Top 7 Best Glock Carbine Conversion Reviews

Part of Command Arms Accessories’ most popular line of products, the CAA MCK P-40 Gen 4 Micro Conversion Kit is a special edition Glock Micro Conversion Kit with a unique paint job. This color scheme and style is inspired by the WW2 P-40 fighter planes flown by the Flying Tigers in the Pacific Theater.

This model fits most full-size and compact 9mm and .40 caliber Glocks, from the original Glock 17 to the new Glock 45. Installation is easy and convenient; no need to disassemble your pistol. Simply snap it in, and you’re ready to go.

The kit features a long top-side Picatinny rail, which can accept a wide array of iron sights, red dots, and scopes. I recommend pairing this kit with a set of Magpul MBUS Flip-up Sights or a SIG Sauer Romeo 4H Red Dot Sight to get the most out of your Micro Conversion Kit.

The stabilizing brace can be folded to the right, making your Glock converted with the CAA MCK compact enough to fit into nearly any backpack. This is a must if you enjoy shooting in the great outdoors.

Who Should Get This? 

You should get this if you want the most convenient and fully-featured Glock carbine conversion kit available on the market today, particularly if you like the P-40 paint scheme.

A newcomer to the world of stabilizer brace kits and carbine conversions, the Recover Tactical 20/20 Stabilizer Kit is a simple yet sturdy product made of glass-reinforced polymer. Its most attractive feature is compatibility with over 40 Glock models

As long as your pistol has an accessory rail and is not one of the large-frame models (.45 ACP and 10mm Auto), you can use the 20/20 Stabilizer Kit on your pistol.

Whether you use it 1-handed or 2-handed, the Recover Tactical 20/20 Stabilizer Kit can improve your accuracy and allow you to get the most out of your Glock, no matter the chambering. The system is designed not to interfere with your existing sights and is even compatible with red dot sights. It’s perfect for your red dot-equipped Glock MOS.

Affordably priced, this Stabilizer Kit is a great first choice if you are new to stabilizing braces and carbine conversions in general.

Who Should Get This? 

You should get this item if you’re looking to purchase your first Glock carbine conversion, and you want a fairly-priced, high-quality product.

The Micro Conversion Kit line of products by Command Arms Accessories is one of the best ways of turning your Glock handgun into a convenient, short, pistol-caliber carbine.

This model is a Gen 4 version and will fit various full-size and compact 9mm, .40 S&W, and .357 SIG Glock models, from the G17 to the G45. It is compatible with every Glock Generation from Gen 3 to Gen 5. Whether you’ve recently purchased one of the latest models or need to give your old Gen 3 a new life, the CAA Glock MCK is sure to expand your pistol’s capabilities.

The MCK is available in many different colors besides classic black, such as Flat Dark Earth, white, red, OD green, or even hot pink.

Its included, convenient front-mounted magazine holder lets you carry an extra magazine directly on the system, ensuring you always have ammunition on tap and allowing for a quick and easy reload.

Who Should Get This? 

You should get this if you want one of the best Glock 17 carbine conversion kits available today for your Glock chambered in 9mm, .40 S&W, or .357 SIG.

If you plan to convert your Glock into a convenient pistol caliber carbine, but your favorite Glocks are .45 ACP or 10mm Auto, this version of the CAA Glock Micro Conversion Kit is specifically designed to fit the slightly larger frames of the Glock 20 and 21.

If you love shooting .45 ACP or 10mm Auto, you probably also enjoy using the hotter ammunition. After all, it’s half the appeal of this chambering to have Magnum power in a handgun.

With the CAA MCK for Glock 10mm and .45 models, not only is it easier and more comfortable to shoot powerful 10mm or .45 loads, but you will also be able to stay on target and keep those steel targets swinging.

As long as you keep in mind that this specific model is meant only for full-size .45 or 10mm Glocks (Glock 20, 21, 20SF, and 21SF), you will be able to get the most out of it. 

Who Should Get This? 

You should get this model if you want a CAA Micro Conversion Kit for your large-frame Glock pistol, chambered in .45 ACP, or 10mm Auto.

The ultimate DIY project for a gun owner is perhaps manufacturing a firearm of their own. This practice is not only perfectly legal (so long as you keep it for personal use), it’s also quite fun. With the advent of Polymer80 frames, you can purchase an 80% finished pistol frame, complete it yourself, and install Glock Gen 3-compatible parts on it.

There’s no reason to leave your Polymer 80 Glock out of the carbine conversion fun. CAA strikes again with the Micro Conversion Kit for Polymer80 (MCKP80). This model accepts all version 1 and version 2 Polymer80 frames compatible with either full-size (G17/G22/G31) or compact (G19/G23) parts.

The kit also includes 2 sets of charging handles; the first set is for genuine Glock slides, while the other is for Polymer80 slides. It is also suppressor-ready, so if your handgun possesses tall sights and a suppressor, the CAA MCKP80 will still accept it without problems.

Who Should Get This? 

You should get this version of the Micro Conversion Kit if you possess a Glock with a Polymer 80 frame and you wish to convert it into a carbine.

Although this is an older generation, the Micro Conversion Kit Gen 2 for Glock 9mm/.40 is still a quality product, with all of the features and advantages you’d expect from a good carbine conversion kit.

I’ve found that for compact Glock models, such as the Glock 19 or the Glock 45, the MCK Gen 2 is a great fit. Installation is straightforward; simply follow the detailed instructions provided in the box, and you’ll convert your Glock in no time.

Although this carbine conversion kit comes with many useful features, such as an included Picatinny rail for optics or a front-mounted spare magazine holder, I recommend purchasing the CAA Advanced Upgrade Kit to get the full potential out of your MCK.

With a Glock 19 fitted to the MCK Gen 2, the Advanced Upgrade Kit, and 2 high-capacity magazines, you get not only a great toy for fun at the range but also a handy firearm for self-defense. This configuration is recommended for use as a truck gun because the stabilizer can be folded and stowed in a relatively compact space.

Who Should Get This? 

You should get this if you want a convenient carbine conversion kit for your full-size or compact Glock pistol for fun at the range or personal protection.

The original Micro Roni has a real stock and is an NFA item. It legally turns your pistol into a short-barreled rifle, and doing so would require you to pay a tax stamp and file paperwork if you wanted to use it as a civilian.

The Micro Roni Stabilizer Pistol Carbine Conversion is the same product, but it features a stabilizing brace instead of a shoulder stock. With this model, there’s no need for tax stamps or ATF paperwork.

I find this carbine conversion kit to be one of the most convenient; it has a long top Picatinny rail to fit iron sights or the optics of your choice. Try installing a holographic sight and magnifier combo, such as the Holosun HS510C + HM3X magnifier, which significantly improves your Micro Roni’s versatility.

The Micro Roni is an older model. It is not designed to accept Gen 5 Glocks but will take full-size and compact Gen 3 and Gen 4 models without problems. If you have an older Glock lying around and you need to give it a new life and purpose, install it into the Micro Roni; you will not regret it. 

Who Should Get This? 

You should get this if you have an older Gen 3 or Gen 4 Glock in 9mm or .40, and you want a short, compact carbine conversion kit for it.

Best Glock Carbine Conversion Overall

The CAA MCK P-40 Gen 4 Micro Conversion Kit is not only fully-featured, but the stylish, P-40 inspired design is sure to be noticed by others.

The CAA MCK P-40 Gen 4 can extend your practical range at up to 100 yards, not to mention it will improve your accuracy and stability. Simply put, there is no better way to make your Glock more effective in any situation, from the range to personal defense.
