If $150 is the difference between getting rings or not for your gun... as a friend I recommend you find a new sport/hobby. This one is pricey (though much cheaper than racing boats for sure)
Consider the PST Gen 2 for $650-700 new or the Athlon Ares BTR for $550 to save enough $$$ for ammo.
Ultimately, it doesn't matter how much you spend on gear or have if you can't afford to feed the beast.
I'd rather be the guy driving his Miata everywhere (.22LR or .223 trainer) anytime than the guy with the Ferrari in the garage who can't afford even gas for it after making payments and insurance.
Shooting is fun.
Fingering your $$$$ uber gear at home and reading interwebz forums because you can't afford ammo, range or comp fees, gas to drive there, etc. is stupid.
Make sure you're budgeting so that you have the $$$ to shoot.
I say this in a friendly way, not mean or condescending.
That said, I love the Razor Gen 2. But the PST Gen 2 will do the same thing at 1/2 the price with 95% of the glass. Like everything else, you get less for your $$ as you climb the ladder in terms of common sense, but more in terms of specifics to that endeavor.
Good call using quality rings/scope mount. Seekins, ARC M10, NF unimount, badger or NF rings... all great
