Sig TANGO-MSR 1-10x28: What a 1-10 LPVO Gets You
Low-power variable optics (LPVOs) started at 1-4x, moved to 1-6x and 1-8x, and now 1-10x is common. The Sig TANGO-MSR 1-10x28 is one of the more accessible 1-10s. It comes as a package: scope, mount and throw lever. Here's what those parts do and whether a 1-10 is the right choice for your rifle.
What's in the Package
- 1-10x magnification. True 1x at the bottom for close shots with both eyes open; 10x at the top for identifying and hitting targets farther out.
- 28mm objective. Compact at the front of the scope, which keeps weight and height down.
- 34mm tube. A larger tube than the common 30mm, which typically allows more internal adjustment. Make sure any replacement rings or mount you buy are 34mm.
- Illuminated MSR BDC10 reticle. BDC stands for bullet drop compensator: marks below the center that approximate holdover at set distances for a typical load.
- Throw lever. A lever on the magnification ring so you can change power quickly without shifting your grip much.
- ALPHA-MSR mount included. You can mount it on the rifle out of the box.
Sig Sauer TANGO-MSR 1-10x28
A complete LPVO package for a general-purpose AR.
1-6 vs 1-8 vs 1-10
| Range | Strength | Tradeoff |
|---|---|---|
| 1-6x | Lightest, widest eye box, most forgiving at 1x | Less reach for identification |
| 1-8x | Balanced; the common middle ground | Heavier and longer than a 1-6 |
| 1-10x | Most reach for spotting and small targets | Tighter eye box; can be less forgiving at 1x |
The higher the top magnification, the narrower the eye box tends to be, which means your head position has to be more consistent. Take that into account if you shoot from awkward positions.
Using a BDC Reticle Well
A BDC is calibrated for a specific load and barrel length, so the marks are an approximation. Shoot your actual ammunition at the actual distances and write down where it hits. Then you know which mark to use. If the scope is second focal plane, holdover marks are only correct at one magnification, usually the highest; confirm this on the listing and our LPVO guide.
Who It Fits
- A single do-everything AR that has to handle a room and a field.
- Hunters who want a fast close shot and enough power to place shots on game farther out.
- Shooters who find a dot plus magnifier fiddly; see LPVO vs dot and magnifier.
Prefer a dot? Read the Romeo5 Gen II guide. Want more magnification for precision? See the TANGO-MSR 3-18x50 guide. Or browse scopes at Ammunition Depot.
Frequently Asked Questions
Is a 1-10 LPVO good at close range?
Yes, at 1x you can shoot with both eyes open. It is less forgiving of head position than a red dot, so practice fast shots at 1x.
What does BDC mean?
Bullet drop compensator. The marks below the center approximate where to hold at longer distances for a typical load. Confirm them with your own ammunition.
Do I need 34mm rings for the TANGO-MSR 1-10x28?
Yes. It has a 34mm tube. It includes an ALPHA-MSR mount, but any replacement mount or rings must be 34mm.
1-8 or 1-10?
A 1-10 gives more reach for spotting and small targets. A 1-8 or 1-6 is usually lighter and more forgiving. Pick based on how far you actually shoot.
