The Firefield Barrage 2.5 - 10 x 40 Riflescope with Picatinny Mount is great for short- to mid-range shooting. Using fully multicoated lenses, this riflescope is scratch resistant and antireflective for improved image clarity, while the MIL-DOT reticle accounts for bullet drop compensation. The waterproof, shock-proof and fog-proof design allows for use in most weather conditions, and the 6061-T6 anodized aircraft-grade aluminum construction affords long-term use.
