The Crimson 3 reticle is a holdover reticle not one designed for clicking. It is challenging to find an inexpensive scope with good glass and reticle that will hold up to lots of clicking. They have to cut somewhere in those to keep the cost down. It really depends on how much you will be clicking. Once every two weeks for an hour or every day for 3 hours a session?
 
Bought mine from Extreme Tactical in Jan 2021 and did take about 3 weeks. Others have already commented on glass quality. After using it for a couple months, I too hate the turrets.

The locking turrets don't positively click into either lock or unlock position, causing unexpected lock-up while adjusting elevation. For <$200 it's still fun, doesn't bother me for target shooting. Focus and power adjustment knobs are good. Wouldn't plan on quickly dialing for elevation while hunting though. 
 
I purchased 2 Alpha 6 scopes after reading Odoyle’s comments (as well as those of others). I have been very happy with them, although I do agree with all the comments that their turrets are not the best. They do work, but can be a little mushy. On the other hand, the glass is good and clear and the eye relief is simply great. At the price the 4.5-27X50 is very hard (probably impossible) to beat.

Having said that, I also own 5 Athlon scopes. 2 Ares 4.5-27, 2 Helos 6-24 and 1 Argos BTR 6-24. I absolutely love them all. The turrets are definitely better than those of the Alpha 6, the glass, to me, about the same. However the Athlons are all First Focal Plane, and cost from 2.75X to7X the price of the Alpha 6.

You pays your money and makes your choice....

I don't know if anyone has ever checked the turret accuracy on the Alpha 6. I would like to see any testing if someone could post a link or just your experiences. Given that most airguns shoot at average PCP speeds of 850-900 fps, that's only 4 mils/40 clicks of holdover. Shooting at 50 yards is usually half a mil or .5 clicks of holdover. I'm wondering if that's too much for the Alpha 6 to handle.
