Weaver Top Mount Aluminum Base 46M Review

First Impressions of Weaver Top Mount Aluminum Base 46M

The Weaver Top Mount Aluminum Base 46M is a seemingly simple piece of hardware, but its importance in creating a stable and accurate shooting platform cannot be overstated. As someone who’s spent over a decade in the outdoor and tactical gear world, I’ve learned that even the smallest components can make a world of difference.

I sought out the Weaver Top Mount Aluminum Base 46M to mount a new optic on an older Winchester Model 70 that hadn’t seen much use in recent years. I needed a solid, reliable base that wouldn’t break the bank, and Weaver is a name I’ve always trusted for dependable mounting solutions.

Upon unboxing, the base felt surprisingly solid for its lightweight aluminum construction. The black finish was clean and consistent, and the included screws appeared to be of good quality. Compared to some of the cheaper, pot-metal bases I’ve encountered, the Weaver Top Mount Aluminum Base 46M definitely felt like a step up. I considered a steel base for ultimate durability, but the weight savings and corrosion resistance of aluminum were appealing for this particular rifle. My initial impression was positive; it seemed like a well-made, no-frills base that would do the job.


Real-World Testing: Putting Weaver Top Mount Aluminum Base 46M to the Test

First Use Experience

I tested the Weaver Top Mount Aluminum Base 46M at my local shooting range, mounting it on my Winchester Model 70 in preparation for deer season. Installation was straightforward, taking only a few minutes with a properly sized screwdriver. The base sat flush against the receiver, providing a solid and stable platform for my scope.

After zeroing my rifle, I put about 50 rounds downrange. The Weaver Top Mount Aluminum Base 46M held firm, showing no signs of loosening or shifting. Despite the moderate recoil of the .30-06 cartridge, the base provided a stable and repeatable platform for accurate shots. The weather was dry and sunny, providing optimal conditions for testing the setup, but I made sure to apply some CLP to the screws just in case.

Extended Use & Reliability

After several months of use, including a deer hunting trip and multiple range sessions, the Weaver Top Mount Aluminum Base 46M has proven to be a reliable and durable mounting solution. There are no signs of wear or tear on the base itself. The finish has held up well, resisting scratches and corrosion despite exposure to the elements.

Cleaning and maintenance are simple; a quick wipe down with a cloth is all that’s needed. I periodically check the screws to ensure they remain tight, but they haven’t required any adjustments. Compared to other bases I’ve used in the past that required frequent tightening or showed signs of rust, the Weaver Top Mount Aluminum Base 46M has been a standout performer. It has outperformed my expectations for a base in this price range.
