Vortex Strike Eagle vs SIG Tango MSR: Budget LPVO Compared

Buy the SIG Tango MSR 1-6x24 if you want the LPVO most builders pick and you're on a tight budget. Buy the Vortex Strike Eagle 1-8x24 if you want 8x. Between them, these two lines account for over half of all LPVO picks on GunPartPicker.

The short answer

Most picked LPVO: SIG Tango MSR 1-6x24. About one in four of every LPVO pick last quarter went to this one scope, and it's around $210 today.

• What we like: 1-6x with an illuminated BDC6 reticle for about the price of a mid tier red dot.
• Watch out for: second focal plane, so the BDC holds are only right at 6x.

Best 1-8x: Vortex Strike Eagle 1-8x24. The most picked 8x LPVO on GunPartPicker by a wide margin, around $340 today.

• What we like: 10 inches long, about 17.6 ounces, and the AR-BDC3 reticle is laid out for common 5.56 loads.
• Watch out for: usually sold without a mount, so budget another $50 to $150.

Best 1-10x: SIG Tango MSR 1-10x26 FFP. Around $600 with SIG's cantilever mount, and the 10x Strike Eagle is out of stock everywhere we track this week.

• What we like: first focal plane, so the holds work at any magnification.
• Watch out for: a 34mm tube and about 21.9 ounces, heavier than any 1-6 or 1-8 here.

What builders mount

Tango MSR picks are mostly the 1-6x24. Strike Eagle picks are mostly the 1-8x24. So in practice the matchup builders are making isn't 1-6 against 1-6. It's a $210 SIG 1-6 against a $340 Vortex 1-8.

Specs side by side

Specs come from the makers' dealer listings, which disagree by an ounce here and there. SIG's 1-8x24 price includes its Alpha MSR cantilever mount.

Tango MSR 1-6 vs Strike Eagle 1-6

The two 1-6 scopes are close. Both are 30mm, second focal plane, illuminated and about the same weight.

The Tango MSR gives you a little more eye relief, which helps when your head isn't perfectly placed. The Strike Eagle 1-6 is a bit cheaper today, but it's in stock at only one merchant we track. Builders pick the SIG by a huge margin, and we'd go the same way.

Tango MSR 1-8 vs Strike Eagle 1-8

Here the Vortex wins on picks. Our builders choose the Strike Eagle 1-8x24 several times as often as the Tango MSR 1-8x24.

The SIG includes a mount, which narrows the price gap once you add one to the Vortex. The Strike Eagle's AR-BDC3 reticle is etched for 5.56 drops out to 650 yards. If you already own a mount, we'd buy the Strike Eagle.

Do you need 8x or 10x?

Most people don't. A 1-6 covers home defense, carbine classes and steel out to 400 or so.

8x helps if you shoot small targets at 300 to 500 yards. 10x and first focal plane start to matter if you dial or hold at long range on every magnification. Each step up adds weight and cost. The 1-10 Tango MSR is the heaviest scope on this page.

Which mount to put it on

Every scope here has a 30mm tube except the 1-10 Tango MSR, which needs 34mm rings. Buy the ring size that matches before anything else.

On an AR-15 you want a one piece cantilever mount. It pushes the scope forward over the handguard so you get the eye relief right with your cheek on the stock. Most LPVO mounts sit the center of the scope about 1.5 to 1.93 inches over the rail. Taller mounts let you run your head more upright, and lower ones give a firmer cheek weld.

If you buy the Strike Eagle, add a mount to the cart. If you buy a Tango MSR with the Alpha MSR mount, you're done. The optic mount guide has the mounts builders pick.

Second focal plane, briefly

All four 1-6 and 1-8 scopes here are second focal plane. The reticle stays the same size as you zoom. That keeps the center dot easy to see at 1x, but the BDC holdover marks are only correct at max power.

Run them at full magnification when you use the holds, and you'll be fine. The zero guide explains why an LPVO usually wants a 100 yard zero.
