Questions

Do I need to take my pistol apart?

No. Seat your unloaded pistol in the kit, close the lock and it is ready. No tools needed.

Which option do I pick for my pistol?

Choose your pistol family in the Fits option: Glock 17/19 family, Glock 26/27, Glock Gen 6, CZ P07/09, CZ P10 or Beretta APX.

Does the pistol work with the stock folded?

Yes. The stock folds to the right and the pistol stays operable.

Can I add sights and a light later?

Yes. Thumb rests, flashlights, the muzzle device and more are sold on their own, or pick the Basic, Advanced or PRO kit to get them together.

Stock or brace: what should I know?

Check your local regulations before choosing. In the US, a shoulder stock on a pistol may require NFA/SBR registration.

Where do you ship from?

From Israel, worldwide. Registered shipping is free on orders over $199. Every product carries a 1-year warranty.

The Full Rundown

Drop it in. Lock it. Done.

The Micro RONI Gen 4X is the latest evolution of the kit that started the micro conversion craze. Your pistol drops in and locks in seconds, with no disassembly and no tools, and you get a stable, shoulder-supported platform with rails for everything.

Why We Like It

CAA kept everything people loved about the Micro RONI and fixed the small stuff: a captive charging handle that stays in the kit, a bigger flared ejection port that handles weaker ammo, and a triangular shroud that works with “Plus” muzzle accessories.
