Mount Up! Horizontal Instructions

Tools needed for all installations:

  • Stud Finder (or other method)
  • Electric Drill
  • Bubble Level
  • 3/16″ Drill Bit
  • 7/16″ Socket with Ratchet
  • 3/16″ Allen Key or Hex Driver
  • 5/32″ Allen Key or Hex Driver
  • Small Hammer or Mallet
  • 1/8″ Pin Punch (if available)
  • 5/64″ Allen Key or Hex Driver

Attention! 2018 and beyond mount up systems utilize a key-retaining, plunger style lock. Once your key is inserted and turned to unlock, the key will remain in the lock and can spin freely. The key can only be removed from the vertical position from which it was inserted.

*If the plunger is sticking out of the face of the lock, your bracket is unlocked!*

*To lock, simply push the plunger into the lock, and double check that the bracket is locked by attempting to depress the red button!*

Installation Instructions – Mount Up! Horizontal (500054)

  1. Unpack the contents of your package and remove the red clevis pin retaining sticker on the right-hand side of your bracket(s).  Break your bracket(s) down into three pieces for installation (item #’s 10, 13, and 14).
  2. Locate the wood stud where you want to mount your bracket.  Brackets can also be installed into block or concrete walls with appropriate anchors (not included).
  3. Mark either the top or bottom hole location of the mounting plate (#2) on the wall.
  4. Drill a 3/16″ pilot hole at this location, into the stud, AT LEAST 2-1/2″ DEEP into the stud.
  5. Screw the lag bolt (#3) with washer (#4) into the stud using a 7/16″ socket and ratchet.  Secure, but do not over-tighten.
  6. Place your bubble level against one of the flat sides of the mounting plate (item #2) and mark the location for the second hole.
  7. Repeat steps 4 and 5 to mount the plate on the wall.
  8. Cover the lag bolt heads with the black covers (#5).
  9. Cover the ends of the mounting plate with covers (#6)
  10. Choose the four “bumpers” (#’s 7-9) that you need for your firearm using the guide below.  Press them into the grooves on the inside of the rear block (#10), and the front block assembly (#13).
  11. Using a 3/16″ allen key or driver, mount the rear block (#10) to the mounting plate (#2) using the 1/4″-20 socket head cap screws (#11) and the t-nuts (#12). The block can be mounted on the left or right side of the plate, depending on preference.  BE SURE TO COVER THE LAG BOLT WITH THE BLOCK FOR SECURITY PURPOSES.
  12. Align the holes in the rear block (#10) and the front block assembly (#13) and insert the clevis pin (#14) to join the parts.  THE HOLE IN THE CLEVIS PIN MUST BE ALIGNED WITH THE HOLE IN THE REAR BLOCK.
  13. Use a small hammer or mallet to pin the clevis pin (#14) in place, using the 1/8″ spring pin (#15).  Use a pin punch (if available) or the second included spring pin (#15) to tap the spring pin slightly past flush.
  14. Screw the nylon thumb screw (#16) into place on the top of the rear block (#10).  The angle on your buffer tube will stop against this post, preventing any damage to your weapon or bracket while in use.
  15. Peel backing off handguard rest pad (#19) and apply it to the handguard rest (#18).
  16. Mount the handguard rest (#18) to the plate (#2) using the button head screw (#20) and t-nut (#12). IT IS HIGHLY RECOMMENDED THAT THE REST COVERS THE SECOND LAG BOLT FOR SECURITY PURPOSES, IF THE FIREARM CONFIGURATION ALLOWS.
  17. (FOR VERTICAL SYSTEMS ONLY) Screw the nylon tipped setscrew (#15) into the rear block (#9) on the side opposite of the red button, ON THE BOTTOMof the clamp assembly.  Use this setscrew to achieve perfect vertical alignment of your firearm when in the bracket (some firearms may hang crooked depending on setup.  Use this screw to counter act this effect).
  18. Unlock your bracket with the key.  Open the bracket by depressing the red button and place your firearm into the bracket.  Close the bracket and ensure that the red release button has engaged.  The bracket clamps on the buffer tube between the castle nut, and the angled portion of the tube.
