Every Micro RONI kit level uses the same chassis. What changes is what ships in the box.
The Gen 4X and Gen 4 both come in four levels. Each one adds parts to the one before it, so the choice is simple once you know what you already own.

Who Each Level Is For
Kit only

You already own an optic, a light and a sling, or you want to choose each part yourself. Micro RONI Gen 4X kit · Gen 4 kit

The parts most people add first: thumb rests for grip, flip-up sights so you can aim without an optic, and a one-point sling. Gen 4X Basic · Gen 4 Basic
Advanced

Everything in Basic plus a flashlight and a carry bag, so the kit is ready for low light and easy to carry. Gen 4X Advanced · Gen 4 Advanced
PRO

The full setup with a red dot sight on top. One order, nothing left to buy. Gen 4X PRO · Gen 4 PRO
Build It Your Way
Want the Basic kit plus a muzzle device, or a different light? The Micro RONI Builder lets you stack extras on any kit level and drops that exact setup in your cart. Lights, the muzzle device, thumb rests and the hard case are also sold on their own in Micro RONI accessories.
Check your local regulations before choosing a stock. In the US, a shoulder stock on a pistol may require NFA/SBR registration.
