Leupold 1 PC BASE MAR 336R Review

The Leupold 1 PC BASE MAR 336R Made a Bold First Impression

As an outdoor and tactical gear specialist with over a decade of experience, I’ve seen my share of scope mounting solutions. The market is flooded with options, from the incredibly complex to the almost ridiculously simple. When I first encountered the Leupold 1 PC BASE MAR 336R, I was immediately drawn to its apparent simplicity and the reputation of Leupold for reliability.

I needed a dependable, low-profile base for a new AR build I was putting together for a dedicated varmint rifle. I was looking for something that wouldn’t add unnecessary weight or bulk but would still provide a rock-solid platform for mounting my optic. I considered a few different options, including some two-piece bases and even a couple of cantilever mounts. I ultimately chose the Leupold 1 PC BASE MAR 336R due to its streamlined design and the promise of a secure, repeatable zero.

The Leupold 1 PC BASE MAR 336R comes in a simple, no-frills package. Upon opening it, I was immediately struck by its solid feel. The base is machined from steel and features a matte black finish. It inspires confidence in its durability. Compared to some of the lighter aluminum options I’ve used, this felt like it meant business. My first impression was one of quiet competence – this is a tool built to perform reliably.

Real-World Testing: Putting Leupold 1 PC BASE MAR 336R to the Test

First Use Experience

My initial testing took place at my local shooting range, primarily focused on zeroing the rifle and ensuring the optic held zero through a couple hundred rounds. I mounted a Leupold VX-3i 4.5-14x40mm scope on the base using Leupold PRW2 rings. The installation was straightforward, and the base aligned perfectly with the receiver.

During that range session, the weather was sunny and relatively mild. I experienced no issues with the base shifting or loosening, even with the consistent recoil of .223 rounds. The scope held zero perfectly throughout the entire session. It was a smooth, uneventful, and ultimately successful first outing.

Extended Use & Reliability

After several months of regular use, including multiple range trips and even a coyote hunting expedition, the Leupold 1 PC BASE MAR 336R has continued to perform flawlessly. There are no signs of wear or corrosion on the base despite exposure to varying weather conditions, including some light rain and snow. Cleaning is also simple; a quick wipe down with a lightly oiled cloth keeps it looking and functioning like new.

Compared to some cheaper bases I’ve used in the past that required constant retightening, the Leupold 1 PC BASE MAR 336R offers a significant improvement in reliability. It simply stays put and does its job, allowing me to focus on shooting.

Breaking Down the Features of Leupold 1 PC BASE MAR 336R

Specifications

• Material: Machined Steel – Provides superior strength and durability compared to aluminum alternatives.
• Finish: Matte Black – Reduces glare and provides a non-reflective surface, crucial for tactical applications.
• Mount Type: Weaver-style – Offers wide compatibility with a variety of scope rings.
• Compatibility: AR-15/M16 platforms – Specifically designed for a secure fit on these popular rifles.
• Profile: Low – Maintains a sleek, unobtrusive profile that minimizes bulk.

These specifications are crucial because they dictate the overall performance and reliability of the base. The steel construction guarantees it can withstand the recoil and stresses of repeated firing. The matte finish prevents reflections that could compromise a shooter’s position.

Performance & Functionality

The primary function of the Leupold 1 PC BASE MAR 336R is to provide a stable and secure platform for mounting a scope on an AR-15/M16 rifle. It performs this function exceptionally well. Accuracy is maintained because the base prevents any unwanted movement or flex. The only real “weakness” is that it isn’t compatible with picatinny rails directly, requiring weaver-style rings (though adapters exist).

It definitely meets and exceeds my expectations. This is not a flashy product, but it’s a reliable one.

Design & Ergonomics

The design is simple and functional. The low profile keeps the scope close to the bore, which can improve accuracy. The weight is noticeable compared to aluminum options but provides added stability. It is designed to fit the AR platform perfectly with proper screw spacing.

The Leupold 1 PC BASE MAR 336R is not particularly ergonomic in the traditional sense; it’s a base, not a grip. However, its low-profile design contributes to the overall ergonomics of the rifle by minimizing bulk and weight.

Durability & Maintenance

Given its steel construction and simple design, the Leupold 1 PC BASE MAR 336R is expected to last for many years with proper care. Regular cleaning with a lightly oiled cloth is all that’s required to maintain its condition. Repair is unlikely to be necessary; however, if a screw were to strip, it can easily be replaced.

The robust construction of the Leupold 1 PC BASE MAR 336R inspires confidence in its longevity, making it a worthwhile investment for serious shooters.

Accessories and Customization Options

The Leupold 1 PC BASE MAR 336R is compatible with any Weaver-style scope rings. While it doesn’t directly offer much in terms of customization, the choice of rings opens up a world of possibilities. This includes different heights, materials, and even quick-detach options.

While Leupold doesn’t offer specific accessories for the base itself, the broad compatibility with Weaver-style rings makes it incredibly versatile.

The Leupold 1 PC BASE MAR 336R is perfect for AR-15/M16 owners who prioritize reliability and stability in their scope mounting solution.

Those who prefer lighter aluminum mounts or require direct compatibility with Picatinny rails should skip this product. If you have an optic with picatinny style connection points, this is not for you without additional adapters. A must-have accessory is a quality set of Weaver-style scope rings.
