Taran Tactical 4G Basepads

This Patented push pin design is indestructible and will not come off until you are ready to remove it. One Piece construction made from solid aluminum, will not break or come loose, which is essential in the heat of competition. This base pad allows the magazine to be disassembled in seconds with one hand and no tools. You don’t have to worry about losing small parts or specialty tools to disassemble it.

  • *4mm (4 the Gauge) is recommended for anyone doing mag tuning who has a USPSA mag gauge.
  •  -The 4mm is angled in the back and will fit the gauge while allowing one extra round over the 3mm. It’s the base pad that all the mag tuners have been waiting for to get that extra edge!

MBX "Ultra Max" Spring & Follower for Atlas / Bul / Springfield Prodigy / SV / Staccato 2011 Magazines

FOR:
STACCATO/STI FACTORY TUBES
SPRINGFIELD PRODIGY FACTORY TUBES
SVI/INFINITY FACTORY TUBES
CHECKMATE/ATLAS GUN WORKS FACTORY TUBES
BUL/ARMSCOR/PARA FACTORY TUBES

NOTE: Factory style tubes with the “NEW” MBX Spring and S Follower Set that extend to 141.25mm allows for our combination using non lock back competition S follower to hold 23rds +1 with room for slide to cycle and reload with 23rds in tube.

In order to achieve 23rds you may need the help of a loading device. I may take a little break-in time for the spring to set and sit correctly in the tube. Please be patient we have spend many hours developing the sets so we know the capacity with factory spec ammo.

Follower 3D Printed: Our Followers are made from a specific blend of material 2e have developed for this purpose and are 3D printed. If you are against the look or simply the ideal and feel this is not for you than please do not purchase. Remember the facts are MBX has been the most innovative company in the magazine business for Reliability, Performance, Capacity and part of that is Developing Innovative 3D follower Designs that simply can not be effectively molded.


IMPROVE YOUR MBX MAGAZINE WITH “MBX ‘ULTRA MAX’ SPRING & FOLLOWER SET

*Note This Product will not lock slide back on last round fired

    Awesome but PLEASE READ

    Posted by Phillip Colby on Jul 4th 2019

    Ben Stoeger did a great job with the order and it surprised me when they contacted me about a delay in the base pads and offered a different solution. I was impressed!!! I waited and when finally delivered the followers were popping out of the mag and jamming the gun. The only reason why I didn't give them 5-stars was due to the fact that I realize they are not going to calibrate them but at least send them out to where the followers don't protrude from the top of the magazine. I hope I can calibrate them so that doesn't happen but I am super impressed with Ben Stoeger Pro Shop sales staff and thanks for awesome customer service.
