Weaver Grand Slam S36 Two Piece Top Mount Base Review

First Thoughts on the Weaver Grand Slam S36 Two Piece Top Mount Base

In the world of optics mounting, a solid foundation is paramount. The Weaver Grand Slam S36 Two Piece Top Mount Base promises just that: a secure and reliable platform for your scope. Manufactured by Weaver, these bases are designed for specific rifles, ensuring a precise fit. Their claim to fame is their robust steel construction and recoil-resistant design, critical for maintaining zero in demanding shooting scenarios.

My journey to the Weaver Grand Slam S36 Two Piece Top Mount Base started with a common problem: scope shift on my deer rifle. After years of dealing with inconsistent shots, I knew the issue wasn’t the scope itself, but the less-than-stellar aluminum bases that came standard with the rifle. I needed something more robust, something that could handle the recoil of my .30-06 without budging. That’s when I began searching for a steel option, and the Weaver name kept coming up in conversations with fellow hunters.

Upon unboxing the Weaver Grand Slam S36 Two Piece Top Mount Base, I was immediately impressed by the weight and feel of the steel. The bases had a solid, substantial feel, a stark contrast to the lightweight aluminum bases I was replacing. The machining was clean, and the included screws looked significantly more robust than the factory hardware. The finish was a matte black, which should minimize glare in the field.

I considered several other options, including Leupold’s STD bases and Warne’s Maxima bases. Ultimately, I chose the Weaver Grand Slam S36 Two Piece Top Mount Base for a few key reasons. First, the price was significantly lower than the alternatives, which was a welcome bonus. Second, the Weaver name has always been synonymous with quality and reliability in the optics world. Finally, the two-piece design allows for greater flexibility in scope placement compared to a one-piece base.

My initial impression was one of cautious optimism. I was excited to finally have a solid mounting solution for my scope. I was also hopeful that it would eliminate the scope shift issues I had been experiencing. The quality of the steel and the precision machining gave me confidence that these bases would perform as advertised.

Real-World Testing: Putting Weaver Grand Slam S36 Two Piece Top Mount Base to the Test

First Use Experience

My first opportunity to test the Weaver Grand Slam S36 Two Piece Top Mount Base came at the local shooting range. I installed the bases on my .30-06 deer rifle and mounted my trusted Leupold VX-3 scope. The installation process was straightforward, thanks to the precise fit of the bases and the included hardened screws. I carefully torqued the screws to the recommended specifications, ensuring a secure and even mount.

The range conditions were ideal: a clear, sunny day with minimal wind. I started by shooting a few groups at 100 yards to establish a baseline. The initial results were promising, with the groups noticeably tighter than before. I then proceeded to run through a series of drills, including rapid-fire sequences and shooting from different positions.

After about 50 rounds, I checked the scope mounting screws to ensure they hadn’t loosened. Everything was still rock solid. There were no signs of movement or shift. The bases performed flawlessly, providing a stable and reliable platform for my scope. This was a huge improvement over my previous experiences with the aluminum bases.

Extended Use & Reliability

After several months of use, including numerous trips to the range and a week-long deer hunting trip in the mountains, the Weaver Grand Slam S36 Two Piece Top Mount Base continues to perform flawlessly. There are no signs of wear and tear. The finish is still in excellent condition. There is no evidence of rust or corrosion.

The bases have held up exceptionally well to the recoil of my .30-06, maintaining zero consistently. I have subjected the rifle to some pretty harsh conditions, including rain, snow, and extreme temperatures. The Weaver Grand Slam S36 Two Piece Top Mount Base has proven to be incredibly durable and reliable in all of these scenarios.

Maintenance is simple. I wipe down the bases with a lightly oiled cloth after each shooting session to prevent rust and corrosion. I also periodically check the mounting screws to ensure they are still properly torqued.

Compared to my previous experiences with aluminum bases, the Weaver Grand Slam S36 Two Piece Top Mount Base is a night and day difference. The Weaver bases provide a far more stable and reliable platform for my scope. I have complete confidence that my scope will stay zeroed, regardless of the conditions. They have absolutely exceeded my expectations.
