The Rock Island Armory TK113 is a straightforward, reliable pump-action shotgun built for hunters and sport shooters who value simplicity and dependable function. This 12-gauge shotgun features a traditional pump mechanism, a 20-inch barrel, and a 3-inch chamber, making it a versatile choice for upland hunting, clay sports, and home defense. Rock Island Armory has built a solid reputation for delivering no-frills shotguns that work, and the TK113 carries that tradition forward—you get proven mechanics without paying for unnecessary features or excessive weight.
The 20-inch barrel strikes a practical balance: short enough for quick handling in tight cover or tight quarters, yet long enough to pattern shot effectively at typical hunting and defensive distances. The 3-inch chamber accepts both 2¾-inch and 3-inch 12-gauge shells, giving you flexibility to load what the job calls for. The pump action is intuitive, fast to operate, and easy to maintain in the field—no learning curve if you've run a shotgun before, and straightforward enough for newcomers to pick up quickly.
This is a shotgun that does its job without drama. Whether you're after upland birds, running clays, or keeping a reliable defense tool on hand, the TK113 delivers the core functionality that matters: smooth cycling, tight lockup, and the kind of durability that keeps working year after year with reasonable care.

Frequently Asked Questions
What shotgun shells does the TK113 accept?
The 3-inch chamber accepts both standard 2¾-inch and 3-inch 12-gauge shells, so you have flexibility in ammunition choice depending on your needs.
Is the Rock Island TK113 suitable for hunting?
Yes. The 20-inch barrel and pump action make it a practical choice for upland hunting and other field applications where a shotgun is useful.
How does a pump-action shotgun work?
A pump (or slide-action) shotgun cycles by manually moving the foregrip backward and forward with each shot. This ejects the spent shell and chambers a fresh round, giving you control over your rate of fire and making the action straightforward to operate and maintain.
