ADJUSTMENT
Your R.A.S.S. Bench is fully adjustable to fit most shooters. The seat height above ground is adjustable. The seat distance from the
center post is adjustable. Rifle torso height above the seat is also adjustable.
RCBS has found that the seat height adjustment of second from the top to be the most comfortable position for most shooters. If you
desire the seat to be higher or lower, support the Seat assembly and remove the Quick Pin and adjust the Seat Hub Bracket up or down
and reinstall the Quick Pin.
Adjust the Seat distance from the post to a comfortable position. To do this, tip the Seat forward towards the Center Post, press down
to disengage the bottom adjustment and slide forward or back. Return the Seat back to horizontal.
The Rifle Rest has been designed to fit most bolt action, lever action and semi-automatic rifles. There are three rear adjustment points
with 3” of vertical adjustment that allow you to place the butt of the rifle exactly where you want it. The Front Rifle Rest has 7” of
horizontal placement with 8” of vertical adjustment.
The Rifle Rest has been designed to allow you to cycle a lever action rifle without having to reposition the rifle. This same design
feature allows you to change magazines on semi-auto rifles without having to remove the rifle from the Rest.
Once you have adjusted the Rifle Rest to your rifle, you can adjust for torso height by, locking the Pivot Cam Lever, loosening the
upper knob, lifting and rotating the rifle rest and changing to a new position. RCBS has found the middle position to be the most
comfortable for most shooters. Individuals with a long or short torso may want to adjust up or down accordingly.
The Rapid Acquisition Lever allows you to rapidly adjust from a horizontal position to +/- 20 degrees. The fine adjustment knob
allows for precise vertical aiming (see Photo 12). WARNING: THE RAPID ACQUISITION LEVER SHOULD NOT BE
ENGAGED UNLESS THE USER IS PROPERLY POSITIONED ON THE REST. FAILURE TO COMPLY COULD CAUSE THE
FIREARM TO FALL FROM THE REST CREATING AN UNSAFE FIREARM CONDITION THAT MAY CAUSE PROPERTY
DAMAGE, PERSONAL INJURY OR DEATH.

The Rifle Rest can rotate independently or with the Seat to allow for a 360 degree field of fire.

horizontally, without the Seat moving.
For combined rotation of the Rifle Rest and Seat, sit on the Seat and sight through the rifle. Lock the Cam Lock Lever. The Rifle Rest
will now rotate with the Seat around the centerline of the Hub.
The Legs of the R.A.S.S. Bench have three adjustment points. The innermost position is for storage and transport. The Legs should be
adjusted to the middle or extended position for greater stability remove the Quick Pin and adjust each Leg out to the desired position
and reinstall the Quick Pin.

the Ammo/Spent Case Tray. Tighten the Cam Lock Lever, loosen the lower Center Support Knob and lift off the upper part of the
Rest as a unit. This unit can be further broken down by loosening the Cam Lock Lever and separating the Rifle Rest from the Center
Support. Adjust the Legs to the innermost position to minimize the size of the lower unit for transportation. Orient the Seat to the
