WEAVER BASE PIVOT MOUNT 2PC 148* Review

The WEAVER BASE PIVOT MOUNT 2PC 148* Made a Bold First Impression

The WEAVER BASE PIVOT MOUNT 2PC 148* – even the name sounds utilitarian. These mounts promise a simple, affordable solution for attaching optics to firearms. The Weaver name carries weight in the optics mounting world, so I was eager to see if these budget-friendly pivot mounts lived up to the reputation.

My need arose from a recent project rifle, an old .22 I’m restoring for my son. I wanted to give him the option of using a scope without permanently altering the classic lines of the rifle. I wanted a solution that was robust enough to handle light recoil, easy to install, and wouldn’t break the bank, which ruled out many of the more elaborate QD (Quick Detach) systems.

Unboxing the WEAVER BASE PIVOT MOUNT 2PC 148*, I was immediately struck by their simplicity. They are small, steel, and finished in a no-nonsense blue. The machining looked clean, and the parts felt solid, though noticeably lightweight.

I considered similar low-profile options from Leupold and Redfield, but their offerings were double or triple the price. The WEAVER BASE PIVOT MOUNT 2PC 148* offered the best value proposition on paper. My first impression was cautiously optimistic; they seemed like a practical, if not particularly flashy, solution.

Real-World Testing: Putting WEAVER BASE PIVOT MOUNT 2PC 148* to the Test

First Use Experience

My initial test took place at my local shooting range, mounting a vintage Weaver scope on the aforementioned .22 rifle. Installation was straightforward, requiring only a few minutes and basic tools. The bases attached securely to the pre-existing dovetail on the rifle’s receiver.

The pivot mechanism operated smoothly, allowing the scope to be easily swung to the side for iron sight use. Initial zeroing was relatively painless, although the pivot action introduced a slight shift in point of impact when returning the scope to its shooting position. In dry conditions, the mounts performed adequately.

Extended Use & Reliability

After several weeks of use, the WEAVER BASE PIVOT MOUNT 2PC 148* proved generally reliable, but not without caveats. The blue finish began to show wear marks where the scope rings attached. More concerningly, after repeated pivoting, the mounting screws required occasional tightening to maintain a stable zero.

Cleaning was simple, requiring only a wipe-down with a lightly oiled cloth. Compared to more robust, fixed mounting solutions, these pivot mounts definitely require more frequent maintenance. While they offered a flexible solution for switching between optics and iron sights, their long-term stability wasn’t on par with dedicated scope bases.

Breaking Down the Features of WEAVER BASE PIVOT MOUNT 2PC 148*

Specifications

• The WEAVER BASE PIVOT MOUNT 2PC 148* consists of two individual bases designed to attach to a firearm’s receiver. These bases are typically designed for dovetail mounting, meaning they slide onto a grooved rail commonly found on rimfire rifles.
• The bases are constructed from blued steel, which provides decent strength and corrosion resistance at a lower cost. The “148” likely refers to a specific dimension or fitting code within Weaver’s product line.
• The pivot feature allows the scope to be rotated to the side, typically to allow for the use of iron sights. This is a useful feature for hunting situations where a quick transition between magnified optics and open sights might be necessary.
• These mounts are designed for use with standard Weaver-style scope rings. This provides a wide range of compatibility with different scopes and ring heights.

These specifications matter because they directly impact the mount’s suitability for various applications. The steel construction offers acceptable durability for light recoil firearms, while the pivot feature adds versatility.

Performance & Functionality

The WEAVER BASE PIVOT MOUNT 2PC 148* performs its core function – attaching a scope and allowing it to pivot – adequately. Accuracy is acceptable for casual shooting, but the shift in zero after pivoting limits its precision applications. For a .22 plinker or a close-range hunting rifle, the performance is serviceable.

The main strength is the convenience of switching between optics and iron sights without removing the scope. The primary weakness is the slight, but noticeable, shift in zero and the need for occasional tightening. They meet expectations for a budget-friendly solution but don’t exceed them in terms of precision or long-term stability.

Design & Ergonomics

The design is simple and functional, with no unnecessary frills. The blued steel finish is understated and blends reasonably well with most firearms. The light weight is a plus, as it doesn’t add significant bulk to the rifle.

The pivot mechanism is relatively easy to use, although the detent (the mechanism that holds the scope in the up or down position) could be more positive. There’s a slight learning curve in understanding how the pivoting action affects zero, but it’s not overly complicated.

Durability & Maintenance

Given the price point, the durability is acceptable, but not exceptional. The blued finish is prone to scratching, and the steel construction is susceptible to rust if not properly maintained. Expect these mounts to last for several years with proper care and light use.

Maintenance involves occasional cleaning with a lightly oiled cloth and periodic tightening of the mounting screws. Repairing these mounts is generally not feasible; replacement is usually the more cost-effective option.

Accessories and Customization Options

The WEAVER BASE PIVOT MOUNT 2PC 148* doesn’t come with any additional accessories. Customization is primarily limited to selecting compatible Weaver-style scope rings of the appropriate height. Aftermarket detents or pivot tension adjustment mechanisms are not readily available.

The mounts are compatible with a wide range of Weaver-style scope rings from various brands. This allows users to tailor the scope mounting system to their specific optic and shooting preferences.

The value proposition is strong, given the incredibly low price point. It is important to have realistic expectations regarding their long-term stability and the potential for a shift in zero after pivoting.

The price is definitely justified, considering the functionality and ease of installation. For casual shooters and plinkers on a tight budget, these mounts are a reasonable option.
