The disconnector is held in the receiver by a pin through it. It will move with or without the disconnector spring assuming the hammer is in the vertical position.
Take out the trigger assembly and check it. It's just two pins.

Mark and Lew, I went ahead and removed both trigger and hammer assembly and I found that the disconnector spring was indedd upside down so I put the fat end of the spring down and looked everything else over. Mark, the spring is not yellow, could you share what that would mean, if so? thanks again guys :dance3: ill give it another test in the same weather, just colder.
If the disco spring was upside down, you found your problem. JP sells yellow and red reduced power springs which are know for light primer strikes. I would test again when you can and bet you will be fine.
Thanks all, esp TacMark. This effort will give the repair and Froglube a run, its now 12F:cool:
TacMark and Lew... winnah, winnah, chicken dinna... combo of upside down disconector spring and after I dug up some illustrations of how a hammer spring should appear installed, and it wasn't correct, I went in, made the corrections and took the .300 out in 13F and unloaded a mag without a hiccup. Thanks guys.
Keep your weapons as far away as possible from "THAT" armorer. He botched two simple procedures that are correctly shown in numerous videos and manuals. The guy actually gets paid to be that incompetent? So sad.
An improperly installed hammer spring is the most common cause of a light primer hit on a new build. http://img.photobucket.com/albums/v5...5forme/FCG.jpg
This thread should be a learning tool. The next time someone says I don't need to learn how to work on my AR, or any competent "gunsmith" can do basic work on an AR I want to direct them here.
I've learned through experience of 25 plus years around guns (new to the AR platform)the difference between armorers and gunsmiths, no offense, to either specialty vs. career. In this case, I was giving a new armorer (volunteer) a chance to build up a lower for me for his experience and self confidence. I'd never take a weapon from armorer or gunsmith and deem it worthy without a test drive. In my case, I actually learned a couple of lessons from this build from a human riding a learning curve... and with the help of my M4 friends, the case of trouble shooting a new build. I will have a low key talk with said armorer, pointing out the errors, especially Eric's illustrated epic and most frequented cause of light primer strikes on the new AR build. Be safe.
