New Bolt-Action In Hand. Now How Do You Mount Your Scope?
You've got your Remington 700, Winchester Model 70, Ruger American, Savage 110 — or any one of a dozen great bolt-action hunting rifles — and now you're staring at the receiver wondering where to start with mounting your scope. Two-piece or one-piece base? Aluminum or steel rings? What height? This article walks you through all of it, so you can make a confident decision and get out to the range.
Step 1: Pick Your Base Type
The base is the foundation everything else sits on. For bolt-action hunting rifles, there are three common options — and which one is right for you depends on your rifle, your hunting style, and how much you want to tinker.
Maximum Adjustability
One-Piece Rail
A single solid chunk of aluminum running across the entire receiver. Because it's machined as one piece, it's extremely rigid and gives you a long run of slots to position your rings exactly where you need them. Great for larger scopes, adjustable eye relief, or if you want room to add accessories down the road.
The trade-off: it adds a bit more weight and covers the top of the receiver — which can get in the way on rifles that load from the top with stripper clips.
Lightweight & Traditional
Two-Piece Bases
Two smaller pieces — one at the front and one at the rear of the receiver. Lighter and sleeker than a full rail, they leave the top of the action open, which matters on old-school bolt guns that use stripper clips or load from the top. Hunters who count every ounce often prefer this setup.
They're plenty strong for typical hunting calibers, just with slightly less fore-aft positioning flexibility than a full rail.
Already Done For You
Integral Rails
Many modern bolt-action rifles — Ruger Americans, Tikkas, and others — come from the factory with a rail already machined into the receiver or installed by the manufacturer. If yours does, consider yourself lucky. Skip straight to picking your rings.
Just confirm whether it's a Picatinny or Weaver-style rail, as the slot spacing is slightly different and affects which rings will fit.
One-Piece vs. Two-Piece: Side By Side
Still on the fence? Here's how they compare across the factors that matter most to a bolt-action hunter.
| Factor | One-Piece Rail | Two-Piece Bases |
|---|---|---|
| Weight | Heavier — more metal overall | Lighter Win |
| Rigidity | Slightly stiffer — one solid unit Win | Very strong, minimal difference on most calibers |
| Eye Relief Adjustment | More slots = more flexibility Win | Fewer positions, less fore-aft travel |
| Top-Loading Actions | Can block loading port — check before buying | Keeps receiver open Win |
| Accessory Space | More rail real estate for lights, lasers Win | Limited mounting space |
| Traditional Look | Chunky, tactical appearance | Sleek, classic hunting profile Win |
Step 2: Aluminum Or Steel Rings?
Once your base is sorted, you need rings to actually hold the scope. The big decision here is material — aluminum or steel — and it mostly comes down to how heavy your rifle kicks and how much weight you want to carry.
Best For: Mountain Hunters & Weight-Conscious Builds
Aluminum
Roughly half the weight of equivalent steel rings
Modern alloys (6061-T6, 7075-T6) are genuinely tough — not a compromise
Won't rust in rain, snow, or humidity
Similar hardness to aluminum scope bodies — gentler on the tube
Works perfectly for .270 Win, .30-06, 6.5 Creedmoor, and most standard hunting calibers
Can strip threads if over-torqued — use a torque wrench
Best For: Heavy Magnums & Maximum Durability
Steel
Virtually no flex — the ultimate in rigidity
Preferred choice for .300 Win Mag, .338 Lapua, and larger calibers
Handles hard knocks, rough handling, and extreme recoil without complaint
Heavier — noticeable over a long day in the hills
Non-stainless steel needs to be kept oiled to prevent rust
Great peace-of-mind choice if you want zero compromise on strength
Step 3: Match Your Setup To Your Situation
Every hunter's situation is a little different. Here's a straightforward guide to help you match the right hardware to your specific needs.
Base
Two-piece aluminum bases — lightest setup possibleRings
Aluminum rings — save weight without sacrificing performanceBase
One-piece rail — maximum rigidity under heavy recoilRings
Steel rings — unmatched strength when recoil is severeBase
Two-piece bases — keeps the action open for loadingRings
Either material works — focus on the base choice hereBase
One-piece multi-slot rail — more positions to dial in eye reliefRings
Any height that clears your objective bell — go as low as possibleBase
Either — focus on the ring choiceRings
Quick-detach rings — swap between optics in seconds without toolsA Few More Things Worth Knowing
Ring height matters. Go as low as you can while still clearing the barrel and objective bell. Lower rings mean a better cheek weld, less wobble, and a sleeker profile. Only go to medium or high rings if your objective lens is large enough to demand it.
Torque to spec — every time. Whether you're running aluminum or steel, rings that are under-torqued will shift and rings that are over-torqued can crush scope tubes or strip threads. A basic torque wrench and a few minutes of careful installation will save you hours of chasing zero problems at the range.
Think about accessories. You're less likely to be mounting lights, lasers, or backup optics on a bolt-action than on an AR — but if you ever think you might want that option, a one-piece rail gives you far more space to work with than two-piece bases will.
Match your hardware to your rifle's action size. Weaver and other manufacturers make bases in short action and long action versions. A short-action base on a long-action receiver (or vice versa) won't fit properly. Know your action length before you order.

There's no single right answer for every hunter — but there is a right answer for your rifle, your hunting style, and your terrain.
Use the guidance above to make a smart choice, install it correctly, zero it at the range, and then forget about the hardware and focus on the hunt.
