Need some help building an AR: It's alive!!

^ Thanks guys.

I was searching around and found a few threads on AR15.com. Quite a few comments like this:

Makes sense. I just don't like it boinging again on trigger reset...maybe that was because my ear muffs were on the stock. I will find out tomorrow.
 
Greased the spring...much better now. Can definitely live with it.

Also the purple spring for the ALG trigger gives a significantly lighter trigger pull...Although I didnt have any better groups and I did have one light strike. I don't think it was the fault of the hammer spring though. It was the first round of a fresh mag, and bolt released with the charging handle...I think I didn't let it fully slingshot and the bolt wasn't fully locked.

The AR's Bolt Carrier free floating firing pin results in the rifles signature very light primer strike and should not worry you. This is an inherent trait that can not be altered.

I assume you are talking about the firing pin leaving a mark on the primer when a round is chambered? I mean that I pulled the trigger and it didn't go bang:

Sorry, I'm confused. The one on the left I pulled the trigger and no bang. I thought it might be because the bolt wasn't fully forward.

This is possible. The primer dimple on the left looks too small to be due to a light primer strike. To me it looks like the mark left by the firing pin when the bolt slams closed.

I have another brand new BCG here to compare it to, so I don't think there's anything wrong with it, but here it is:

So does the other brand new bcg function perfectly in that same gun?
Likewise does the suspect bcg cause light strike in another AR?
Process of elimination.

No I haven't tried the other BCG, but it appears to be the same as my current one. At this point I don't think I have a reason to suspect the BCG. I am chalking it up to user error for now (possibly easing the charge handle forward somewhat and not letting it go with full force). I'm going to be using the bolt release exclusively, and if it happens again I will reassess.

Let us know how it goes! Thanks.
 
Lube her up and sit in front of the TV and repeatedly cycle the action to break it in. After a few hundred times you will feel the difference.
