What SP said…you will probably have to add/change some hardware. It isnt hard. Also, i personally do not like bungee slings. A standard adjustable sling (like magpul, bfg, etc.) Works better for me.
With that rifle you have a QD hole on each side of the rail near the upper. The slot in the stock is how you attach to the back. So find a sling with a single qd point (or find a sling with no attachments and buy one separately that you can add).
personally im against bungiee slings as well. I like aa good 2 point or 3 point convertable sling. Sherriff of Baghdad makes a great 2 point sling, and believe it or not Magpul’s ms3 ms4 line is pretty good too in my experience. I’ve also heard a few folks say Vickers slings are good, but i havent used one yet.
this could be an opportunity for PSA to put together a simple ‘All things AR’ manual (PDF and individually linked chapters) for basic/newbie items like butt stock swaps, gas block adjustments, sling attachments, front site post adjustments, etc. - sort of like a manual or arms but much more basic with pictures!
