Is there a 250-300$ scope out there with a zero stop?

The Athlon Argos BTR Gen 2 has a zero stop and can be purchased new for $299 on eBay if you are patient. I can’t think of another scope under $300 that has a zero stop, maybe someone else can. 

Cannonball is right, can't think of one. But resettable zero is what is most needed. I have many scopes with zero stop and almost never need it shooting out to 150Y to be totally honest. 

You can make your own "zero stop" in a way. Using adjustable rings, turn your turrets all the way down. Go back up 12-15 clicks to the pressure off the turret spring. Using the adjustable ring with custom MOA set your scope up to zero at your desired distance. Now you have a repeatable zero stop without paying the money. Just click down to zero on your last turn. And you have a ton of elevation to play with for those longer shots. Win Win. Try a discovery and try this techniques, sure it will work for you in the $300 range.

You can always make your own zero stop. guys have been doing it for decades. 

I have seen everything from dimes, to metal washers and plastic washers and o-rings and round holes drilled from cutting boards or other plastics.

I have done it to several scopes with no complaints other then the last shim you use is often the most important and most fussy unless you are ok and sanding your own shim. 

So if there is a scope you really like under $300 but doesn't have zero stop I wouldn't sweat it and just make your own.
