Nice that you got a prototype from Jon, great guys (the owners are both named Jon). Some questions I have is that with the Toric 4-20 the turrets had a bit of play in them, have they "fixed" that or does the 4.5-30 also have some wiggle in it? The other issue with the 4-20 was that it had fairly heavy CA so if you have a chance to test that out against your NF ATACR and ZCO I'd be curious how it does (keeping in mind the scope costs half as much as the other scopes I do expect it to not be on par optically but hoping it can hold its own for the price). Another area where the 4-20 struggled was in FOV, how does the 4.5-30 compare to other scopes you have on hand. One of the areas I thought the 4-20 did do fairly well on was DOF so hoping the DOF on the 4.5-30 holds up nicely. I'm sure most of these items will be addressed when you use it in competition as that will be the real test so looking forward to hearing your thoughts after you compete with it.
