Uppers, lower, stock all plastic. Carry handle, flat top rail, barrel, flash hider, tele stock tube, front sight assembly, trigger, selector, mag catch, bolt catch, charging handle, ejection port cover all metal.
Has A2 sights, fully adjustable, kind of pointless on a weapon effective to 150 feet but neat none the less. 4-position stock detachable carry handle all work.
Cost, gun itself sans battery and charger can be had for $275 here in the states, or $225 if bought over seas. I got a package for 4 bills. It included rifle, battery, charger, discharger, high cap mag, bag of 3750 bb's, and included shipping.
