigger spring as Belt Fed suggests, maybe tweak a bit of extra oomph on the JP hammer spring, too, but I'd check the disconnector spring, as well. You may need a heavier disconnector spring. The full JP kit (hammer, trigger, and all springs) comes with a heavier disconnector spring, which is needed to avoid doubling and give the disconnector reasonable life expectancy with light trigger pulls. (Accuracy Speaks kits and some other brands have notoriously short disconnector life spans, but can be improved with a heavier disconnector spring, too.)

As I've mentioned in other threads, if you are going to keep your stock hammer and trigger and use light springs, it is a good idea to cut the "hook" off the hammer and lighten it, which both shortens lock time and reduces bounce and wear on the whole fire control group.

As for a stock hammer spring, I expect I have one in a parts box somewhere. Send me a PM if you still think you need one.

 

[crghill]

So, what about using the JP trigger and hammer spring and the stock disconnector? Would that work?

 

[BELT_FED]

probably not.... just bend your trigger spring to where the legs and square end are at an angle away from each other.. then stretch your disconect spring alittle and reinstall this should fix the problem... removing weight from the hammer does help with wear but your problem can be fixed by just bending the springs

These rifles weren't meant to be competition accurate. So why make such a fuss about a slight hard trigger pull? I like mine the way it is.

I'm pretty sure I've preached that since day 1.. that they r not target rifles.. but I use my 15-22 as a trainer for my ar... my ar has a 3 lb tripper in it I m&p had closer to a 9 lb trigger.. so I fixed it... by the way my target rifle has a 10oz trigger pull... I really don't consider 3lbs a comp. Trigger anyway... but this is only .02 and what would I know
