First Thoughts on the Top Mount Base Marlin 39A, 90 Black, Poly Bag
The Top Mount Base Marlin 39A, 90 Black, Poly Bag might seem like a small, unassuming piece of equipment, but for Marlin 39A owners, it’s a crucial component for unlocking the rifle’s full potential. It bridges the gap between a classic firearm and modern optics, allowing for improved accuracy and versatility. This review will dive deep into whether this simple aluminum base lives up to the needs of serious rimfire enthusiasts.
I needed a reliable and low-profile way to mount a scope on my vintage Marlin 39A, a rifle I inherited from my grandfather. The rifle’s inherent accuracy always impressed me, but my aging eyes struggled with the iron sights. Several scout scope mounts seemed overly bulky and expensive, and I wanted something that wouldn’t detract from the rifle’s classic lines. The Top Mount Base Marlin 39A, 90 Black, Poly Bag seemed like the perfect solution on paper.
Upon opening the simple poly bag packaging, I was immediately struck by the base’s lightweight feel. The black finish appeared even and consistent, though I noted it was a painted finish, not anodized. Build quality seemed decent for the price point, but I was keen to examine the fit and finish more closely during installation.
Compared to more elaborate, and frankly, more expensive, rail systems, this base prioritizes simplicity and affordability. I chose it over a cantilever mount from Weaver because I wanted the lowest possible profile and to avoid any unnecessary bulk. I also considered a dovetail-to-Weaver adapter, but the Top Mount Base Marlin 39A, 90 Black, Poly Bag appeared to offer a more secure and stable mounting platform.
My first impression was cautiously optimistic. The price was certainly right, but I was hoping for a more robust finish and perfectly machined edges. The true test would be how well it mounted to the rifle and whether it could withstand the recoil of countless .22 LR rounds.
Real-World Testing: Putting Top Mount Base Marlin 39A, 90 Black, Poly Bag to the Test
First Use Experience
My first test of the Top Mount Base Marlin 39A, 90 Black, Poly Bag occurred at my local shooting range. The installation was straightforward, requiring only a few minutes and some basic tools. I mounted a Leupold VX-Freedom 3-9×40 scope on the base and zeroed the rifle at 50 yards.
The base performed admirably during the initial sighting-in process. The scope remained securely mounted, and the rifle maintained its zero even after firing several hundred rounds. The weather was dry and sunny, so I didn’t encounter any challenging environmental conditions. The base didn’t require any getting used to, and the low profile made it feel natural when handling the rifle.
My main surprise was how well the simple screws that came with the mount held up. I had braced myself to need to replace them immediately with higher-quality fasteners. Overall, my initial use was surprisingly positive.
Extended Use & Reliability
After several months of regular use, the Top Mount Base Marlin 39A, 90 Black, Poly Bag has held up reasonably well. I’ve taken the rifle on several small game hunts and plinking sessions. I even carried it in a scabbard during a late-season deer hunt.
The finish has started to show some wear and tear, with a few minor scratches and chips appearing. The screws have remained tight, though I periodically check them to ensure they haven’t loosened. The base itself shows no signs of bending or warping, indicating that it is structurally sound. The rifle maintains its zero consistently, even after being bumped around in the field.
Compared to my experience with more expensive scope mounts on other rifles, this base performs adequately but falls slightly short in terms of durability. An anodized finish would undoubtedly offer better scratch resistance and overall longevity. However, considering the price, I’m pleased with the performance.
