This is a lightweight AR that I built for somebody with shoulder problems, who was looking for a reliable gun that wouldn't fatigue them as much as a standard AR configuration would at classes. The foundation is a Robar polymer receiver set, as found on that company's Polymar-15 guns, and a LOT of the parts are titanium. The end result is a gun that weighs in at 5lb 15.5oz, with the weight biased toward the center and rear. Light enough to be light, with good components to ensure it wasn't fragile.

No cheeseball parts were used, breakdown as follows:

LOWER:
Robar receiver
Sionics LPK
V7 Weapon Systems mag catch, bolt catch, ambi selector, castle nut and receiver endplate, takedown pins
Magpul MOE-K grip
BCM Mod0 stock
BCM receiver extension, carbine action spring, H buffer

UPPER:
Robar receiver
Faxon 14.5" Gunner 5.56 barrel, mid-length gas
Pinned Battlecomp 1.5 titanium
Faxon mid-length gas tube
SLR Rifleworks Sentry 6 Set Screw Adjustable Gas Block - Titanium
V7 titanium bolt carrier
BCM bolt
Midwest Industries SSM M-Lok Series 12" free-float forend
Magpul MBUS Pro (front and rear)

The ejection port cover that matches the upper receiver is not installed, but will be included so that the purchaser can install if desired. 200 rounds were utilized for adjusting the gas block to gas the system right, zero, and general function-check. Otherwise unused.

$1500, price is FIRM.
