Ok, so I decided on the upper and have purchased an LMT full upper.
spikes lower, rock river trigger , all magpul moe stock , grip , and rear sight.
And all the parts for the lower. Got a set of roll pin punches as well. I am borrowing a castle nut wrench. Any tips and tricks?
I purchased everything from 5280. Great selection , fantastic personal service and the prices were great. Of course the Internet is cheaper, but I keep it local when I can. Thanx to you all who helped me with info.
