The Thompson Center “Ace in the Hole” Scope Rail offers unquestionable advantages and improvements over open sights. Made specifically for use on Thompson Center Muzzleloader Rifles, this receiver mounted, metal aperture sight is optically superior to open sights in accuracy. The closer the aperture is to your eye, the faster you acquire your shot, obscuring much less of your target and the surrounding area. Plus this sight allows accurate, repeatable, wind and elevation adjustments.

Williams® “Ace in the Hole” Rail Sight™ provides the perfect solution for mounting optics and retaining iron sights. Machined to standard 1913 picatinny rail specifications, the rail features cross slots for versatile mounting options, while at the same time, if something happens to your primary sighting option, you have an “Ace in the Hole” backup aperture sight. Ideal for scopes, red dot sights and tactical optics, this 3/8 x .093 aperture peep sight accepts the Williams™ ghost ring aperture as well.

Sight your rifle in faster no matter what the configuration. Remove a huge amount of aiming error, and improve the focus of your sight by increasing your sight radius, plus eliminate rear light reflection. With Thompson Center® “Ace in the Hole”™ picatinny rail sight, a longer sight radius with faster target acquisition equals undoubtedly more accurate shooting. Model 71009 fits T/C Prohunter, Encore, Omega, Endeavor, Triumph, and Impact Models.

***Williams® Sights are made of durable CNC machined metal.

Works Well

Mounted it on my 15" 357 Remington MAXimum MGM/Bellm pistol barrel. Allows a much wider range of scope positions than the traditional available mounts.

Wish it was made of steel to prevent flexing. With it securely mounted as designed, you can lift on the front edge of the mount and lift it off the barrel about 1/16". Need to drill and tap an additional barrel mounting screw to lock it down.

Needed to Shim

I bought two of these to give me options of sights on my Encore pistols. Using high mounts the peep sight clashes with the bottom of the scopes no mater what position it is placed. Removed the peep sight, mounted Bushnell Trophy XLT Handgun scopes and could not get the elevations to go up high enough to zero out at 100 yards!!!

I attempted to shim the scope with 0.003" shim material which failed to help. The machining must not run parallel with the bore. You may need a scope that has a greater adjustment range of 70" of elevation @ 100 yards (the spec on these scopes).
