Questions
Which Glock 20 / 21 versions fit?
Gen 3 and Gen 4, plus the SF short-frame models. Gen 2 and Glock 21 models with a full Picatinny rail are not supported.
Naked, Basic or Advanced?
Naked is the chassis and 16" barrel. Basic adds polymer backup sights and a one-point QD sling. Advanced adds a micro red dot and an absolute co-witness riser on top of that.
Threaded or unthreaded barrel?
Pick threaded if you plan to run a muzzle device or a suppressor.
Is it legal?
With its 16" barrel the APEX is designed to comply with US federal law. Check your state and local laws before you order.

The Full Rundown
Your Glock 20 & 21, rebuilt as a 16" bullpup carbine.
The META Tactical APEX turns your Glock 20 or 21, Gen 3-4 or SF, into a compact bullpup carbine with a 16" drop-in barrel.
Why We Like It
Most pistol kits keep the short pistol barrel. The APEX swaps in a 16" barrel and puts the action behind your hand, so you get rifle-length accuracy in a package shorter than most carbines.
The Good
- 16" drop-in barrel
- Very compact bullpup layout
- Fully ambidextrous
- Built-in cheek rest and 6-position stock
- Picatinny top rail plus M-LOK
The Bad
- Not for Gen 2 or Glock 21 with a full Picatinny rail
- Optics-ready slides must run without the optic mounted
