I have a question on finishing the lower.
I was in the process of installed a Geissele ACT trigger on my lower. The trigger installs just fine, however the hammer is another story. I noticed that the hammer does not fall with enough force forward. In fact, initially it was stuck when the trigger was pulled. I manually pushed it forward about 10-15 times and it seemed to go forward in slow motion.
I suspected something wrong with the hammer pin holes so I took the hammer out to confirm and found them to be fine. But I did find
The semi-circle marks on both sides of the lower's front where the hammer was rubbing against the front of the lower. It seems like the lower has just a sliver of too much aluminum where the machined portion curves in the front. This is the area that is catching the hammer as it moves forward.
Since the camera phone was not taking good photos, I took the liberty of taking pics from Internet and drawing the offending areas in orange color to give you guys an idea of what area of the upper I am talking about.
My question is what would be the best way to remove this extra aluminum while keeping the finish somewhat smooth? I almost picked up a Dremel but thought I should post here before I start hacking away.:D
So what say you?
