First Thoughts on the Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front
The Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front is a crucial piece of hardware often overlooked, but absolutely vital for mounting optics on a rifle. Weaver is a name synonymous with reliable mounting solutions, and this particular base is designed for the Interarms Mark X front action, a platform known for its ruggedness and dependability. I’ll be diving into whether this inexpensive option lives up to the Weaver name and provides a secure and accurate foundation for your scope.
My journey to this specific base began after acquiring a used Interarms Mark X rifle without any mounting hardware. I needed a reliable and affordable solution to attach a scope for an upcoming deer season. My primary requirement was a stable base that wouldn’t shift under recoil, maintaining zero even in harsh conditions.
Upon receiving the Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front, my first impression was of its lightweight design. The aluminum construction felt solid enough, though noticeably lighter than steel alternatives I’ve used in the past. It seemed a bit too minimalist, raising a small concern about long-term durability.
Compared to a one-piece steel base I considered from Leupold, the Weaver base was significantly cheaper and lighter. A Picatinny rail adapter also crossed my mind, but I wanted a streamlined, low-profile setup. The price point of the Weaver base ultimately swayed my decision, with the intention to thoroughly test its performance.
Initially, I was cautiously optimistic. The simplicity of the design was appealing, but the lightweight aluminum raised questions about its ability to withstand the recoil of my .30-06. Only real-world testing would reveal the true value of the Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front.
Real-World Testing: Putting Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front to the Test
First Use Experience
My initial testing of the Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front took place at my local shooting range. I mounted a Leupold VX-3i 3.5-10×40 scope on the base and proceeded to zero the rifle at 100 yards. The weather was mild, with clear skies and a slight breeze.
The mounting process was straightforward, thanks to the Weaver system’s simplicity. However, I did notice that the screws provided were quite soft, requiring extra care to avoid stripping the heads. After getting everything tightened to the manufacturer’s specifications, the scope felt surprisingly secure.
After about 20 rounds, I checked the screws and found one of the front base screws had slightly loosened. I re-tightened it, using a touch of thread locker for good measure. Aside from that initial hiccup, the base performed admirably during that first range session.
Extended Use & Reliability
After several months of use, including multiple range trips and a week-long deer hunt in the Pennsylvania mountains, the Weaver Model #20A Detachable Top Mount 2-Piece Base, Fits Interarms Mark X Front has proven surprisingly reliable. The initial screw issue hasn’t recurred since applying thread locker. The base itself shows no signs of bending or warping despite the moderate recoil.
I did notice some minor cosmetic wear on the edges of the aluminum base, likely from handling in the field. Cleaning is simple, requiring just a wipe down with a lightly oiled cloth to prevent corrosion. So far, it seems to outperform my initial expectations, given its low cost.
Compared to my experience with more expensive steel bases, the Weaver base requires slightly more vigilance regarding screw tightness. However, the significant cost savings make it an acceptable trade-off for many applications. While I wouldn’t trust it on a magnum caliber rifle, it’s perfectly suitable for standard cartridges like the .30-06.
