First Thoughts on the Weaver Grand Slam S61 Two Piece Top Mount Base
The Weaver Grand Slam S61 Two Piece Top Mount Base – the unsung hero connecting optic to firearm. It’s easy to overlook the importance of a solid base until you’re chasing your zero across the range, or worse, in a critical hunting situation. Weaver, a name synonymous with reliable mounting solutions, offers the S61 as part of their Grand Slam line. This base promises a custom fit and recoil resistance at a price point that won’t break the bank.
My current hunting rifle was experiencing some zero drift and I realized the factory base was the weak point. I needed a durable, reliable base that wouldn’t shift under recoil, providing a stable platform for my scope. Unboxing the Weaver Grand Slam S61 Two Piece Top Mount Base, the first thing I noticed was the clean machining and solid steel construction. They felt heftier and more substantial than the aluminum bases I had previously used.
Compared to a Leupold STD base and a set of Warne Maxima bases I’ve used in the past, the Weaver offered a similar level of robust construction at a lower cost. I chose the Weaver Grand Slam S61 Two Piece Top Mount Base because of Weaver’s reputation for quality, the specific fit for my rifle, and the promise of a recoil-resistant, steel platform. My initial impression was one of cautious optimism. Could these bases deliver the reliable performance I needed without the premium price tag?
Real-World Testing: Putting Weaver Grand Slam S61 Two Piece Top Mount Base to the Test
First Use Experience
I mounted the Weaver Grand Slam S61 Two Piece Top Mount Base on my Winchester Model 70 chambered in .30-06. The first outing was a trip to my local shooting range on a crisp autumn day. Installation was straightforward using the included screws, with each base aligning perfectly to the pre-drilled receiver holes.
The conditions were favorable, around 50 degrees Fahrenheit with a slight breeze. I fired approximately 60 rounds of varying grain weights to test the base’s ability to hold zero. I was pleasantly surprised by the ease of use and the stability provided by the Weaver Grand Slam S61 Two Piece Top Mount Base. There were no immediate signs of shifting or loosening after the initial range session.
Extended Use & Reliability
After several months of use, including a deer hunting season in the often-harsh conditions of the Pacific Northwest, the Weaver Grand Slam S61 Two Piece Top Mount Base has held up admirably. Exposure to rain, mud, and fluctuating temperatures didn’t seem to affect its performance. I’ve put approximately 200 rounds through the rifle since installing the base.
There are no visible signs of wear and tear beyond some minor scuffs from handling in the field. The Weaver Grand Slam S61 Two Piece Top Mount Base requires minimal maintenance. A quick wipe down with a lightly oiled cloth after each use is all it needs. This greatly outperformed the aluminum base it replaced. The confidence this provided in my equipment greatly improved my hunting experiences.
