Palma Dovetail Mount

This new product will allow a shooter to use the Scott Riles Palma upper assemblies with 18, 22, and 30mm accessory threads, on their domestic and European style smallbore/fullbore target rifles. This new mounting method will allow an option to the shooter to install his sight system on a tapered or larger than 0.850 diameter barrel, the barrel does not need to be turned to a specific cylindrical diameter.

This mount will accept the 18, 22 or 30mm Scott Riles Palma uppers same as the standard barrel base with no change in windage-zeros. The 30mm upper will give you a higher head position because of the nature of the design, roughly 0.210 of an inch.


The mount is designed to work with the 0.860 hole spacing dovetail base.

The Palma Dovetail Mount can be installed on a barrel with a diameter up to and including 1.000 inches. A precision standard scope base, 0.175 inches high by 1.30 inches long with a hole spacing of 0.860 inches is shipped with each unit. Two 6-48 screws are furnished with each unit to insure a proper fit.


The unit will mount on the top or bottom of a barrel, or on the top or bottom of a bloop tube. The base has an elevation scale engraved on both fore and aft surfaces to accommodate the top/bottom placements. The scales are an arbitray number for reference only.

These mounts are made from billet grade aircraft aluminum 7075-T651 and black anodized for durability. The same attention to accuracy and detail is taken in the manufacturing of the accessories as is taken in the manufacturing of the front sights.


The Palma Dovetail Mount comes with it's own unique retaining bolt for the upper, it is a different length than furnished with the basic Palma sights and must be used to secure the vertical pieces to the mount. You must verify clearance between the end of the bolt and the barrel during initial installation to prevent bolt contact with the barrel.

These units can also be used on Highpower and Fullbore rifles with larger than 0.850 diameter barrels by just adding the dovetail base to the barrel. Maxium diameter of the barrel is 1.000 inches. The barrel does not need to be turned to a cylindrical diameter for a proper mounting, just drill and tap two 6-48 holes on a 0.860 hole spacing, mount the base and you are in business.



All aluminum sight hardware and accessory items, except for the 30 mm lenses and
commercial bolts and washers,are designed and fabricated by Scott Riles. No exceptions
