Question: Is the tube a 1 inch tube? I did not see this listed
Document: I bought this scope because it has 80 clicks of elevation and 80 clicks of windage. The only other scope (that I foud out later) in this this price range that allows that much adjustment in a 1 inch tube is the ProStaff, but it is bigger and more expensive. Anyway the Redfield was installed on an old Swede 6.5 x 55 sporterized that Bubba had jacked up the mounts so I had to mount high with the mounts that were on the gun.
In fact, I kept it to 50 yards which is the longest range I usually shoot. But with the 7x scope, I think I'll take it out to 100 yards and see what I can do with it. Still, 50 yard plinking will be my typical use out at the family farm so most of my thoughts will be at those ranges.
The ring has a VERY smooth feel with a nice amount of resistance. This scope carries the build quality of a scope far more expensive. One of my only quibbles is the placement of the zoom ring. It's forward of the rear bell and is in a bit of a weird spot because of the knurling on the rear bell. I don't know why there is knurling there (you can see it in the photo) because it serves no purpose.
This scope is a super value for the money spent on it. Glass is crisp and clear and the sight picture is very nice. Even in low light, this scope performs well. I put it on my AR with grand slam ring mounts and couldn't be happier. Zeroing the scope was easy and has a large range of adjustment. My family has a long history with using Redfield scopes and I'm happy to see they have come through one again with this product.
I recently purchased a Nikon M223 1-4x20 Scope for my Ruger Mini 14. The brass was ejecting and hitting the windage turret hard enough that it broke the turret. It's on its way back to Nikon for repair and will probably be used on an AR that I'm currently building.Anyway, that's neither here nor there, but thought I'd share it so you'd know where I'm coming from with optics.
I'll put it on the rifle and get it on a rest to really take a good look through it, but so far, I'm impressed.One thing I really like about the optic (that others may find trivial) is the branding on it. It's subtle and not flashy at all. No chrome or gold or anything weird. There is one logo on the left side of the tube (opposite the windage turret). It's recessed slightly and very small. It's red with black lettering.
I was surprised at the quality of this scope for the money. Good visual field and clarity throughout the range of magnification.
This is a decent scope for the money and has a nice field of view and good eye relief. I would definately recommend it.
This is the second Redfield scope I have purchased and have been extremely happy with both. The clarity and quality exceeds many higher priced scopes.
Really nice design and I really like the simplicity of this scope. It has good glass and a nice clean simple reticle. Bought it during the rebate special.
