The scope decision can break a precision budget. It's also where a lot of shooters lose money twice: they buy cheap, discover the turrets don't track, then buy again. This comparison looks at three scopes from three very different tiers: the Sig Sauer Tango-MSR 3-18x50 as the budget entry, and two flagship-class competition scopes, the Burris XTR Pro 5.5-30x56 and the Trijicon Tenmile 4.5-30x56. It isn't about which is "best." It's about which one matches your shooting and your wallet.
Specs below come from manufacturer and retailer listings, and several of these scopes have multiple reticle and focal-plane variants. Confirm the exact configuration on the listing before you order. This is a spec-based buyer's guide, not a tracking test.

Why focal plane is the first question
On a first focal plane (FFP) scope, the reticle scales with magnification, so your holdovers are correct at any power. On a second focal plane (SFP) scope, the reticle's subtensions are only true at one magnification, usually the maximum. For precision shooting where you hold wind and elevation, FFP is generally the better tool. SFP is fine if you dial every shot and keep the scope on one power. Whatever you buy, make sure the reticle and turrets use the same units. Our MOA vs MIL guide explains why that matters.
Sig Tango-MSR 3-18x50: the budget entry
The Tango-MSR line is Sig's value tier. The 3-18x50 is a sensible magnification range for a first precision rifle out to intermediate distances. It's a good fit if you are pairing glass with a Tikka CTR or similar rifle and want to shoot now rather than save for a year. The honest limits of a budget scope are glass quality at the top of the magnification range, low-light performance, and how precisely the turrets track over large adjustments. Test the tracking yourself: dial a measured amount and confirm the impact moves by the same amount. Our sister site has a full Tango-MSR 3-18x50 buyer guide with more detail.
Burris XTR Pro 5.5-30x56: built for match day
Burris markets the XTR Pro directly at PRS and NRL-style competition, and says it is designed and made in Greeley, Colorado. Listings show a 34mm tube, first-focal-plane reticle options, 0.1 mil clicks on the MIL version and parallax that adjusts down to 20 yards. Its competition-specific features include a quick-detach race dial and a tool-less zero stop, which help if you run different dope cards for different stages. At about 33.6 ounces listed, it's heavy, which is fine on a competition rifle and a burden on a carry rifle.
Trijicon Tenmile 4.5-30x56: long-range flagship
Trijicon calls the Tenmile 4.5-30x56 its flagship long-range riflescope. Listings show a 34mm tube, extra-low-dispersion glass, a zero stop, and dual red/green illumination on the FFP models, which offer MOA or MRAD Precision Tree reticles. Retail listings show roughly 29 mrad of elevation travel on the MRAD version. That's generous for long-distance work, especially with a canted base. The Tenmile makes the most sense on a rifle that will shoot far and often, such as a PRC-chambered rifle.
Which one should you buy?
- First precision rifle, limited budget: the Tango-MSR. Put the savings into ammunition and a class.
- You shoot matches and plan to keep doing so: the XTR Pro's competition features pay off on the clock.
- You shoot far, hunt and compete occasionally: the Tenmile's glass, travel and illumination make it a do-everything flagship.
Mount it like it matters
Both flagships use 34mm tubes, so buy rings in the correct diameter and torque them to spec. A scope that shifts under recoil makes any glass useless. Check your ring height against your cheek position so you can see the full picture without lifting your head.
Buy the Tango-MSR if you want to start shooting now, the XTR Pro if you compete, and the Tenmile if you want one flagship to do everything. Whichever you choose, confirm the focal plane and units on the listing, match your reticle to your turrets, and torque your rings.
FAQ
Is first focal plane better for precision shooting?
For holding wind and elevation at different magnifications, FFP is generally better because the reticle stays accurate at any power. SFP works if you dial and shoot at one set magnification.
Is the Sig Tango-MSR 3-18x50 good enough for PRS?
It's a budget entry that can get you started. Serious competitors usually upgrade for tracking consistency, glass quality at high power and competition turret features.
Do the XTR Pro and Tenmile use 34mm rings?
Listings show 34mm tubes for both. Confirm the specific model, then buy rings of the matching diameter.
MIL or MOA?
Either works if your reticle and turrets match. MIL is more common in competition, so shared dope and coaching are easier to use.
