Does anyone have any experiance building an AR10 from a kit? I was wondering if it was as cost  efficient as building your own ar15. Also. are the fire control parts for the lower the same as for AR15's? Thanks...

I don't think you save much money but I did build my own Eagle Arms AR-10 stripped receiver.  I did it as I wanted an AR-10 and I was originally planning to build a 260 Rem NRA Highpower match rifle.

Most of the parts in the AR-10 are the same as the AR-15 but I would just buy a stripped Eagle Arms lower and a AR-10 lower parts kit as there are a few parts that are not the same.  The AR-10 assembles the same as an AR-15 so it is no big deal!

As for the upper, I would just buy a complete upper unless you are bent on doing it yourself.  I have never assembled an AR-10 upper but it is the same as an AR-15 except you will need a new barrel wrench.

Personally, after having the Eagle Arms Lower in my safe for some time I ended up buying a normal 308 upper and I never did build the custom paper punch.  Now, I keep getting older and my vision is loosing it's edge so I don't really need a full course rifle anymore so I can shoot tiny groups at 600-yrds.  Hell, I am lucky if I can find a local 200-yrd rangs where I live now...

I've got some AR10 parts for sale, cheap!
