This is the mega pack of the WTF-9, a 9mm semi-automatic, partially 3D-printed and partially machined firearm. It is the evolution of its predecessor, the AP-9, featuring major changes such as an improved bolt design and the elimination of the buffer tube. The WTF-9 is a modular platform that comes with several accessories, such as multiple folding stocks and foregrips, and has a dedicated community continually designing more upgrades and accessories.
Special thanks to the following contributors:
Derwood - The original designer and tester of the AP9 and the WTF-9
Mussy - For the immense amount of work to make the WTF-9MV and the WTF-9 accessories a reality
Bob_the_Builderer - For his work on the technical drawings of the WTF-9 bolt and firing pin

Abide by all local/federal laws and regulations before building the WTF-9. You are liable for any damage or injury to

* What is the WTF-9?
The WTF-9 is a semi-automatic, partially 3D-printed and partially machined firearm. It is constructed using 3D printed
components, easily-obtainable hardware store fasteners, a DIY-style steel bolt, as well as a few firearm components
(Glock mag/barrel, AK-47 recoil spring, and AR-15 FCG).
It is the evolution of its predecessor, the AP-9, featuring major changes such as an improved bolt design and the elimination
of the buffertube. The WTF-9 is a modular platform that comes with several accessories, such as multiple folding stocks
and foregrips, and has a dedicated community continually designing more upgrades and accessories.
It comes in two variants, the WTF-9MV (Mussy Variant) and the WTF-9H (Hillbilly), both of which are compatible with
the variety of accessories currently available and those still in development.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* What are the differences between the WTF-9MV (Mussy Variant) and the WTF-9H (Hillbilly) versions?
The WTF-9H is compatible with shorter length barrels, such as Glock 26 barrels that will not fit the WTF-9MV model
properly, since it is designed to use Glock-17 length barrels and longer.
The WTF-9H is essentially a lighter version with fewer components, it includes a shorter barrel retainer while the
WTF-9MV has a longer barrel retainer that doubles as a handguard, while also housing the longer barrel and charging
handle found on the WTF-9MV.
The lower receivers are interchangeable between the WTF-9MV and the WTF-9H variants.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Can I use any other (non-Glock) barrels with the WTF-9 variants?
The community is currently working on making the WTF-9 variants compatible with electrochemically-machined barrels,
for regions of the world where Glock barrels may be difficult to obtain.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Can I use any other fire control groups?
The community is also currently working on making the WTF-9 variants compatible with airsoft style fire control groups,
but as of right now, the AR15 fire control group will be needed to build the WTF-9 variants.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Are there any customized parts available for the variants?
There is a community developed designs folder hosted on the WTF-9 keybase team, including several customized models
of the lower receivers.

WTF-9: Accessories
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Foregrips and stocks for the WTF-9 variants are designed by Mussy
* https://www.thingiverse.com/mussy/designs
The detachable rail version of the WTF-9MV handguard/barrel retainer, KEKwave brace, the minimalist barrel retainer cap, and the MOE style pistol grip are designed by insertmeow
* NOTE: The mag-holder foregrip model does not have a hole for a set-screw. However, one method of adding a fastner
is to drill a 2.5mm hole from the top side of the grip, and to install a 3mm sheet metal screw from inside the mag well of
the grip. That way, the fastner is hidden and can be tightened or loosened with a screwdriver from inside the grip. Same
for the MP5-style foregrip.
