Athlon is my favorite current scope company. Great glass for the price, super service and warranty.
The Argos is a good scope, but does lose some clarity and brightness at higher mag. The Arken sh4 was much brighter, and just as nice glass, but it’s a beast in the weight department. Of you’re going to be shouldering your gun, you might want the athlon, purely to keep weight to a min. The heavier the scope, the more top heavy your rifle, and the more cant becomes an issue. If you’re benching or using from a tripod, it doesn’t matter.
