Description
The name is not just marketing. Rock Island built the All Generations pump around a stock system with removable spacers and an adjustable cheek rest, so the same shotgun can fit a smaller framed new shooter one weekend and a full grown hunter the next. Pull a spacer or two to shorten the length of pull, raise the comb to get your eye lined up over the rib, and the gun points where you look. That kind of adjustability usually shows up on shotguns costing a lot more, and it makes this one of the easier 12 gauges to share around a family or hand to someone just getting started.
A 28 Inch Vent Rib Barrel That Earns Its Keep
The 28 inch smoothbore barrel wears a ventilated rib with a bead front sight, giving you a clean sighting plane for wingshooting and clays. The 3 inch chamber handles everything from light target loads up to heavier hunting shells, and the threaded muzzle accepts the included Full, Modified, and Improved Cylinder choke tubes. Screw in the Full for longer shots on pheasant or turkey, drop to IC for close flushing birds or skeet, and you have one gun covering a whole season of different work.
All Generations Pump Specs Worth Knowing
The receiver is machined aluminum, which keeps overall weight manageable at around 8.8 pounds while the black anodized finish and synthetic furniture shrug off weather and field dings. Capacity is 5+1, the safety is a simple crossbolt behind the trigger guard, and the ergonomically shaped forend gives you a solid grip for running the action fast. Overall length comes in just under 49 inches with the stock at full length.
Why the Rock Island All Gen Makes Sense
Pump shotguns stick around because they run on just about anything and keep working when conditions get ugly. This one adds real fit adjustability and a three choke set on top of that reliability, backed by Rock Island Armory's limited lifetime warranty. For a first shotgun, a loaner for the duck blind, or an all purpose field gun, it checks a lot of boxes without complicating anything.

Frequently Asked Questions
Can the Rock Island All Generations really be adjusted to fit different shooters?
Yes, and it is the standout feature of this shotgun. The stock uses removable spacers so you can shorten or lengthen the pull, and the cheek rest adjusts for comb height. That means a youth shooter, a smaller framed adult, and a taller hunter can all get a proper fit from the same gun with a few minutes of work.
What shells will the All Generations pump handle?
It has a 3 inch chamber, so it runs both 2 3/4 and 3 inch 12 gauge shells. That covers light target loads for clays, standard field loads for upland birds, and heavier 3 inch hunting loads. As with most pump guns, cycling is manual, so it is not picky about shell power levels.
Which choke tubes come with this shotgun and when should I use each one?
It ships with Full, Modified, and Improved Cylinder tubes. Full is your tightest pattern for longer range work like turkey or late season pheasant, Modified is a good middle ground for general field hunting, and Improved Cylinder opens up for close flushing birds, skeet, and shorter range shots.
Is the All Gen a good first shotgun for a new shooter?
It is a strong pick for exactly that. The adjustable stock lets you size it down while someone learns and grow it back out as they do, and the simple pump action with a crossbolt safety is easy to teach. The 28 inch vent rib barrel also swings nicely for clays, which is where most new shotgunners start.
