The Forge 4.5-27x50 riflescope has the premium features and optical brawn the recreational and competitive shooter needs to win, or the hunter to fill the freezer.

This is our highest magnification riflescope in the Forge line with a massive range of 4.5-27x. We offer it with the option of a first or second focal plane, and reticle options with crosshair or holdover style reticles.

Forge features our turret-halting Revlimiter zero stop which takes only seconds to set, and guarantees you'll always get back to your zero fast. Next, we put our Throw Hammer power change lever on the magnification ring so you can power up-and-down with speed and precision. Turrets are tactile and fast, simply lift up to unlock, push down to lock. The side focus parallax goes down to 25 yards. The glass has astounding brightness, resolution and contrast thanks to our HDOS fully multicoated optics, and of course our exclusive EXO Barrier. Rainy weather's not a problem for Forge as it's IPX7 waterproof. Finally, we've got you covered with our full, transferable lifetime Ironclad Warranty.

  • Revlimiter Zero Stop – A true zero stop that can be set quickly in the field.
  • Side Focus Parallax – focus quickly and accurately down to 25 yards.
  • Throw Hammer – Our power change lever to zoom in and out fast.
  • Locking Turrets – large, exposed & locking turrets for fast & accurate dialing.
  • Exclusive EXO Barrier Protection - Bushnell's newest and best protective lens coating molecularly bonds to the glass, repelling water, oil, dust, debris and preventing scratches.
  • IPX7 Waterproof construction - O-ring sealed optics stay dry inside, when immersed in three feet of water for up to 30 minutes.
  • Ultra-wide Band Coating - Anti-reflection coating applied to both lenses and prisms, for the best possible light transmission.
  • Includes magnetic closing box, 2” sunshade, and scope caps.
