paid 400 for the complete upper and 125 for the stripped lower. the billet lower is very nicely machined. the internals are rock river signal stage trigger i think it was around 75. 300 for the eotech, and 65 for the flip up rear sight. have less than 1200 in it once you figure grips, clips, single point sling. it all depends on want you want. ruger started making them and from the factory you get everything including piston driving recoil system, chrome barrel and bolt, flat top. all for between 1500 and 1600. for that kind of money you can also look at rock river, stag, smith and wesson, bushmaster, remington, and you might even find a colt. some of these will be cheaper than that ruger that's fully loaded. but its like anything else more options more money. Alex bought a cmmg, which in built here in missouri, they make a good gun and it is priced very reasonable. if you make sure not to use corrosive ammo you won't necessarily need a chrome lined barrel. there is allot of options, it all depends on want your wanting. a sniper rifle .308 or a m4 close quarters weapon. one thing about building you own is you can do it in stages, you are not spend a big wad of money all at one time. as far as putting it together, there is nothing to it very simple design.
