EPeS Gas Route GBB pads for M9 WE/TM – 3pcs

The Gas Route pad for GBB magazine discharge seal is a highly desirable accessory. Insert the pad between the Gas Route discharge seal and the magazine body, lifting the seal higher on the nozzle and enhancing consistency and performance where the original seal may not fully engage (e.g., due to wear).

CAUTION: In some cases, the pad may be undesirable, installation recommended only when necessary, not preventively!
