Description
The Micro Roni Gen 4 with stabilizing brace takes everything that works about pistol conversion kits and packages it into something you can deploy in seconds. Just drop your Glock 17 or 19 into the aluminum and polymer chassis, lock it in place, and you've got a carbine-style platform that actually improves your shooting. No gunsmithing, no disassembly, no headaches.
What Makes the Gen 4 Stabilizer Different
This isn't your grandpa's conversion kit. The Gen 4 generation brought real improvements that matter at the range. The stabilizing brace attaches to your forearm with an adjustable nylon strap, giving you rock-solid platform control for precise shot placement. The longer, extended brace design works way better than earlier versions, and you get ambidextrous charging handles and trigger guard safety, which means it works equally well if you're right or left handed. There's a captive charging handle that stays put and an open hatch design so you can access your pistol's slide stop without disassembly.
Built for Accessory Support
You get a full-length Picatinny rail on top, perfect for mounting red dots, magnifiers, or night vision. Two additional side rails at three and six o'clock positions give you mounting points for vertical grips, flashlights, or whatever else you want to bolt on. There's an integrated magazine carrier up front for quick reloads, and if you want to go minimal, it's clean and compact. The flared ejection port handles weaker ammo better than older designs, and switching between your Glock 17 and 19 takes seconds with the adjustable platform.
Reliability Where It Counts
Built with aluminum construction and a solid polymer body, this kit is proven in the field and trusted by enforcement and enthusiast communities. It's lightweight enough to handle easily but sturdy enough to keep your optics and your shots on zero. The Glock 17's longer slide and heftier recoil mass work particularly well in this platform, giving you more forgiving timing and better balance when you've got a light mounted up front.

Frequently Asked Questions
Does the Micro Roni G4 require any modifications to my Glock?
No, the Micro Roni Gen 4 uses a drop-and-lock system that requires zero modifications to your pistol. Simply insert your Glock into the chassis and lock it in place. Your pistol can be removed at any time without tools, and nothing about your gun changes.
Will the stabilizer brace work equally well for left and right-handed shooters?
Yes, the Micro Roni G4 Stab is fully ambidextrous. The charging handle, trigger guard safety, and brace design all work seamlessly for both right and left-handed operation. The right-folding stock doesn't limit functionality regardless of your dominant hand.
What's the main difference between this stabilizer brace model and a folding stock version?
The stabilizing brace version wraps around your forearm with an adjustable strap for control and can be shouldered. The folding stock version would be configured as a short-barreled rifle and requires a tax stamp. This stabilizer brace version offers the same control benefits without that requirement, making it ready to use immediately.
Can I use the Micro Roni G4 with optics and other accessories?
Absolutely. The full-length top Picatinny rail lets you mount red dots, magnifiers, or night vision. The two additional side rails at three and six o'clock positions work for tactical lights, vertical grips, or other attachments. There's also an integrated magazine carrier built into the front for faster reloads.
