Description
Most shotguns are built for one size of person, and everyone else just makes do. Rock Island Armory took a different route with the All Generations. The buttstock uses a spacer system that lets you shorten or lengthen the pull, so a new hunter still growing into their gear gets the same proper fit as a full grown adult. Pair that with the adjustable cheek rest and you can set up a consistent cheek weld and sight picture for just about anyone in the family. That is a big deal, because fit is what makes a shotgun point naturally and pattern where you look.
What the All Generations 20 Gauge Brings to the Field
The 26 inch barrel wears a vent rib and a front bead, which is exactly what you want for swinging on doves, clays, or a rooster flushing out of the grass. The 3 inch chamber handles everything from light target loads to stouter hunting shells, and the 5+1 capacity keeps you in the game when birds are moving. Rock Island includes full, modified, and improved cylinder choke tubes, so you can tighten up for longer passing shots or open things up for close flushes without buying anything extra. The receiver is lightweight aluminum, and the black synthetic furniture shrugs off weather and scratches that would make a wood stock owner wince.
Why This RIA Pump Gun Makes Sense
The forend deserves a mention too. It is shaped to fill the hand comfortably and keeps the pump stroke smooth, which matters when you are teaching someone new or running fast follow ups. A crossbolt safety sits right where pump gun users expect it, and a rubber recoil pad takes the edge off the already mild 20 gauge push. Between the soft recoil, the adjustable fit, and the versatile 26 inch barrel, this is a natural pick for a first shotgun, a loaner for the duck blind, or a do-it-all field gun that gets passed around the family. Rock Island backs it with a limited lifetime warranty, which is welcome peace of mind at this level.

Frequently Asked Questions
How does the adjustable stock on the All Generations shotgun work?
The buttstock uses a spacer system, so you add or remove spacers to lengthen or shorten the length of pull. There is also an adjustable cheek rest that raises or lowers to line your eye up with the rib. Between the two, you can fit the gun to a smaller framed or younger person, then build it back up as they grow or hand it to an adult.
Is the Rock Island All Generations 20 gauge a good first shotgun for a young hunter?
It is one of the better options out there for exactly that reason. The 20 gauge recoils noticeably less than a 12, the rubber recoil pad softens it further, and the spacer stock means the gun can shrink to fit a young person instead of forcing them to stretch. As they grow, you add spacers back rather than buying a new gun.
What can I hunt with the 26 inch barrel and the included chokes?
Quite a bit. With full, modified, and improved cylinder tubes plus a 3 inch chamber, this setup covers doves, pheasant, rabbits, squirrels, clay targets, and even ducks with the right nontoxic loads. The 26 inch vent rib barrel swings smoothly and points naturally on moving targets.
Does the All Generations 20 gauge shoot 2 3/4 inch and 3 inch shells?
Yes, the 3 inch chamber handles both 2 3/4 inch and 3 inch 20 gauge shotshells. That lets you run light and affordable target loads for practice, then step up to heavier hunting loads when the season opens. Capacity is 5+1 with standard shells.
