After picking up an M18 last year and really liking it, I decided to build my own version of it. I really like putting things together so the fact that I could build thing completely, kind of appealed to me. Started with a stripped FCU, added a parts kit (damnit those are expensive!), then upper parts and went with a Wilson Combat grip module. I also put in a Apex forward set trigger bar and the Armory Craft tungsten weight rods. Hopefully see how it shoots tomorrow.
