Re: mk4 vs. ior
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: ffhogue</div><div class="ubbcode-body">...i like the mk 4 4.5-14x50's. if you dont mind buying used, ior scopes can be found for reasonable prices, while leupolds, as usual, will go for so close to what they are new that i usually prefer to just buy them from the store... but there is always the odd good deal on one... keep your eyes open and jump if you find one. </div></div>
What ff is saying is that a Leupold will hold its resale much better. Was watching a new/like-new IOR 2-12x 35mm on ebay last week. It went for $702...
That is about a 50% haircut, some would say a scalping, on the resale from new. If you buy used, seems the way to go; but probably need to investigate the warranty as a 2nd owner before you buy.
ETA: No warranty concerns for any owner, ever, from Leupold.
If you can afford to buy new IOR, and won't worry about a 50% loss on trade or outright sale; probably better off to pony up the extra $$ for a Nightforce NXS and have gear that will perform and keep's its value.
Then there are performance issues... The Mk4 6.5 and 4.5 50mm scopes have 90moa and 100moa of reticle adjustment, the IOR are 50 or 60 IIRC. Divide those #s in half unless you go 30 or 25moa angled scope base which costs you another $150 to $200 for a good one. The Mk4 probably won't need the base, especially if shooting a magnum or flat shooting 6.5 or 6mm.
ETA the ebay auction:
