Product Description


The TA648MGO-M2 6x48 ACOG is a Machine Gun Optic (MGO) designed specifically for the .50 BMG M2 weapon system. The MGO provides the shooter enhanced target identification and increased hit probability out to 2000 meters utilizing the Bullet Drop Compensator. With a built-in 1913 Picatinny rail on top, the MGO allows the end user to incorporate the Trijicon 1x42 Reflex (RX30/RX34) sight for convoy operations and/or close combat situations or any other target designators.

The TA648MGO-M2 incorporates dual-illumination technology using a combination of fiber optics and self-luminous tritium. This allows the close in reflexive fire aiming point to be illuminated without the use of batteries. The tritium illuminates the aiming point in total darkness, and the fiber-optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness.

 Optic Features:
  •   Fiber Optic Illumination Adjuster
  •   Integrated M1913 Rail
  •   100m Zero and 500m Zero Zeroing Instructions Laser Etched on Left and Right Side of Optic
  •   GDI Dual Auto-Locking Quick Detach (ALQD™) Levers
  •   Anti-Reflection Device & Protective Flip Caps
 Reticle Features:
  •   Dual Illuminated Green Dot Aiming Point for Close-in, Reflexive Fire
  •   BDC Designed with the .50 cal. Ammunition to Incorporate Spin Drift of the Round at Extended Distances
  •   Horizontal Target Reference System (50 Mils)
  •   Ranging Reticle from 100m (as shown in reticle image) to 2000m

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.
