Utg super slim 20 picatinny mount. - Leapers UTG Super Slim 20 MOA Elevated Picatinny Mount, 13 Slot

Main reason for buying this is to provide metal reinforcement for plastic Picatinny rail molded into the Winchester Wildcat .22LR semi-auto rifle plastic receiver.

Main problem is no instruction were provided in the package. You have to contact the manufacturer for this.

Design seems good. You can see the plastic rear sight through the rectangular space in the UTG rail. Rectangular reinforcements in the rail lock into plastic Picatinny slots to prevent movement.

Best not to overtighten screws to prevent distorting plastic Picatinny rail. Use blue loctite on screws. Tighten just enough to stop any movement of aluminum rail if a telescopic sight is mounted. Stick with lighter weight and compact design scopes. Good idea is to spray plastic rail with Armor-All or similar plastic protectant. Let it soak in for 24 hrs, then wipe dry. Before installing UTG rail. Gives plastic extra protection from exposure to sunlight and other outdoor conditions. Keeps UTG rail from coming loose unexpectedly.

UTG rail is not bad for the price.
