Did not like a scope on my 12 gauge Thompson Center Encore shotgun and wanted a quality peep sight. This worked great on the weaver base. I did add a higher front sight and use the 0.125 aperture with a green fiber front.

fitted the Weaver mount peep sight to one model 99, will be ordering a second one for my 2nd model 99. Works very well even with me wearing bifocals

Great sight for bolt action shotguns where scopes are not an option. Have them on my model 212 X-Card shotguns.Very solid well made.

Needed a backup sight for Marlin 336 from 1955 with a Weaver base. It mates perfectly with the base and factory front sight. WEll made and easy to use. Great for the Deer Woods of Maine

Put this sight on a CVA Accura MR-X. Matched it with Williams western precision fiber optic front sight. Worked fantastic! Swap between peep and scope quickly.
