I use the C7A2 at work everyday, so I wanted to make myself something different, and I've always wanted something like shown on the cover of the original Ghost Recon game
It started with a 10" Armalite A2 upper that I bought from my neighbor, and while I was on vacation I bought an Armalite M15A4 lower to pair up. Found an old carbine stock and installed a milspec buffer tube, picked up a cheap BSA carry handle scope until my Colt scope shows up in the mail, and acquired a fake XM177 moderator to replace the A2 flash hider. Since the picture was taken I picked up a loose black sling at work and got it on. I also ran it for a 3-gun match a couple weeks back, and it did great!
The next thing, small thing, to do is replace the flat bolt catch that Armalite uses now, with a "proper" bolt catch.
Anyway, I'm loving this little gun, and it's always fun to bring out to the range with my SP1.
