I just received my 16" rifle kit from Del-Ton last week. I only added the green furniture and the chrome lining and it made it to me for $498 w/shipping. I ordered a Doublestar lower from Aim for $108 w/shipping. Then add $25 transfer fee and I have a complete flat top for $631. I already had a detachable rear sight laying around so I used it and tried the thing out yesterday for the first time.
It functions perfect, it looks damn good and I built it myself (first timer here). You can't go wrong with Del-Ton. You can get the basic kit and upgrade later when funds permit and you see what mods/upgrades are wanted/needed. I had so much fun putting my own together that I am getting ready to buy another lower and do it again.
I already had a Bushmaster that I bought new so I knew the basic function before the build. wheb I opened the lower parts kit and saw all the parts i kinda got scared. But due to the fine folks here and all the "sticky" links provided, I was able to open all the bags of parts and assemble my rifle in less than hour.
Now is the time to buy before it is too late.
Changes in the Gov. are on the horizon.
Have NO fear, if you build your own, there is plenty of help afoot here on this fine board.
