The vortex listed from Midway I swear it was listening last week at 379$ and today is was 329$. So I decided I'm doing both the light weight Arken 4x16 and the Vortex. I will be able to compare them side by side. I already did that on my other SH4 Arken and the 50mm Vortex. This one from Midway I think is 44mm objective maybe a 42. But I will replace the Bushnell on my 7mm-08 with the vortex. The Bushnell has been a good scope for what it is and it's been dialing ok but no zero stop. So now that can be a back up or I still have 1 more rifle that doesn't have a scope so it can be put on it probably after the barrel is replaced. Man I wish I had a bore scope. I'm pretty sure there are some cheap ones on Amazon that people say work pretty good. Then I would know for sure on that barrel. Last time I cleaned it; it had a carbon ring in the throat or just a little past. I decided to try and give it another go around and I bought a new wire brush to do some heavy scrubbing and it was stopping pretty hard right past the chamber. Filled barrel full of cleaner and let set over night. A gang pile of stuff came out and no more restriction right past the throat. The gun does have over 4800 rounds down(6.5x284 Norma) the barrel. I would think the barrel is toast. Prior even after cleaning it would open from sub MOA to over MOA. After about 30 rounds. So I just think it's building carbon in the barrel right past the chamber pretty fast. Probably a lot of cracking and worn down lands.
