I installed a RRA 2 stage NM trigger in my AR-10 this week.
I took it out and experienced a number of light strikes on primers. The firing dip would dimple the primer, but not hard enough to ignite it. A second try would fire the ammo.
I was getting one of this failures every 5-6 rounds using Portugese surplus ammo. I didn't have any other with me to try.
My AR-10 is still relatively new with about 150 rounds or so through it. It was clean and well lubed.
I contacted a RRA technician this morning who told me the only thing to do was to use different ammo. That's fine except I have 4 cases of this Portugese stuff and no other .308's to use it in.
When installing this trigger, I noticed the hammer has less mass than the original hammer.
Does anyone make a stronger hammer spring? I'm tempted to swap the hammer spring out for the original hammer spring and see if that makes a difference since I didn't have any trouble with the original trigger/hammer combo.
Maybe I just need to shoot it more until it breaks in?
Any ideas?
Thanks,
Ken
