Luth-AR M4 Buttstock Mil-Spec Kit with Rear Sling Swivel

Luth-AR's M4 buttstock in the mil-spec kit version. The stock is the familiar M4 carbine shape with waffle sides, and this configuration adds a rear sling swivel mount at the toe rather than leaving you with only the side slot.

A rear mounted sling point pulls a rifle differently than a side mounted one. It keeps a two point sling flatter against the body and stops the buttstock rolling outward when the gun hangs muzzle down. This is the mil-spec .223 kit version, so the stock comes with the hardware behind it: a six position carbine receiver extension, the buffer, the spring, a latch plate and a lock ring. That covers a lower build from bare receiver to shouldered rifle without a second order.
