The scope I am using here is a Primary Arms SLx 1-6x24mm SFP Rifle Scope Gen III - Illuminated ACSS-5.56/5.45/.308 scope. I use this scope on a real AR-15. I put it on this gun to do some testing of the gun. It works fine for this, as airsoft sniper rifles do not shoot that far compared to a real gun. However, this is a $290 scope. I would not recommend buying this nice of a scope to use on your airsoft sniper rifle. A cheaper scope would do just fine for airsoft.
