NEA Soft Strike

[Sniffer]

If you didn't say anything about the spring I would have asked if that light strike primer is deeper in the pocket than the other...

Yeah that picture sure makes it look that way, that was something I was conscious of but I had this happen a bunch of times and for sure some of the cartridges were totally flush

Isn't this one of the reasons for 300 blk.
The 7.62x39mm ar mags work sometimes
The ar15 firing pin works sometimes with 7.62x39mm
7.62x39mm ammo works sometimes in ar15.

Just saying it's a common problem and a lot of sometimes for the ar15.

Is this based on some factual info? What you just wrote makes no sense

Those have been my experiences so far but I wouldn't read too much into that, I expected the gun to be tight being brand new and once its been used a little I expect a good portion of those issues to disappear (certainly the magazine and feed/extract issues)

The FTF was, I believe, as a result of one of the trigger pins being dislodged on one side and reducing the hammer force resulting in a light strike. My next trip to the range will hopefully be smoother.

The fact that the pin can easily move from side to side and cause this issue is a concern to me but at least I`m conscious of it now. I will update NEA to see if this is normal and what my options for a solution are.

My guess is that statement was based on my recent experiences in this thread.

I am optimistic that most if not all of the problems will disappear now I`ve found the trigger pin that was dislodged and get a few rounds through the gun to free things up

If its an nea bolt carrier group, it should have the extended firing pin

rubish!

Can you elaborate?

I put all the measurements in a previous post

Crazy thing is that the pin is only held there with the force of the internal hammer spring, and clearly is free to move from side to side resulting in the issue I had. Is there any way to counteract this? Blue thread locker on the pin?

Don't put blue thread locker on any pin.
The hammer spring legs should be sitting on top of the trigger pin. The trigger pin has a groove that the hammer spring legs catch which prevents the pin from walking out which it sounds like yours did. The hammer spring is easy to install backwards and if so, it can result in light strikes as well as less pressure on the trigger pin allowing it to walk.

Thanks Runningfool - that makes a lot of sense

I'm interested in knowing if this was the solution as I'm having the exact as issue, I got my rifle on the EE a while ago (I know buyer beware), I've tried multiple ammo types from surplus to AE, tried a wolf hammer spring, XCR mags and I'm running out of idea's. Can't find anywhere that sell enhanced firing pin's, I've heard some people have shaved a few thousand of an inch off the top of the base of the firing pin so it hits the primer a little deeper. But that method seems a little too extreme and risky to me. I'm going to go double check the spring install with the photo's Runningfool provided (thanks by the way)

 

[sky52]

Hard to explain here. But google extended firing pin online. They are ever so slightly longer to make a deeper indent for the lack of a better term onto the primer

 

[TheWhole9Yards]

my money is still on hammer spring, although anything is possible

*Update*

Went to the range today, put around 80 rounds down the range and without doubt the issue is the pin that I suspected

Happened again today - probably 4 or 5 times

The pin simply slides out until it is only supported on one side resulting in the mechanism binding and reduced striking power

When I got home I stripped it, there is two grooves in the pin (one in the middle and one at 1/4 from one end) but I cannot see anything that might hold it in place except what might be a spring (really hard to see) in the the middle of the hammer (which would align with the centre groove)

Ive attached some pictures

As it sits Ive tried the pin in both ways and it made no difference, I am able to push the pin in/out in either direction - something is not right here

Thats the hammer pin backing out not the trigger pin. Does the hammer pin click when its halfway inside the hammer pivot hole if you push it through without installing it in the rifle? If not the J spring staked inside the hammer might be broken or weak, and you might need a new hammer.

Umm yeah, I said the hammer in my last post

No, there is no "click" (i.e. the type you would expect when the spring snaps into the groove) when I put the pin in

Yes, but everyone pointing out a broken or inverted hammer spring which would matter for the trigger pin but has no bearing on the hammer pin.

Then I expect that this is the problem. There is a small spring staked inside the hammer called a J spring. If it broke there is no way to change it, you will need a new hammer.

Ive updated NEA so lets see what they come up with.....

That's what I as thinking as well. On my spare FCG I have to knock the pin out of the hammer with a punch and mallet. The pin is basically captive inside the hammer.
