Product Description


Grand Slam riflescopes compare to the best of the best at the sporting goods counter, except for the price tag. You'll find the cost of a Grand Slam is extremely reasonable for all the advanced features packed into it. Fully multi-coated lenses reduce glare and give you edge-to-edge clarity. They're outstanding in low-light situations.

All Grand Slam scopes feature a fast-focus eyepiece adjustment ring, to let you adjust the scope perfectly to your eye. The "sure grip" power ring helps you find and adjust the variables, even with heavy hunting gloves on.

Finally, Grand Slam's solid, one-piece construction helps make them waterproof, fogproof, and shockproof, so they'll last for years to come. It's one of the most versatile scopes made. Long-range rifles can take full advantage of 10 power magnification. A 40mm objective lens helps you see better at daybreak and at dusk.

Firearms Policy

How to Buy a Firearm or Ammunition

Federal firearms laws prevent the sale of a weapon from Red Dot Arms, LLC. directly to an individual in another state (we are located in Illinois). We must ship your firearm directly to an FFL Dealer near you. The steps to follow are:

  1. Order your firearm online using our secure shopping cart. If you know the FFL dealer you are going to use at time of order placement (not a requirement) enter his name and address into the 'Ship To' field.
  2. Find an FFL dealer near you that will accept the transfer of the firearm for you. Most sporting goods stores and pawn shops will provide this service for a small fee. Also, gun clubs, shooting ranges, etc. may provide this service to you. If you don't know which FFL dealer to use in your area, put a comment in your order and we will help you locate one near you. We have access to a large list of dealers in the USA that will gladly handle a transfer for you. Most dealers charge around $25 for a transfer. You must confirm the transfer with your local FFL dealer in advance.
  3. Next, have the dealer send us a copy of his signed license if we don't already have it on file. To check whether a license is on file, contact us. Please Note: It is now legal for us to accept a faxed or e-mailed copy of your dealers license! 
  4. Make sure the dealer knows the firearm is coming from Red Dot Arms. If you used a dealer that we already have on file, call him to let him know that a gun for you is on the way.
  5. We will send you an email when the firearm ships, which will include a tracking number.
