Been using this thing today and it feels alot better than it used too. managed to get a 30-3 FFA on my 3rd time ever on Grind with it among other good games and OSKs don't seem nearly as uncommon as they once did.
I have no idea why the 870 gets labeled as the noob gun with this spam machine in game. Wouldn't go as far as saying its as good as MW3s Striker but there are definitely similarities. Can't wait to try the improved M1216 when I level up.
