Description
The Micro Roni G4 takes your Glock and transforms it into a compact carbine system without any disassembly of your pistol. Just drop it in and lock it down in seconds. The stabilizer brace attaches to your forearm with an adjustable nylon strap to give you real stability and control during shooting.
Micro Roni G4 Setup and Compatibility
This Gen 4 model works with Glock 17 and 19 in Gen 3, 4, and 5. The aluminum and polymer construction creates a lightweight, durable platform that keeps things simple. The kit includes an integrated angled foregrip and front magazine holder, so you get basic functionality right out of the box. One thing to know: it won't fit Glocks with extended slide releases or RTF frames with "fish gills" serrations.
Micro Roni G4 Rails and Accessory Mounting
You get a full-length Picatinny rail on top for mounting optics, magnifiers, or night vision. Two additional side rails let you attach lights, lasers, or whatever else you need. The ambidextrous charging handle and trigger-guard safety work from either side, making it equally functional for left and right-handed users. An open hatch design gives you easy access to the slide stop if you need it.
Micro Roni G4 Brace and Control
The right-folding stabilizer brace is the whole point for many users. It fastens securely to your forearm and minimizes the accuracy-robbing movement that can happen with just a pistol. When folded, it covers the trigger guard, so you can safely carry or sling the whole system. The extended brace is a practical design that works for most shooters and improves your grip significantly over holding a pistol alone. Add the serrated thumb rests separately if you want more recoil control.

Frequently Asked Questions
Do I need to disassemble my Glock to use the Micro Roni G4?
No. The beauty of the G4 is that you just drop your Glock into the chassis and lock it in place using the rear locking button. No field stripping required. Takes about 10 seconds.
Can I use the Micro Roni G4 with Glock 19X or Gen 5 compensated models?
Yes, Gen 5 Glocks and the 19X are compatible. The kit also works with compensated models. Just avoid Glocks with extended slide releases or the RTF "fish gill" texture, which aren't compatible.
What's included with the Micro Roni G4 Stabilizer?
You get the chassis, the stabilizer brace, integrated foregrip, front magazine holder, and three Picatinny rails for mounting accessories. Most common upgrades like thumb rests, sights, and lights are sold separately to keep the base kit lean.
Will I need additional accessories to use it effectively?
The G4 is functional out of the box with its integrated grip and rails. But many users add thumb rests for better recoil control, a red dot optic on the top rail, and a light. These are optional upgrades depending on your intended use.
