New MBX competition follower & spring sets need to be loaded 4-6 times to capacity preventing the follower popping out when new, insuring that the spring is set and the follower sits down in tube when new, this avoids any slide contact and damage to spring and follower voiding warranty as the competition follower is NOT held down by the slide stop and has minimal surface area, the competition follower is designed once spring is set to sit 1/4-3/8 below top of feed lips thus avoiding damaging slide contact with follower once the magazine is empty.
Combine the 17 RD Mag with the MAGPUL AMAG 17 rd Mag and GRAYGUN +5 Brass Mag Extension or GRAYGUNS +5 Aluminum Mag Extension to get 24+1
