I have three. Two were bought at the pre-intro order price and one was bought out of the PX, without illum., for $800.00 NIB. I don't think think there is one currently for sale in the PX. A search of the PX will show a number of sold units from this year which will give you pricing. If the seller is in the $800. range for the non-illum and in high condition it's gone. The same criteria for illum. at $850.-900. and it's gone.
The 5-20 needs a throw lever, parallax assist and zero stop shims for ease of use. Search the scope section for
@Tyler Kemp and
@TimK . About a $100.00 will get you everything you need. The warranty is life time. For tech advice they have a great guy in Skylar. You get 10mil turrets. The glass is good++.
@lowlight uses/used one for a loaner in his classes. They are mechanically acccurate and robust. They sold plenty of them so their track record is known and they have about 30mils of elevation adjustment. The reticle is the one thing that is a question. It is not too fine for 5 and not too coarse for 20. I dial elevation and hold wind and I have not found it to be an issue.
The current crop of scopes available in the $1K range can make the argument that there may be a better place to spend your money. I honestly don't know. And, that is the reason you see so few of them in the PX. They are tried and true like an old friend. No one is perfect and no friend is perfect. The human condition is such that we seek perfection but are disposed towards familiarity and reliability.
Consider that three of the posters have said that they have them and all three still own them. Two of the three have said that they would choose something different in today's market. None the less, one is a backup to a backup and the other is still on a rifle that I am assuming the poster still uses. They seem to agree that in the current market there are options that they would try at the "retail price of the 5-20". So obviously the question becomes who would by one at the regular price? Again I don't know but I still see them as a value at the Black Friday prices and at the demo prices that SWFA occasionally has. Can you sell it for what you payed for it? Not for what you payed for it? Are you going to lose your butt? No. Will it be saleable if you decide to move it on? Yes. If you buy based on the PX pricing you would have to be desperate to lose more than a couple of hundred bucks.
There is still a place for the 5-20 in today's market. If you've never had a scope in over the $5-600.00 dollar range you will see a significant improvement. Second, if the confusion of all the new stuff available leaves you in a quandary then buy the 5-20 and get to shooting. When you get the scope do a tracking test. Put at least a hundred rounds under it and make sure the controls are OK with you and that you can live with the reticle. If you are you reading this thread you know that there are five to ten guys here that are scope geeks. It's either because it is part of their profession or it is their passion. In both cases they know of what they speak. Read everything they have to say and file it away. When the time comes, and it will, to move on to something other than the SWFA you will be well informed and in all likelihood you'll keep your 5-20.......Like the rest of us.
