Sun Optics Shotgun Saddle Mounts are made from aircraft quality aluminum. They install back over the receiver on ribbed shotguns without mounting properties. See below for more detailed installation instructions.


  • Full length picatinny rail mounts to fit ribs up to 3/8” wide
  • Works with 12 or 20 GA vent ribbed shot guns
  • Alternative choice for ribbed shotguns without mounting properties
  • Mounts back over receiver
  • Installs using provided plates that fit through vent rib
  • Made from lightweight aircraft aluminum
  • Satin black finish



  1. Place the mount on the vent rib of the gun
  2. Move the mount forward or backward so that two of the notches line up with the vent rib and it is positioned for proper eye relief
  3. Place the recoil keys through and install the 6-32 x 1/4" flat head screws. DO NOT TIGHTEN!
  4. Slide the mount forward until the recoil key contacts rib support
  5. Center the mount on the rib by adjusting the four set screws on the sides of the mount
  6. Tighten the recoil key screws and tighten the adjusting screws
  7. The mount is now ready for scope installation. After firing check all screws and re-tighten if necessary


    Price Match

    We guarantee that we offer the best prices online.

    If you come across another online retailer that sells the same item from the above manufacturer at a lower price plus shipping cost within one month of purchase, please let us know, and we'll refund the original payment for the difference in price.

    For the guarantee to apply, the total order price of the item which includes shipping cost must be lower than what you paid us. For example, let's say you paid a total of $150 for an item on our site. If you see the same item advertised for $140 on another site but shipping cost is an additional $15, the guarantee DOES NOT apply since the total order price is $155.

    On the other hand, if the same item is $140 but the shipping cost is an additional $5, the guarantee DOES apply since the total order price is $145 which is lower than what you paid us. The refund amount would be $5 for the difference. Please note we don't factor sales tax into the total order price when considering the guarantee. 

    You can email us a link to the product on our website, as well as the link to that same product on our competitor's site within one month from your order date, to request for the partial refund. 

    There are a few limitations on our price guarantee:

    • Items must be purchased from our site before requesting the Price Match guarantee
    • Promotions such as rebates and buy one, get one free offers are not eligible
    • The item must be in stock on the competitors website
    • The competitor must only be an online store and not have a physical retail location
    • The lower price cannot be found on an auction or market site like eBay, Amazon, Overstock, Wayfair, Jet, etc.
    • The competitor must be an Authorized Dealer or Retailer of that product
    • The Guarantee includes the total price of the item, but does not include sales tax
