Lead Star Arms has introduced a lightweight AR-15 stock called Ravage. It is CNC machined out of a solid block of 7075 T6 aluminum and weighs only 6 oz! It is a fixed stock, that is to say, a non-adjustable one. The way it attaches to the buffer tube (or receiver extension, if you will) is that it clamps on it. So you need to slide the Ravage stock onto the buffer tube and tighten the screw to fix it in place.
When attached to a carbine length buffer tube, it makes the overall length of the stock (from lower receiver to the butt pad) 9.5″. The stock also features a slot for sling attachment. Perhaps it would be better if there was a QD socket, too. It is also Type III Class 2 hard coat anodized and comes in different color options: red, blue and black. The last color looks more like gray to me, but maybe it is just me. The Ravage stock is available on Lead Star Arms’ website at an MSRP of $89.99.
I am a huge fan of reducing weight wherever it is possible without altering the action and compromising the strength and rigidity of the firearm. The Ravage stock does just that! However, it also has a feature that I am not a fan of at all, which is the metal parts contacting your face. Now, if you are less likely to find yourself in an extremely hot and/or cold environment, then maybe that is not something to be concerned about.
