The Minotaur Tactical Shotgun Rail #00001MTR will fit all Mossberg 500 an 590 shotguns and the New Remington 870's that are factory drilled and tapped. (Our rail #00001MTR rail will also fit any other shotgun that can be drilled and tapped by your local Gunsmith.)

Read all Instructions before installing Rail.

Installation is simple and does not require any specialized tools or gunsmithing experience.

Required Tools:

• Narrow flat head screwdriver.

• Allen Wrenches. (If you are using T-handle Allen wrench only finger tighten the Allen screws to avoid stripping)

• Blue Removable LocTite (optional).

• Gun oil or lube (optional).

Installation:

1. MAKE SURE SHOTGUN IS UNLOADED.

2. Using a small flat head screw driver, remove the factory crews from your shotgun's receiver.

3. Attach Minotaur Tactical Rail to your receiver with provided screws - Do not tighten at this time. (Note we have included three sets of screws - One set of four to install the barrel clamp  - One set for Remington 870  - One set for Mossberg 500/590 series).

4. To install the barrel clamp first apply a generous amount of oil or gun lube to the barrel area that the clamp will be installed.  Snap the clamp over the barrel or slip on from the end of the barrel. The lube helps to reduce the possibility of scratching your barrel).

5. Align barrel clamp with the four holes on the rail and loosely install provided screws.

6. Now you may hand tighten the receiver screws (If you plan to use removable LocTite now would be the time to remove the receiver screws one at a time and apply a drop of same before finger tightening with an Allen wrench. Do not over torque to avoid stripping them out.)

7. Once you have completed step 6 you may hand tighten the barrel clamp screws. The rail may require a small amount of hand torquing to align with the barrel clamp. (If you plan to use removable LocTite now would be the time to remove the receiver screws one at a time and apply a drop of same before finger tightening with an Allen wrench. Do not over torque to avoid stripping them out.)  

8. See easy as can be as long as you remembered  "Righty Tighty and Lefty Loosey"

9. Install your options and head for the Range.
