Update, new equipments and now asking whats next to grind

Now i have fully fitted myself, im 3 stars now

  1. P90 for close quarters (ambushing trucks in El Chara) Long Barrel, Muzzle Brake, Reflex

  2. M24 for long ranges (killing the humvee gunner in Fort Ronograd) Long Barrel, Magazine Exterior, 8x Scope, Muzzle Brake

  3. Glock for panic attacks (when i ran out of boolets or cqb in sniper) 33rd mag

I also have a Dual PVS-14 enabling me to fight in the dark

Should i grind for a stryker? Or littlebird? They seem to have their perks, but little bird can give me access to high places like mountains, right? And it can fly me to easy sniping areas, plus i doubt ill need a stryker, im a solo player, jeep is already small and fast, whats your say?
