SIG SAUER TANGO-SPR 4-16x44mm SFP Rifle Scope

SIG SAUER TANGO-SPR 4–16x44mm Rifle Scope

The SIG SAUER TANGO-SPR 4–16x44mm provides a broad magnification range for shooters who need more target detail than a low-power optic can offer. This listing is for manufacturer part number SOTS44000, identified by UPC 798681710768. The exact configuration combines a 30mm main tube, second-focal-plane MOA BDC-1 reticle, 44mm objective, black finish, and included 1.535-inch mounting solution.

At 4x, the scope gives the shooter a practical lower-power view for locating targets and working from varied field positions. Increasing magnification toward 16x reveals finer visual detail for deliberate shots, target evaluation, or range use. The 44mm objective balances light collection with a profile that remains manageable on common sporting and precision-oriented rifles.

Second-Focal-Plane MOA BDC-1 Reticle

The MOA BDC-1 reticle is located in the second focal plane, so its apparent size remains constant as magnification changes. This maintains a familiar sight picture across the power range. The reticle is non-illuminated, making the optic straightforward to operate without batteries or brightness controls.

BDC-style references can assist with holds after the shooter has verified how the reticle corresponds to the rifle and ammunition being used. Because velocity, barrel length, projectile, environmental conditions, sight height, and zero all affect trajectory, the references should be confirmed at the magnification specified by the manufacturer and validated on the range.

Practical Optical Dimensions

The catalog lists the TANGO-SPR at approximately 14.7 inches long with about 3.5 inches of eye relief. That eye-relief distance gives the user room to establish a comfortable head position while maintaining appropriate scope clearance. Proper fore-and-aft placement should be set with the rifle shouldered in the positions most often used before the mounting fasteners are tightened.

The 30mm tube is a widely supported mounting standard and provides a robust central structure for the optic. This exact model is commonly cataloged with a 1.535-inch mount, giving the buyer a compatible installation starting point for a Picatinny rail. Actual clearance should still be checked for the rifle’s receiver, objective bell, barrel profile, and any installed accessories.

Adjustment and Focus

The product catalog lists a 30 MOA elevation adjustment range. Parallax is factory set rather than externally adjustable, reducing the number of controls that must be managed during use. The magnification ring provides access to the full 4–16x range, while the ocular focus should be adjusted until the reticle appears sharp to the shooter.

The black finish produces a subdued appearance that coordinates with typical rings, mounts, and rifle hardware. The scope’s combination of mid-to-high magnification, uncomplicated non-illuminated reticle, and included mount makes it a practical choice for range rifles, hunting setups, and general precision applications.
