First Thoughts on the Leupold 176397 BackCountry Base For Rifle Browning X-Bolt Picatinny Rail Mount For Long Action 20 MOA Matte Black Aluminum
The Leupold 176397 BackCountry Base For Rifle Browning X-Bolt Picatinny Rail Mount For Long Action 20 MOA Matte Black Aluminum – quite a mouthful, but a potentially critical piece of equipment for any serious long-range shooter using a Browning X-Bolt. A quality base is the foundation upon which accurate optics are built. Without a solid mounting system, even the best scope is useless. Leupold has a long-standing reputation for producing high-quality optics and mounting solutions. This BackCountry base aims to bring that reputation to the Browning X-Bolt platform.
My need for this base stemmed from a frustrating experience at a long-range shooting competition. I was struggling to dial in enough elevation on my scope to reach targets beyond 800 yards. I needed a solution to provide additional elevation without maxing out my scope’s internal adjustments, hence the desire for a 20 MOA base. This promised to shift my scope’s zero point, granting me much-needed upward travel for those distant shots.
Upon unboxing, the base felt solid. The matte black aluminum finish looked clean and professional. The machining appeared precise, with sharp, well-defined Picatinny slots. It felt significantly lighter than the steel base I was replacing, a welcome change for a rifle I already lug around the mountains.
Compared to other bases on the market, like those from Talley or Warne, I chose this Leupold offering specifically for the 20 MOA elevation. While others offered similar construction, the added elevation seemed like the best solution for my long-range aspirations. My initial excitement was tempered by the user feedback I saw online. Some people reported fitment issues, so my fingers were crossed that it would work on my rifle.
Real-World Testing: Putting Leupold 176397 BackCountry Base For Rifle Browning X-Bolt Picatinny Rail Mount For Long Action 20 MOA Matte Black Aluminum to the Test
First Use Experience
My first experience with the Leupold 176397 BackCountry Base involved mounting it on my Browning X-Bolt Long Action rifle and heading to the range. Installation was straightforward, using the factory action screws. However, the initial impression took a hit when the provided screws felt a bit soft. Torqueing to the manufacturer’s recommended specs resulted in one screw head slightly deforming. This immediately raised concerns about long-term durability.
Performance-wise, the 20 MOA elevation was immediately noticeable. I was able to zero my scope at 100 yards with a significant amount of upward travel remaining. This was exactly what I was looking for. The base itself seemed stable, with no noticeable shift in point of impact during the initial testing session.
Extended Use & Reliability
After several weeks and multiple range trips, my initial concerns about the screws proved valid. I noticed that the base was starting to loosen slightly. Upon closer inspection, the screws were showing more signs of wear. I replaced the Leupold screws with higher-quality aftermarket options made from hardened steel.
With the new screws, the base held zero much more reliably. It withstood the recoil of my .300 Win Mag without issue. There were no further signs of movement or loosening. The matte black finish has held up well, with minimal scratches or wear despite being exposed to various weather conditions.
Maintaining the base is simple. I wipe it down with a clean cloth after each range session to remove any dirt or debris. A light application of gun oil helps prevent corrosion. Despite the initial hiccup with the screws, the Leupold base ultimately performed as intended after the upgrade.
