A bases and rings "How To" guide.
A FEW POINTERS ON HOW TO CHOOSE THE RIGHT BASES AND RINGS FOR YOUR SCOPE AND RIFLE.
Choosing the right rings. One of the most common questions asked to our customer service department is "how do I determine which bases, rings, and rails are appropriate for my rifle?" This also applies to scoped shotguns, in some cases. The answer is often difficult and a bit complex for several reasons.
- Several types of bases and rings are offered for Browning rifles, such as 1) integrated, 2) separate bases and rings and 3) Weaver style rings that mount on a rail base, among others.
- Scopes are sold with objectives (front bell) that vary in diameter all the way up to a 56mm objective. Historically, hunting objectives were so small that they rarely created a problem.
- Scopes vary in length which can result in the objective being closer to the chamber portion of the barrel (which is a larger diameter).
- Adjusting for eye relief can affect where the objective sits in relation to the barrel.
- Sloped or canted rails are available (usually 20MOA) that allow a scope to function at longer ranges (600 years and beyond). This also can result in moving the objective closer to the barrel.
- Barrels vary in diameter. A target barrel can be significantly larger in diameter than a sporter barrel, which, in effect, closes the gap between the barrel and objective.
The solution: Rings are sold with different heights to accommodate the objective of the scope. You will not have a problem if you use the correct ring height for your scope. To do this, refer to the guide on this page for making your choice.
It is up to you which type or style to use: separate bases and rings, integrated bases and rings or rings that attach to a single rail or two-piece rail. The important thing is to build a scope mounting system that provides the best accuracy and performance overall. It is possible to damage a scope with the wrong setup. So be careful as you put yours together. THE SCOPE OBJECTIVE SHOULD NEVER TOUCH THE BARREL WHEN MOUNTED ON YOUR RIFLE.
IMPORTANT: There are a great number of variables when attaching scope bases and rings and attaching a scope. These guidelines on this page should be considered as a starting point as you learn what combination of bases, rings, and scope are best for your rifle. Go slow. Don't damage your rifle or scope.
