The Simmons Pro Target Air 3-9x40 Riflescope (Model: SIMSPTA3940) is a precision-engineered optical instrument built specifically to withstand the harsh demands of airgun shooting. While standard rifle scopes are only built to handle rearward recoil, spring-piston and gas-piston air rifles produce a violent, two-way (forward and backward) recoil action that can easily destroy unreinforced optics. The SPTA3940 variant solves this issue with specialized internal spring-piston dual-recoil compensation, housing its reliable mechanics inside a rugged, one-piece 1-inch aluminum main tube.

Key Features of the Simmons SPTA3940:

• Dual-Recoil Compensation: Engineered with internal reinforcements to absorb the unique multi-directional shock curves of spring-piston, gas-piston, and high-power PCP air rifles.
• Fully Coated All-Glass Optics: High-quality glass lenses maximize light transmission, delivering bright, sharp, and high-contrast images during critical dawn and dusk shooting hours.
• Truplex Reticle: Outfitted with a clean, non-illuminated second focal plane (SFP) Truplex reticle for fast, uncluttered target acquisition.
• IPX7 Environmental Protection: Fully sealed and nitrogen-purged housing provides reliable waterproof, fog-proof, and shockproof performance in wet or humid Australian field conditions.
• Dovetail Mounting Rings Included: Ships complete with a set of 1-inch aluminum dovetail rings. These mounts feature an integrated stop pin designed to anchor into the airgun receiver, preventing scope creep under heavy recoil.

Who It Is For:

The Simmons Pro Target Air 3-9x40 is ideal for Australian shooters, farmers, and property owners seeking a durable optic for pest control (such as rabbit and varmint eradication), backyard plinking, and target practice. It is highly compatible with the standard 11mm or 3/8-inch dovetail receiver rails found on almost all air rifles in the Australian market. Because this is an entirely mechanical, non-electronic optical device, it requires no batteries or external power, making Australian electrical SAA/RCM standards non-applicable. Shooters wishing to mount this durable scope onto a rimfire or centrefire rifle utilizing a Weaver or Picatinny base can easily do so by sourcing a separate set of standard 1-inch Weaver-style rings.
