Add an extra 6 rounds capacity to your GSG Firefly .22LR magazine with this precision basepad and follower kit from Taylor Tactical Supply.

The kit includes the TTS +4 follower and extended aluminium baseplate.

  • Converts 10 round factory magazines into 16 round magazines
  • Suitable for LBP pistols
  • More durable than plastic base pads
  • Easier to grip for mag changes
  • Includes correct allen key for fitting

The follower replaces the standard follower and thumb assist, allowing room for an extra 4 round of .22LR.

This means the thumb assist operated last round lockback will not operate, instead the follower is designed to rise and block the slide going forward. Please note that this will release the slide when removing the magazine unless the slide lock is manually engaged.

For best results TTS recommend reversing the direction of the magazine spring so the top of the spring points to the rear.

Fits magazines for both the GSG Firefly and Sig Sauer Mosquito.
