Although the description says it's tan, it is more of a greenish brown color. I picked this over the black or OD because black is just too...not different...and the OD might not work as well as this. If you are in the woods around a bunch of dead plants and stuff, the OD will stand out. The tan-like brown color works well in shadows, against foliage, and at night. The bungee aspect ensures you have some snag room for if you get snagged on a bush and it lessens the stress on your shoulder. The two adaptors are nice and should both work on any given M4; i haven't checked it on any other guns yet.
two adaptors that both work well
buckle for quick detatchment of sling if needed
the bungee aspect of it lessens stress and gives you some slack for if it gets snagged on a branch
better than the reel steel sling I have here at home ^.^
not really sure if there are any...haven't used it a whole lot yet
