On a whim, I used hot water to negate the glue, and checked the job I did with a drill on its AR. This is what I found
The drill has destroyed the place where the plunger is supposed to sit. The black the inside of it is where the O-ring sat,instead of the plastic.
If you have used a drill, check out the internal, to see if it is too broken to salvage.
I am going to salvage all the parts i can, and dump the rest. It was a first attempt, and i have another NF to put the C368 spring in, so not all is lost <:)
