Quick answer: for a Bergara B-14 used for hunting, a 3-12x or 4-16x scope in the 40mm to 50mm range is the right size, with a 1-inch or 30mm tube. If your B-14 is an HMR, built for both hunting and match-style shooting, step up to a 4-16x or 5-25x with a first focal plane reticle and exposed turrets. The B-14 action takes Remington 700 pattern bases, so mounting hardware is easy to find.
The B-14 line is built for shooters who care about accuracy, and that changes how you should spend. Buyers of a rifle in this class usually put more of the budget into the scope than a buyer of a basic hunting rifle would, because the rifle will shoot tighter groups than a cheap scope can hold. A scope that tracks poorly or loses zero is the first thing that hides what the rifle can really do.
This guide covers the lines (the lighter hunting models and the HMR), which magnification to buy, first versus second focal plane, tube size, how to match scope weight to the rifle, mounting, and what to check when the scope arrives. Most hunting shots are inside 300 yards, and the picks below come from our live US catalog of in-stock scopes in the 3-5x to 14-20x range that suit the B-14.

Match the scope to the model. The lighter hunting versions of the B-14, such as the Hunter, Ridge and Timber, are rifles you carry. Putting a 30mm, 25-ounce scope on one of those makes it front-heavy and awkward to shoulder. A 3-12x42 or 4-12x40 second focal plane scope stays light and handles well. The HMR is the opposite: it is a heavier rifle designed for shooting from a bench, a bipod or a barricade, so a larger 4-16x44 or 5-25x50 scope with turrets you can dial is a natural fit.
Choose the focal plane by how you shoot. On a second focal plane (SFP) scope the reticle stays the same apparent size as you zoom, so it stays bold at low power. Any holdover marks are only correct at one power, usually the maximum. That is fine for a hunter who shoots at 100 to 300 yards and holds center or uses a simple ballistic reticle. A first focal plane (FFP) scope scales the reticle with the image, so its mil or MOA marks work at every setting. That is worth having if you dial or hold over at varying distances on the HMR, at the cost of a finer reticle at low power. For a pure deer rifle, SFP is simpler and cheaper.
Buy the glass and the mechanics you will use. For a B-14 hunting scope, bright multi-coated glass matters most at first and last light, and a clean 4-16x44 is a brighter, more usable scope than a bargain 6-24x50 with the same price tag. If you dial, look for turrets that return to zero after a box test, a parallax adjustment that goes down to at least 50 yards, and a reticle you can read at both low and high power. A quarter-MOA click moves the point of impact about 0.26 inch at 100 yards and a 0.1 mil click moves it 0.36 inch. MRAD pairs well with an FFP mil reticle, while MOA is more familiar to many American hunters, so pick one and keep your whole kit in the same units.
Consider tube size honestly. A 30mm tube has more internal elevation travel than a 1-inch tube, which matters if you plan to dial far out or use a rail with extra slope. It also adds weight and cost. For hunting inside 400 yards a 1-inch tube has plenty of adjustment. If the B-14 is chambered in a cartridge such as the 6.5 PRC or .300 Winchester Magnum and you practice well past 500 yards, a 30mm scope and a 20 MOA base are a sensible pairing. A 20 MOA base tilts the scope down, adding about 21 inches of elevation at 100 yards (20 MOA times 1.047 inches), which keeps the turrets near the middle of their travel at long range.
Mounting is straightforward because the B-14 receiver is drilled and tapped for Remington 700 pattern bases, so the huge range of 700 bases, rails and rings applies. Buy the base for your action length, short or long, since the two are not interchangeable. Pair a one-piece rail with 30mm rings, or use two-piece bases with 1-inch rings for a light hunting build. Torque the screws to the maker's setting, check that the scope's eye box lets you see a full picture the moment your cheek touches the stock, and level the reticle with a plumb line. If the rifle carries a muzzle brake or suppressor mount, remember that it changes blast and noise but not scope selection.
Test on arrival, not on opening day. Look through the scope at a distant edge in daylight, run the power ring through its range, and check that the reticle is sharp when you focus the eyepiece. Zero at 100 yards, then run a box test: dial a set number of clicks up, right, down and left, return to zero and confirm the group returns. Confirm your hold or dial at 200 and 300 yards with the ammunition you will hunt with. An accurate rifle and a good scope remove equipment as a source of error; they do not make a long shot ethical, so shoot only at distances you have practiced from field positions.
A 3-12x42 or 4-12x40 second focal plane scope. It keeps the rifle light and well balanced, gives you a wide field of view at low power, and has enough magnification for careful shots out to 300 yards.
A 4-16x44 or 5-25x50 with exposed turrets, a parallax adjustment and a first focal plane mil or MOA reticle suits the HMR. It is a heavier rifle built for hunting and match-style shooting, so the weight of a larger scope is less of an issue.
The B-14 receiver is drilled and tapped for Remington 700 pattern bases. Buy bases or a rail for your action length, short or long, and check that the listing states B-14 or Remington 700 compatibility.
Not for hunting inside 400 yards. A 1-inch tube is lighter and has plenty of travel. A 30mm tube is worth having if you dial well past 500 yards or use a 20 MOA base with a magnum or long-range cartridge.
Second focal plane suits a B-14 used as a hunting rifle, since the reticle stays bold at low power. First focal plane suits an HMR or any rifle where you use reticle holds or dial at several magnifications.
More than you would on a basic hunting rifle. Most owners do well between about $400 and $900, which buys clear glass, turrets that return to zero and a reticle worth using. Below that, tracking and edge sharpness are where scopes let the rifle down.
A 3-12x or 4-12x covers almost every deer shot. A 4-16x is useful in open country. Keep the scope on low or middle power while you wait, and turn it up only when you have time for the shot.
Only if you shoot well past 500 yards and run out of elevation travel. A 20 MOA base adds about 21 inches of elevation at 100 yards. For deer hunting inside 400 yards a standard flat base is simpler.
