Buying a stock before checking barrel contour leaves fit unconfirmed.
With a Remington 700, that can cost time, money, and consistency. The barrel channel has to provide enough clearance for the barrel contour and match the stock maker’s barrel-channel specification.
Measure the barrel diameter at multiple fixed points and compare those measurements to the stock maker’s barrel-channel specification.

Why barrel contour matters for stock fit
Barrel contour is the taper and diameter profile of the barrel. A sporter barrel, a medium contour, and a heavy or varmint barrel do not sit in the same channel.
If the channel is too tight, the barrel can touch the stock once the action screws are torqued. As the barrel warms, or as the stock flexes under torque, bipod load, or field pressure, minor clearance issues can become intermittent contact.
The standard is direct: measure the barrel first, then match the stock to the barrel that is actually on the rifle.
How to identify sporter, medium, and heavy contours
Most Remington 700 barrels fall into three practical categories for stock selection.
Sporter contour
- Light profile
- Common on hunting rifles
- Usually slimmer near the fore-end
Medium contour
- Heavier than a sporter profile
- Common on crossover hunting / precision builds
- Requires more channel clearance than a sporter barrel
Heavy contour
- Thick profile for precision or sustained fire
- Often described as varmint or bull-style in general use
- Requires the most clearance
These are practical fit categories, not universal industry standards. Visual comparison is not enough. Two barrels can look similar and still differ enough to change stock fit.
Tools you need to measure accurately
Basic measurement tools are enough:
- Calipers for outside diameter
- A ruler or tape to measure from the receiver consistently
- A notepad to record each measurement
- The stock maker’s contour chart or barrel-channel specification
Measure the barrel at the same reference point every time. A common starting point is just forward of the receiver, then a second point farther toward the muzzle to confirm taper. Record the numbers in inches or millimeters and keep them with the rifle’s model and barrel length.
That produces a measured profile rather than a visual estimate.
Common fit mistakes that cause barrel-channel contact
The most common mistake is buying a stock by rifle name and stopping there.
A Remington 700 action can sit in many different barrels and configurations. A stock that works for one build may not clear another.
Watch for these errors:
- Assuming all Remington 700 barrels use the same contour
- Measuring at one point and ignoring taper
- Forgetting that action torque can pull the barrel into the channel
- Ignoring how a hot barrel can shift contact during strings of fire
- Choosing a stock that is cosmetically right but geometrically wrong
Check the barrel channel with the barreled action seated in the stock before final assembly. The goal is consistent clearance, not appearance.
When to choose a stock with more clearance
More clearance is the right call when the barrel is not a standard sporter profile, when the rifle is built for longer strings, or when the stock maker recommends a broader contour range.
Choose a wider channel if:
- The barrel measures closer to a medium or heavy contour
- The build uses a thicker aftermarket barrel
- The intended use involves more sustained heat
- The stock maker’s barrel-channel specification calls for additional clearance
The goal is straightforward: maintain clean separation between barrel and channel while following the stock maker’s fit specification. More clearance is not the same thing as the correct barrel channel for that stock system.
A simple final check before you order
Before ordering, confirm three things:
- Barrel diameter measurements
- Stock contour compatibility
- Intended use: hunting, precision, or mixed field work
If those three line up, the risk of barrel-channel contact drops significantly.
FAQ
What is the easiest way to identify my Remington 700 barrel contour?
Use calipers and compare the barrel diameter to the stock maker’s contour chart. Visual inspection alone is not reliable.
Does a tight barrel channel hurt accuracy?
It can. If the barrel touches the stock under torque or heat, point of impact can shift and repeatability can suffer.
Can I use a stock made for a sporter barrel on a heavy contour?
Usually not. Heavy contours need more clearance, and forcing the fit can create barrel-channel contact.
Should I leave extra clearance for a hunting rifle?
A small amount of clearance can make sense, but the channel still has to match the contour range the stock maker specifies. More clearance is not the same thing as the correct barrel channel for that stock system.
What if I am still unsure after measuring?
Compare the measurements to the stock specifications before ordering, or choose a stock platform with a clearly documented contour range.
