CAA Airsoft Division Roni-B Pistol Carbine Conversion (Black – M9 – CAD-SK-06-BK)
The CAA Airsoft Division Roni-B is a pistol carbine conversion kit, finished in black, that turns a compatible M9 gas blowback pistol into a compact, shoulder-fired carbine. You simply fit your pistol into the kit, and it gains a stock, rails, a foregrip and a longer sight radius, making it far easier to shoot accurately and much more capable in a game.
CAA is known for its Roni kits, which have become one of the most popular ways to get more from a gas pistol without buying a whole new replica. The Roni-B suits players who already own a M9-pattern GBB pistol and want a compact primary for CQB, and anyone who enjoys the futuristic look of a pistol carbine.
Design and features
A UK retailer listing for the Roni-B (in dark earth) describes a high-density polymer body with CNC aluminium rails and aluminium and steel trim, a full-length top Picatinny rail, two side rails and a front rail carrying a folding vertical foregrip with a built-in hand stop. It lists flip-up aperture sights that can be removed, ambidextrous charging handles and QD sling sockets front and rear on both sides.
The sliding stock adjusts for length of pull and has an adjustable cheek riser, and the stock includes storage for a spare magazine. The retailer gives a weight of around 1.93kg.
How it works
The kit is a shell that the pistol sits inside; it does not include a pistol, magazines or any internals of its own. Your pistol still does the shooting, using its own magazines and gas, while the kit gives you a stable shoulder mount, a forward grip and room for accessories. Because the pistol is held firmly, the kit adds stability rather than power.
The pistol can be removed again when you want to use it as a sidearm. Follow the fitting instructions carefully, make sure the pistol is unloaded with the magazine removed before fitting or removing it, and check that it is securely locked in before use.
On the field
Add a red dot to the top rail and a torch to a side rail and the Roni becomes a very effective CQB tool. The stock lets you take steadier, more accurate shots than with a pistol alone, which is especially helpful for newer players. Have the pistol chronographed in the kit at your site before play.

Compatibility
The retailer lists the Roni-B for TM, KJW, KSC and WE M9/B9-pattern GBB pistols, describing it as a drop-in fit for most TM-based M9 designs. Please check your pistol against this before ordering, as fit can vary between makers and models.
Rail accessories in standard 20mm (Picatinny) fit the kit’s rails. Use magazines and gas recommended for your pistol.
Care and maintenance
Remove the pistol from the kit after use and look after it as normal: use the gas recommended by its maker, apply a drop of silicone oil to the magazine seals now and then, and store magazines with a little gas in them.
Wipe the kit over after damp or muddy games, check rail screws and the stock lock now and then, and keep the pistol bay free from grit so the pistol seats securely each time.
Who is it for?
The CAA Roni-B is for owners of compatible M9-pattern GBB pistols who want a compact, accurate carbine for CQB without buying a new replica, and for collectors of distinctive conversion kits.
Please note: The pistol, magazines, gas and BBs are not included. Always wear suitable eye protection, and full-face protection where your site requires it, when using or testing any airsoft replica.
