the SCAR 17 is very sweet, buddy of mine owns one. someone mentioned above about the mags but to be honest i think at first the HK will be hard to snag mags too.. they will both kinda suck in this aspect because they both use proprietary mags. If you really hard up on wanting the MR762 then I would wait, if you are still up in the air though I would just get the SCAR 17. I had the opportunity to get a SCAR 16 and I chose to wait until the MR556 came out because I wanted it that badly. My same buddy also has a SCAR 16 and its a good gun. If i find a great deal on one I think I would pick one up but my point is that I have not one regret about waiting and getting my MR556 it was worth the wait because its what i really wanted! I however with the MR762 am not as excited about it as I was the 556. i am about to be in the market for a .308 battle rifle but I have a couple of projects gun that need work/finishing before I commit to that choice. When i do get to that crossroad if the MR762 isnt released and out to mass market (not just 2 or 3 on GB going for 6K) i wont even second guess getting the SCAR 17. Its that little something different that I would love to add to my gun safe.. in FDE of course. but both would look great in 16 inch barrels in my opinion.
