My two carbines
The one on the left is a simple Surplus Ammo and Arms Carbine.
One on the right is a super lightweight build, which I didn't even plan that way. Weighs 6.75 lbs empty with Spike CHF optimum profile barrel, Rainier bolt and compensator and VTAC alpha rail. I might put a red dot sight on this one. Though about a magpul stock, but that would make it heavier.
Sorry for the bad phone photo, need to borrow my wife's camera sometime.
