Obviously this thing is not going to be a pistol.  If anything, it is like a sub-machine gun.  I am leaning toward the 10.5" but wanted to solicit opinions.  I have the lower ready to assemble.  Just about to order the upper but wanted to see if anyone had good experiences one way or the other.

Thanks.

Bump.

I am in the process of building an AR14 Pistol with a 7.5" bbl.  My thinking is that you loose alot in the way of ballistics with both the 7.5" and 10.5" but I have full sized AR's for anything that requires accuracy.  I figure if I am going to build a fun ammo burner then it might as well be one that is more compact and in my opinion looks way cool, and the 7.5" fits the bill.

Just my .02
