Proper Install of AR15 Trigger

So I recently picked up a Spikes Tactical battle Trigger for my AR15. Some of the features of this bad boy are:
- Nickel Boron finish for a smoother trigger pull and enhanced reliability
- Breaks at about 5-6lbs in most applications
- Works with all calibers
Well after I had installed the trigger, I did what any red blooded male would do, I fucked a donkey. No, ok, no, just kidding, I went to the range of course and that is where I ran into some trouble. I went through a whole box of PMC Eagle 223 flawlessly. Next I loaded up 20 rounds of Federal XM193f, you know, the brown box special or often times it comes in a white box. Well, I had about 6 failure to fire rounds. It appeared to be a light primer strike, which is strange considering I just put this new battle trigger in my AR15 right? I also have a titanium firing pin for that extra punch when the hammer hits the back.
So upon further investigation back at the ranch, I realized, I installed the damn trigger spring incorrectly. So, what did I do to fix it? I reversed the spring. Below is a video I made that will demonstrate the proper way a trigger should be installed in an AR15. Hopefully it helps someone out there.







Well its good to know that there is someone willing to share what they know in installing AR15 trigger and I’m pretty much excited to give it a try.Furthermore it is really important for an individual to know how to install this stuff in order not to keep on relying someone else.
