Large objective, 7 yard parallax

I'm in the market for a scope for an air rifle. (pneumatic, not spring piston; so recoil is not a worry)
My two main requirements are a relatively large objective for dim light (min. 40mm, prefer 44 or 50) and a parallax adjustment that goes down to 7 yards or lower.
Price: About $400 and down
Magnification: able to do 6x or higher, fixed or variable

There are a ton of scopes that do 10 yard parallax, but a large objective combined with 7 yard parallax seems to be hard to find.

Any suggestions?

(Update: I have found some UTG/leapers stuff, but would prefer other brands. If there's nothing else available, I guess I might give them a try)

If you could settle for a 36mm objective, I would suggest one of the fine old Weaver Target scopes with AO. 8x, 10x, and occasionally 12x, They are $70 to $120 on ebay. The older K8 and K10 are the ones you would need.

Don't get the one with the black rubber/plastic AO ring. You would want the one with AO rings of steel, and 6 screws holding the objective in place. When you see them, it will be obvious.

They have a non-rotating objective lens held in place by a couple of lock rings and a half-dozen very obvious screws that pass through an outer ring, through the scope body, and into the lens cell carrier.

Screw off the outer locking ring, and you'll see how the lens carrier is held in place. Remove the 6 screws and shake out the objective lens carrier. Then with a very small round file, extend each of the slots in which the screws ride, forward, by whatever you think you need. a 0.40" slot length is plenty to give you focus down to 20 feet! Leave yourself some metal. The object is to give that objective lens some more forward travel.

Reassemble the lens cell carrier and 6 screws, screw on the forward lock ring, and give it a try. One of mine will focus just shy of 15 feet. Doing the math, a K10 should give you a 3.6mm exit pupil, a K8 will give you a 4.5mm exit pupil. There was a Burris with a target knob and AO that was popular in Hunter Benchrest. If you find it, I'll be one of those bidding against you!

A problem with low light might show up because these scopes usually have very fine crosshairs. I've never replaced a reticle myself, but these are simple scopes. A fine wire for the reticle, flattened where you want the heavy hairs or post should suffice. Leupold's old 3-9 Compact Airgun and Rimfire scope is usually a bit spendy, but it's almost bright enough at lower power numbers. If you figure out how to get an L.E.D. in there to illuminate those crosshairs you'll have a nice little hobby business whether you want it or not! I have a 1 1/2-6 Burris that serves me well, but without an AO, to eliminate parallax I have to move my head back until the view vignettes, and the resultant "ghost ring" effect isn't that great for low light.

Both Leupold and Burris make very nice scopes for your purpose, but there's lots of stuff out there for less money.
 
Weaver V-16 4-16x42mm Adjustable Objective. Great air rifle scope used by many for years including some of my own that were considered scope killers.
specs show parallax-free view from 30 feet to infinity. pretty sure I used it closer.
Am certain I used the weaver v-7 2-7 at under 20 ft. It is another proven lower cost .22/air rifle scope.
