Description
The BSA Outlook AIR39X40AO is a 3-9x x 40mm AO airgun scope from BSA built on a 1″ tube with a Mil-Dot reticle.
BSA Outlook AIR39X40AO Overview
An airgun scope is built to handle the unusual two-way recoil of spring-piston air rifles and to focus close, since most airgun shooting happens inside 50 yards.
Spring air rifles are notoriously hard on scopes, so stick with optics rated for airgun use on those rifles.
Optics and Reticle
Magnification runs 3-9x with a 40mm AO objective lens. The distributor lists a field of view of 11 – 34.50 ft @ 100 yds. The reticle is listed as Mil-Dot. Lens coating: Fully Multi Coated.
In a second focal plane scope the reticle stays the same size as you zoom, which keeps it easy to see at low power. Holdover or ranging marks are only exact at the magnification the maker specifies, usually the highest setting.
Turrets and Adjustments
Adjustments move 25 MOA per click with 35 MOA of total elevation and 35 MOA of windage. Parallax: 10 yds to Infinity. Zero the turrets at your chosen distance and note how many clicks you need for longer shots.
Mounting and Fit
The 1″ main tube needs matching 1″ scope rings or a one-piece mount. Eye relief is listed as 3.70″ – 4″, so set the scope far enough forward that recoil cannot drive the eyepiece into your brow, then level the reticle and confirm you get a full sight picture with a natural cheek weld. Listed length is 11.75″.
Build and Durability
The tube is aluminum, finished in matte black, and the distributor lists it as fog proof / shockproof / waterproof. Listed weight is 12.30″. Check ring screw torque after the first range session and again before hunting season.
Honest Limitations
Every scope involves trade-offs. More magnification brings a narrower field of view, more visible shake and more heat mirage on warm days, and a larger objective adds weight and height over the bore. Budget and mid-priced scopes can be excellent values, but their adjustments and low-light performance do not match premium glass, so match the scope to how and where you hunt or shoot.
Low-light performance depends on the objective size, coatings and your own eyes as much as the spec sheet, so compare scopes at dusk if you can.
Sighting In
Bore sight first, then fire a three-shot group at 25 yards to get on paper and move to 100 yards to refine. A 100-yard zero is the common starting point for centerfire hunting rifles, 50 yards for rimfires, and the distance your ballistic data assumes for long-range work. Confirm the zero with the exact ammunition you plan to use.
Care and Storage
Keep lens caps on in the field, clean the glass with a lens brush and microfiber cloth instead of a shirt tail, and store the rifle where temperature swings will not fog the optics. Recheck zero after any hard knock or after travel.
Before You Buy
Confirm the ring size, mounting height and the distances you shoot most. Riflescopes are not firearms and ship without an FFL transfer.
