The Top Mount Base Mrln 36/336 MOSS 640, 63BS Silver, Poly Bag Made a Bold First Impression

Mounting optics on a rifle should be a straightforward affair, but sometimes the simplest tasks can become frustrating ordeals without the right equipment. The Top Mount Base Mrln 36/336 MOSS 640, 63BS Silver, Poly Bag, a product seemingly basic in its description, promised a solution to a very specific problem: securely mounting a scope on my Mossberg 640 rifle. This isn’t just any base; it’s designed to bridge the gap between a classic rifle and modern optics technology.

I needed a reliable mounting solution for a vintage Mossberg 640 I recently acquired. The rifle, a .22LR known for its accuracy, lacked any pre-drilled mounting points for modern scopes. After scouring online forums and consulting with fellow enthusiasts, the Top Mount Base Mrln 36/336 MOSS 640, 63BS Silver, Poly Bag kept surfacing as a recommended option.

Upon receiving the base, packaged simply in a poly bag, my initial impression was positive. The silver finish was clean and the base felt surprisingly solid for its size. It’s machined aluminum, giving it a light yet sturdy feel that inspired confidence.

Compared to universal scope rails, which often require significant modification and can be bulky, this base seemed purpose-built and low-profile. I also considered a gunsmithing job to drill and tap the receiver, but the Top Mount Base Mrln 36/336 MOSS 640, 63BS Silver, Poly Bag offered a non-permanent and less invasive alternative. The appeal was clear: simplicity, affordability (at just $8.99), and a tailored fit.

Initially, I was cautiously optimistic. The simplicity was appealing, but I wondered if a single, small base could truly provide a stable platform for an optic. I was eager to get to the range and see if it lived up to its promise.

First Use Experience

My first test of the Top Mount Base Mrln 36/336 MOSS 640, 63BS Silver, Poly Bag took place at my local shooting range.
