Vortex Optics Viper PST Gen II
The Vortex Optics Viper PST Gen II 5-25x50 is built for precision and performance, catering to hunters and long-range shooters alike. With its 5-25x magnification, this scope is ideal for extended ranges, providing clarity and detail necessary for critical shots. The illuminated reticle, combined with its precision-glide erector system, offers smooth magnification adjustments, which proves invaluable when conditions demand quick and accurate changes. Engineered with tactical shooting in mind, the Viper PST Gen II features an exposed turret with RZR zero stop, allowing you to return to zero with ease. Add in its rugged construction, and you've got a scope designed to perform in tough environments while delivering high-end features that make the shot count.
Monstrum Alpha
The Alpha Series GA1424 FFP Rifle Scope by Monstrum Tactical is built for serious shooters looking for reliability without unnecessary features. With 1-4x magnification, this scope excels at close to mid-distance shooting, reaching out to 300 yards. It boasts a first focal plane MOA reticle that provides clear ranging information, making it easy to estimate distances and adjust for holdover. Constructed from tough aircraft-grade 6061 aluminum, it features a sealed, nitrogen-charged tube to keep out moisture and fog. The MIL-STD 8625 type III hard anodized finish ensures it can withstand rugged conditions. Plus, it comes with spring-loaded flip-up lens covers to keep your lenses protected. The scope also includes a two-year replacement warranty. However, it does not offer reticle illumination, locking turrets, a detachable honeycomb killflash, or scope rings.
