Do you want a project that can stand the test of time? Do you want something with versatility for all those Mac-11 upper kits your wife told you not to buy? Well boy do I have the project for you.

The SaberToothMac-9 is a first in class build that will fit the big three when it comes to Mac-11 kits. Vmac, MAFco., MPA all have been tested and fit on the STM-9 so whether you like a side charging handle, top charging handle or non-reciprocating charging handle of the MPA then this is the way to go.

3D printer friendly, the STM-9 was designed from the ground up to print upright with minimal supports in mind. If you loved the Mac-Daddy then you'll be glad to hear even its stock/brace attachments and the aluminum feed ramp can be modified to fit the STM-9.

Extensively tested with over 1000+ rounds the STM-9 is as solid as it gets. Utilizing an MP90 style forward grip that is part of the printed frame and also acts as a forward magazine storage for easy reload access. It was a labor of love so I give thanks to the amazing rocketchat members who aided in the beta testing with me so I can finally present to the world the SaberToothMac-9.
