If I could only have one weapon I would have the carbine.
That is an adjustable 2 point tactical sling. The carbine can be carried on my back or in front. It will be at the ready.
I would post some pics, but the new version of windows isn't letting me.
Two choices for rifle that I own. Different reasons for having both of them.
I have a FN SCAR in 5.56 its a nail driver, so reliable its unbelievable. Accurate as all get out. I like it because its tough, and works a little better for us left handed shooters.
I also have a LWRC M6A2 thats got some left hand converts, thats pretty killer. Its a lot more reliable than a gas piston AR, and its accurate. I would have it in my jeep as a backup because its a AR and parts are going to be available for it. Parts for the SCAR are going to be harder to come by.
