I have a good leather GI sling on the Socom, I just got an adjustable nylon one today for my AR (no one carries a standard GI sling, and I couldn't get to a gunshow in time...) but my 10/22 doesn't have a sling, in fact, it doesn't even have a stud up front, (it does have TechSights, however!)You planning to shoot the big gun for AS? Do you have a 10/22, if so I'd recommend bringing it along with a brick of CCI low velocity 22LR. Yall are gonna shoot allot of rounds Sat working on NPOA and positions, then Sunday allot more at AQTs. And yes, if you have and or can get a GI web-sling bring it. AS is fundemental "old-school-Army" rifle marksmanship which the web-sling is intregal. If you haven't already, check this out http://appleseedinfo.org/smf/index.php?topic=101.0
