Description
The Caldwell Zero-Max is a full-length, no-frills metal rest built for folks who want stability without a lot of fuss. The frame is welded from square tube steel, so it holds its shape shot after shot and shrugs off the recoil of both rifles and shotguns. It runs roughly 23 to 24 inches long and tips the scale around 4 pounds, which makes it easy to carry from the truck to the bench and back. If you've been trying to zero a scope off a rolled-up jacket or a folded towel, this is a big step up in repeatability.
Dialing In With the Zero-Max Rest
Windage and elevation both adjust with knobs placed where you can reach them, so you can nudge your point of aim without pulling the gun off the rest. There's a micro adjustment for fine elevation corrections when you're chasing that last little bit at the target. Worth knowing up front: the two front feet handle most of the elevation work, and some folks like to add a small shim or bag under the rear to fine-tune height on longer strings. It's a straightforward system that rewards a little practice.
The Medium Varmint Front Bag
This version comes with the medium varmint front bag, which cradles the forend of your rifle or shotgun and keeps the finish free of scratches and dings. It attaches to the front rest with hook-and-loop, so swapping or repositioning is quick. At the rear, your buttstock settles into a padded nylon cradle that protects the stock while you shoot. Between the two contact points, your gun sits secure and steady from setup to the last round.
Who Reaches for a Zero-Max
This rest earns its keep at the range for sighting in, working up handloads, function testing a new build, or just burning through a box on a lazy afternoon. Hunters use it before season to confirm zero, and target folks lean on it for consistent groups. It's an ambidextrous, budget-friendly setup that does the important stuff well without the complexity of a full benchrest pedestal.

Frequently Asked Questions
Does the Zero-Max come with the front bag filled or empty?
This configuration ships with the medium varmint front bag unfilled, so you'll fill it yourself before your first range trip. Standard bag filler like ground walnut, polymer media, or fine sand works well and lets you tune how firm you want the front support. Once it's packed, it cradles the forend nicely and stays put.
Can I use the Zero-Max shooting rest for shotguns as well as rifles?
Yes. The tube steel frame is built to handle both rifle and shotgun recoil, and the rear cradle plus front bag support most standard long gun stocks. It's a solid choice for sighting in slug guns or working with a scoped rifle.
How do I adjust elevation on the Zero-Max?
Elevation is set primarily with the front feet, and there's a micro adjustment for fine corrections when you're dialing in a target. Some users like to slip a small bag or shim under the rear support to fine-tune height on longer strings. The knobs sit within reach so you can make changes without lifting the gun off the rest.
Does the rest require assembly out of the box?
There's a little assembly involved. The front frame attaches to the main frame with a carriage bolt and windage knob, and the front bag hooks on with hook-and-loop fasteners. Most people have it together and ready to shoot in just a few minutes.
