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.
