So I'm convinced that I need a sling for my Smith & Wesson M&P 15-22. It will primarily be used for plinking/range time and such, and I'm looking at two-point slings. The gun is super light (~5lb), so I'm not too concerned about something with padding, but a wide strap and/or bungee would be nice (not essential). I've been doing some research here and on other forums/web-sites, and I've narrowed it down to what seem to be the three standout slings that everyone recommends: Vickers Combat Application Sling (VCAS) - $50.00 Viking Tactical (VTAC) - $35 (original) / $40 (wide, padded) Irene Adaptive Sling (IAS) - $35 Is it really just apples to apples between them? Honestly, I don't see much of a difference between the VCAS and the VTAC. The IAS though is more unique... I really like the IAS because it's able to quickly convert from one-point to two-point. But it can't actually be shot in the two-point position because the webbing is too short. (In two-point mode, it does seem a lot more secure to your body though) So you ONLY use two-point for transporting the weapon and all the shooting is done in one-point mode. Should I care though? Which do you guys prefer shooting with, a one-point or two-point sling? Then as far as attachment, since the M&P 15-22 isn't a normal AR, the receiver and buffer tube is actually one piece, so I can't install a sling plate there. (I didn't get the MOE version which comes with one installed) The IAS comes with a nylon buffer tube sling mount that will work, but they recommend a rigid mount instead... That pretty much makes my argument for the IAS and its one-point capability a moot point, huh? So I'd really just use a rear stock mount and a front rail sling attachment unless I got creative with a clamp-on single-point mount or something... As far as sling mounts, I figured I'd just get a Magpul RSA for the front, but should I consider some type of swivel instead? There's a ton of stuff to consider, so any advice would be helpful.
