No holds barred lightweight build

[melensdad]

Of the nearly 100 ARs that I've been involved in building, this gun that I built for my daughter was by far the lightest. It uses a pencil thin barrel and a full polymer Cavalry Arms lower. The Cav Arms lower integrates the lower, handgrip and buttstock into one, very lightweight, monolithic unit that saves weight by eliminating many of the bolts and other parts needed to hold separate comonents together. Its also very strong and takes abuse (think Glock). While this gun is built in 5.56, it could easily be done in 6.5 Grendel (and obviously it would not be required to be pink!). You could shave another 1 or 2 ounces by utilizing a different gas block that doesn't include a front sight.
