The UFG9

Intro

The UFG9 - A Brief History

Originally named the 3DFMG, I changed it because the Magpul FMG folded in half using a clamshell design. Since this model doesn't resemble the FMG closely enough, it needed a new name: Under Folding Glock 9 (UFG9).

The design resembles a briefcase, toolbox, or lunchbox, and is spring-loaded to assist in opening. It includes rails compatible with PY2A, FMDA, and P80 platforms.

Recommended Rails:

- Printyour2a.com (PY2A)

- Riptiderails.com (FMDA)

- JSD Supply

- Rook Tactical (for P80)

Note:

This design was beta tested and hosted by a design group who has requested to have their name not be associated with this release, out of respect for their wishes that has been done.

2. Join left and right releases with 2x M3-35 SHCS and nuts.

3. Place AR-15 Buffer Detent Spring in the Carry Handle Spring Detent, and pass both through the front hole with the spring facing forward.

4. Secure with the Carry Handle Spring Retainer and M3-12 SHCS and nut.
