Part 9: Frequently Asked Questions (FAQ)

Q: Is the Bushnell 3-9x40eg rated for a magnum rifle (e.g., .300 Win Mag)? A: Yes, provided you maintain the 3.5 inches of eye relief. However, the "EG" is considered a budget-to-mid scope. On light magnums, repeated recoil can shift internal lenses faster than on a .308 or .30-06.

Q: I lost the flip-up lens caps. What size fits? A: The eyepiece is roughly 1.5 inches (38mm). The objective (40mm) takes a 40mm cap. Buy "Butler Creek" size 09 for the eyepiece and size 16 for the objective. bushnell 3-9x40eg manual

Q: The manual says "Fogproof." My scope fogged up. Why? A: Fogproof requires the seals to be intact. If the scope was dropped, or if it is older than 15 years, the O-rings may have dried out.

Q: Can I use this scope on a .22 LR? A: Absolutely. The 3-9x40eg excels on a rimfire for small game. The parallax is fixed at 100 yards, which is suboptimal for 25-yard .22 shots, but for hunting squirrels at 50+ yards, it works fine. Proper ring bases for your specific rifle (Remington

Step 1: The Battery

The "EG" in your scope won't work without power.

  • The Battery Type: Most Bushnell EG models use a CR2032 lithium coin battery.
  • Installation: Unscrew the cap on the top/side of the eyepiece. Insert the battery with the "+" side facing up.
  • The Test: Tighten the cap. There is usually a rotating ring on the battery housing. Turn it to "Red" or "Green." You should see the crosshair light up.
    • Pro Tip: Don't store the scope with the illumination on "Red" or "Green." Rotate it to the "Off" position or the white dot to save battery life.
