The goal here was not to build the lightest possible AR, but the lightest practical and reliable AR. I ruled out anything but a steel slide lock/LRHO, flimsy minimal stocks, conventional polymer or magnesium lowers with a weak spot at the buffer tube mount, and aluminum bolt carriers.
It has been shot a few hundred rounds and seems accurate (lots of touching holes at 50yd). With the adjustable gas and low reciprocating mass, recoil feels no more than a standard AR and with less movement of point of aim.
I am very happy with the results. I was going for 4 1/4lb and almost made it.
Weight: 4.32lb (4lb 5oz)
As pictured (with optic, QD optic mount, 3-pt sling, QD sling hardware, QD Keymod mount, Houge grip): 5.22 lb (5lb 3.5oz)
