This 3-position SEF selector is designed for the FRT-RD3 trigger pack in PTR MP5 clones, offering standard fire control markings. Drop-in installation requires no fitting for properly assembled lowers.
The 3-position SEF selector provides correct marking alignment for semi, full, and safe positions when paired with Rare Breed Triggers' FRT-RD3 pack in PTR-based MP5 clones. Machined from steel with positive detent engagement, this selector maintains the classic MP5 profile while accommodating the FRT system. No gunsmithing is required for installation on in-spec lowers – simply remove the existing selector and install this unit with the included detent spring. The selector’s lever length matches OEM specifications to prevent interference with aftermarket grips or stocks. Compatible only with PTR 9CT/9KT/32KT models using the FRT-RD3 trigger group. Ships direct with no FFL required.
