I built this from all new parts. I am happy with it and I can't wait to shoot it. I had lots of issues choosing the parts I went with. I still would like to upgrade the trigger later. But the RRA 2 stage is fine.......
I took it out today and fired it with 55gr Wolf ammo today. Worked like a champ!
I used the following:
Armalite M15 upper/ lower
Wilson Combat barrel fluted 16 inch
RRA National Match 2 stage trigger
A.R.M.S. 41-B Silhouette Folding A frame front sight
A.R.M.S. 50 M-CV rail system
A.R.M.S #40L rear flip up
Standard charging handle
POF flash hider
Dan Young National Match bolt Chrome
Magpul Mags/ Grip/ trigger guard/ CTR stock and pipe
Standard buffer and spring
Standard Gas tube
Finish is Duracoat Snow gray, dusted with black and satin clear coat.
