Thoughts or opinions on these inexpensive uppers?
Bragging or bitching? Whatever your point may be, I have already indicated numerous times what I think, and have heard here on this thread and from another guy on the 'Fire, eg they seem to work.
For chits and giggles I'll add, a 7.5" 5.56 is not for me. It was $218 pre-panic IIRC.
