Product Description


Looking for rock solid stability and dead-on accuracy in a fixed sight? Troy Industries Di-Optic Aperture (DOA) fixed sights get the job done with an advanced design, superior sighting ability and battle-ready toughness.. This permanent, rail-mounted alternative to a standard A2 sight allows limitless mounting options on all-length rails with a serrated ramp to eliminate glare. Provides a continuous zero, unflinching durability and peace of mind. These sights provide lightning fast target acquisition and are manufactured to exceed military specs. The optically engineered Di-optic apertures center your eyes instantly and effortlessly providing a clearer target picture than with round apertures. The sights feature two settings, one for up to 300 meters and a second for up to 550 meters. This versatility makes the DOA ideal for military, law enforcement and home defense applications. These advanced sights have been extensively field-tested and, like all Troy Industries products, are Battle Ready. Count on it.

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.
