Description
Getting steady behind the rifle comes down to a good rest, and the Allen 18420 gives you a customizable one at a price that won't sting. This ships empty and lightweight, which means you get to decide exactly how it feels. Poly beads keep it light enough to haul out to the field, while sand or heavier media locks it down for serious bench work. That flexibility is the whole point, and it's why a fill-your-own bag tends to outlast the pre-filled kind that never quite matches your setup.
What Sets the Allen 18420 Bench Bag Apart
The cradle surface has a slightly tacky feel to it, so your firearm settles in and stays put instead of sliding around when you're lining up a shot. The forend rides in that soft channel and the bag molds around it, giving you repeatable placement round after round. Underneath, a slip-resistant fabric bottom fights the tendency to creep across a smooth bench or tailgate, which keeps your point of aim honest.
Filling Your Allen Shooting Bag the Right Way
A collapsible funnel comes in the box, and there are top-mounted spouts that make loading your chosen media painless. Once it's filled, hook-and-loop straps seal everything up tight. Most folks reach for poly beads or plastic pellets since they hold their shape, don't attract critters, and shrug off moisture, but sand, dirt, rice, or whatever you've got on hand will all work depending on the weight and firmness you're after. Heavier fills give you a rock-solid platform, lighter fills make it easier to pack and carry.
Built From 600D Polyester
The outer shell is rugged 600 denier polyester with water-resistant qualities, so it takes range abuse and rough handling without falling apart. It measures roughly 9.5 inches long, 6.55 inches wide, and 7.5 inches high, a handy footprint that supports rifles and shotguns alike without taking over your whole bench. For zeroing a scope, load development, or just a fun afternoon punching paper, it earns its spot in the gear bag.

Frequently Asked Questions
Does the Allen 18420 come with fill material?
No, it ships unfilled on purpose so you can dial in the weight and feel yourself. A collapsible funnel is included to make loading easy. You'll add your own poly beads, sand, or other media through the top spouts.
What's the best material to fill this bench bag with?
Poly beads or plastic pellets are the popular pick because they hold their shape, stay light for carrying, and won't absorb moisture or attract rodents. Sand or other heavier media gives you a more solid, planted platform if steadiness matters more than portability. Many folks mix fills to strike a balance between weight and stability.
Will the Allen bench bag work with both rifles and shotguns?
Yes, the soft cradle accommodates a range of firearm sizes and the tacky surface helps hold the forend steady. It's sized for benchrest and field use at roughly 9.5 inches long. It works well for zeroing optics, load testing, or general range time.
How durable is the exterior?
The shell is built from rugged 600 denier polyester with water-resistant qualities, so it stands up to regular range use and rough handling. The slip-resistant bottom keeps it from sliding on the bench. It's made to take a beating and keep going.
