I bought some ammo cans and a single point sling from them at a gun show. The gal that runs the place is about as round as she is tall....so you have that in common.

Btw..set yours up to take a single point sling, usually an dealio that goes between the lower and buffer tube. Also, go to Brownells.com, the have and ar15 dream build app....cool and you see how crazy the prices can go. If you get a picatinny forearm, get the rubbr covers, damn things will tear you up.
