Re: MagPul MS2 sling
I'm a Magpul fanboy, I love my MS2, but I recognize that it has distinct limitations. For my 7.5" SBR AR, it works very well. The MS2 lends itself well to SBRs being used for tactical shooting, training and competition. If you're running a short carbine, or a subgun, the MS2 will work well.
Once you get out past 14.5" barrels, the rifle gets too long and the single point configuration becomes very unwieldy and awkward. The rifle flops around a lot. The sling is also for support, but not for carrying the weapon. It doesn't transfer weight well, and it can start to dig into you. This is especially a problem with heavier rifles.
It's a great single-point sling, and the best I've ever used. It's hard to find single-point slings that don't use bungee material and allow the rifle to bounce around.
In terms of a 2-point sling, it leaves a lot to be desired and I would steer towards other options. There are many much better options available for two-point slings.
I think the MS2 excels in a specific niche. It works very well when you're doing the kind of shooting that you would in a Magpul Dynamics course. If you do something different, then you would be better served to go to a different sling that better fits your application.
I know Magpul is already developing the MS3 sling to redesign the sling to a better configuration, but I don't know what all is being done.
As it stands, a VTAC or Vickers sling will be a better investment for overall general AR use.
