are you sure the hammer spring legs are sitting on top of the disconnector pin and not underneath,if the spring doesn't apply enough pressure on the hammer you will get reduced hits on the primer

Something else that I just thought of if you push the pin in the hammer can you freely turn it or is it so tight that it will not let the hammer rotate easily,If it doesn't rotate freely it can cause light primer hits and being a new gun may be tight

Did you lube the parts prior to assembly? Is the gas tube lined up correctly with the gas post in the front sight base? Is the gas key tight and properly staked? What buffer are you using?

Unless I miss my mark, he's using a carbine-length buffer with a mid-length upper. I would normally suggest to buy an H buffer ($20) and extractor upgrades (a few bucks), which would be appropriate for a mid-length system with a carbine buffer/stock assembly, but it sounds like the rounds simply weren't firing.

I have anti-rotation pins (KNS Gen II)

Everything was lubed, probably a little over lubed. Gas tube is definitely lined up correctly. I checked with low pressure air with barrel chamber pugged. Good air flow. Gas key looks properly staked and is tight. Using whatever buffer came with the BCM M4 6 position buttstock kit.


Correct. Carbine length. Supposed to be ok with this buffer right? Already upgraded the extractor with the D-fender o-ring. May upgrade with H buffer soon.

Uhm. . . . one more thing. I am absolutely embarrassed to post this.

After the FOURTH inspection of my hammer and trigger spring installation, I found the hammer spring was installed INCORRECTLY!!

Somehow, even while looking at the instructions, I installed the hammer spring in the wrong direction. Now, the hammer really smacks the crap outta the firing pin! I bet this is the problem but I wont know for a couple days. I wont have a chance to shoot until late this weekend or even early next week

This upgrade comes recommended.

Glad to hear you finally ID'd what might be your problem. The lack of firing was throwing me, so the hammer issue makes sense. Get us a range report and see how she fares now.

Don't be to hard on yourself,sometimes on a first build it's easy to make some little mistakes,but I bet you never install another hammer spring backwards.After all the suggestions of what to check I was about ready to say you got some ammo with crappy primers lol

make sure your bolt is seating and check/change your magazine...if you can try a different one to see if that helps..they may not be feeding correctly.
