86%PD | Tanfoglio Slide Optic Milling Current Turnaround Time: 3–6 weeksService Type: Milling Service only (Customer Provides Slide and Optic)   Service Details Our Tanfoglio Optic Milling Service includes: CNC-machined optic pocket in your supplied Tanfoglio slide. Rear sight dovetail removal and deck height reduction for a flat, clean install. Low sight picture for easier transition from iron sights. (This resolves the common issue with dovetail-mounted optics sitting too high.) Recoil bosses included for added rigidity and reduced stress on mounting screws. Modified CO Firing Pin Block available Option for purchase (see Additional Fees). Note: The factory FPB will no longer function due to the lowered deck height.   Important Notes Optic Manufacturer Tolerances: Patriot Defense has no control over optic manufacturers’ quality standards or elevation adjustments. Some setups may require a shim to achieve zero. This is common across platforms due to factors like bullet power factor, zero distance, optic design, and elevation range. → If you are not willing to potentially use a shim, we recommend using a rear sight mount instead. Precision Fit Guarantee: We guarantee a CNC precision fit between your optic and your slide if the optic is sent with your slide. If you do not send your optic, we will test fit using a “shop optic” on hand. Due to manufacturer tolerances, this may cause your optic not to fit correctly. If further machining is required, you will be responsible for return shipping.  Service Scope: This service does not include refinishing or the optic itself. Optional refinishing is available (see Additional Fees). USPSA Compliance: A modified Firing Pin Block is required to remain compliant with USPSA Carry Optics rules. Slide Preparation: All slides must have the rear sight removed before shipment
