Here’s the critical truth: Here’s why, and how to actually do it. The Problem: The “Guts” vs. The Shell The Mossberg 715T is not an original design. It is, in essence, the Mossberg 702 Plinkster (a cheap, reliable, traditional-looking .22 rifle) stuffed inside a proprietary, two-piece polymer tactical shell. This is crucial because the serial number is not on the external shell you see and handle.

If you’re hoping to discover that your 715T is a rare, collectible variant with a special history, temper that hope. These were mass-produced budget plinkers. The lookup will likely confirm it was made between 2011 and 2016, and the most valuable piece of information you’ll receive is whether it needs a safety recall repair.

So, grab your screwdriver, pop open that shell, and call Mossberg. The answer is waiting—just not where you expect to find it.

The Mossberg 715T holds a strange, often controversial, place in the world of semi-automatic rimfire rifles. Introduced in the early 2010s, it was designed to capture the aesthetic of a tactical AR-15 platform while being an affordable, lightweight, magazine-fed .22 Long Rifle plinker. For many new shooters, it was a first step into the world of “black rifles.” For seasoned gun owners, it was often a puzzling curiosity—a plastic shell wrapped around a very different, much older action.
