Description
The Micro-Roni carbine conversion kit is an easy-to-use, full-polymer upgrade designed to transform your G-Series P320, M17 or M18 pistol into a compact, shoulder-fired carbine platform. Built for speed, stability and pure visual impact, this kit takes your pistol from sidearm to centre-stage skirmish weapon in minutes.
Compatible with SIG Sauer ProForce/VFC and WE P320 M17 & M18 GBB pistols (with some other models fitting with modification), the Micro-Roni features a three-point 20mm Picatinny rail system, including a full-length top rail for optics and two side rails ideal for torches and lasers. This gives you massive flexibility when it comes to customising your setup with accessories to suit CQB or outdoor play.
At the front of the kit is a ready-mag foregrip, allowing you to store a spare magazine inside the grip for lightning-fast reloads. The foregrip also incorporates a trigger-block safety, preventing accidental trigger access, a welcome feature when the pistol’s standard trigger lock isn’t accessible inside the chassis. An included torch push-fits neatly into the front of the kit, providing reliable illumination straight out of the box.
To further enhance handling, the Micro-Roni includes two gas pedals / handstops, which can be mounted to the rails. These provide a comfortable, grippy thumb rest to help stabilise the gun during rapid fire. Also included is a polymer slide cover with extended ambidextrous charging handles, allowing you to rack the slide quickly and positively to chamber a round with ease.
Installation couldn’t be simpler; the pistol slots into the chassis in around two minutes with no tools required. Once installed, the pistol sits firmly with zero rattle, thanks to the updated locking mechanism, which pushes forward to secure the pistol, while also locking into the front pistol rail for added stability.
Rounding things off is a folding stock, making the Micro-Roni easy to transport and ideal for tight CQB environments. Whether you’re building a high-speed indoor setup or just want to change the aesthetic and handling of your P320 completely, the Micro-Roni delivers performance, practicality and undeniable cool factor in one sleek package.
