Pull the trigger and the 1st round goes off
2nd round gets loaded
Pull the trigger again, but it's not set
Pull the Charging handle
2nd round ejects and 3rd round goes into chamber
Pull trigger and bang like normal
afterward, inspection of 2nd round revealed a small dimple on the primer
Repeated about 10 times with the same result
Hey Drew! So the issue is just that the hammer isn't being set and is following the bolt back to the forward position. So it can either be the ammo doesn't have enough pop to push the bolt al the way back, the spring is to heavy and isn't letting the bolt come all the way back, or the locking mechanism on the hammer is jacked so it won't hold it.
With that I would say it is the ammo or spring, if you can rack it back and it locks the hammer then the locking mechanism should be fine.
So you're saying that it is going far enough back to load a new shell which means it is definitely passing the point where it "locks" the hammer if you pull it with your hand? If that's the case then it has to be the locking mechanism not working when at full speed vs just racking it?
Heck yea man, I recommend every AR owner gets an after market trigger, makes a whole lot of difference. Have you shot it with the Timney?
Nice picture...

. Yeah, I like the two stages myself
