Outdoor Life published a step-by-step guide on Nov. 3, 2026, explaining how to mount a precision riflescope. It covers leveling the rifle and reticle, setting scope height and eye relief, and tightening fasteners to manufacturer specifications.
Outdoor Life published a step-by-step guide on Nov. 3 explaining how to mount a precision riflescope, emphasizing that the rifle and reticle must be level, the scope must have suitable height and eye relief, and fasteners must be tightened correctly. The instructions matter to rifle owners because errors in mounting can affect fit and alignment; the report advises following the scope and mount manufacturers’ torque specifications.
The guide recommends securing the rifle in a padded bench vise or a stable gun cradle, then using a bubble level to level the action. It suggests placing the level on a flat surface such as the top of a Picatinny rail. With the scope in its rings, the fasteners should initially be loose enough to allow hand adjustment. A level on a flat spot of the elevation turret can help orient the reticle; the guide also describes aligning the vertical crosshair with a plumb bob while the rifle is level.
Once the reticle is aligned, the shooter should check scope height and eye relief. The guide says the objective bell must clear the barrel and the eyepiece should not be cramped. Its general clearance rule of thumb is a gap of about 0.25 to 0.5 inches between the objective bell and barrel, while noting that rifle and stock profiles can call for a different fit.
For eye relief, Outdoor Life recommends getting into a prone shooting position, closing the eyes, placing the cheek on the stock, then opening the eyes. The view should be clear and centered without moving the head. The article advises tightening ring and base screws with a torque wrench and checking the hardware maker’s instructions. It offers about 20 inch-pounds for ring screws and 30 inch-pounds for base screws only as rules of thumb, not universal specifications.
Mounting Checks That Affect Fit
A scope mount connects the optic to the rifle, so leveling, fit and fastener tension all affect how securely and consistently the setup sits. A reticle that is not level with the rifle, poor eye relief, or a scope positioned too high or low can make it harder for a shooter to achieve a natural, repeatable position. The guide presents these checks as part of mounting, not a substitute for sighting in the rifle or confirming its performance at a range.
The torque advice is especially relevant because fasteners and mounts can differ. The article gives approximate values, but explicitly points readers toward manufacturer guidance. Using a torque wrench and tightening screws gradually in an alternating pattern can help distribute pressure across the rings, according to the report.

A Guide in a Precision-Rifle Series
Outdoor Life describes the article as the first installment in a seven-part series about using precision riflescopes and shooting to a rifle’s potential. Its focus is the mounting process: securing the rifle, aligning the reticle, finding a usable position for the scope, and tightening the hardware.
The report notes that rifles with Picatinny rails can offer more flexibility in moving a scope forward or backward to establish eye relief. Adjustable cheek pieces and length-of-pull settings can also help some shooters fit behind the optic. These features do not remove the need to check clearance and alignment on the individual rifle.
“The reticle needs to be level with the rifle.”
— Outdoor Life
Torque Values Are Not Universal
The guide’s suggested torque figures are rules of thumb. It does not establish that the same values apply to every scope, ring, rail or rifle, and it advises checking manufacturer specifications. Readers should not treat the approximate figures as a replacement for instructions supplied with their equipment.
The article also says scope clearance depends on the rifle’s barrel and stock profile. It does not provide a single height or eye-relief measurement that will fit every shooter. The report offers general checks, but the appropriate setup is specific to the equipment and the person using it.
Check Fit Before Range Use
The next step for readers following the guide is to check the optic and mount makers’ instructions, then confirm that the rifle is secure, the reticle is level, the view is clear from the intended shooting position and the fasteners are tightened to the specified torque. After mounting, the rifle still needs to be sighted in and its setup checked safely at an appropriate range.
Outdoor Life presents this as the opening article in a seven-part series. The source does not give a publication schedule for the remaining installments.
Key Questions
What are the main checks when mounting a riflescope?
Outdoor Life highlights reticle alignment, scope height, eye relief and fastener tension. The rifle should be held securely while being leveled and adjusted.
What torque should I use on scope-ring screws?
The article gives about 20 inch-pounds as a rule of thumb for ring screws and about 30 inch-pounds for base screws. It advises checking the manufacturer’s specifications because appropriate values can vary.
How can I check eye relief?
The guide suggests settling into a prone position with the cheek on the stock, closing the eyes, then opening them. The view should be clear and centered without shifting the head.
How much clearance should there be between the scope and barrel?
Outdoor Life offers 0.25 to 0.5 inches between the objective bell and barrel as a general rule of thumb. The rifle’s profile may require a different clearance.
