Legality of Pistol Carbine Conversion Kit

Before you go about applying one of the conversion kits in our guide, it’s critical to be aware of applicable laws. As these vary from each American state to state, it’s easy to end up on the wrong side of the law if not well-versed in your local regulations. 

Let’s start with some history. Your average handgun and rifle aren’t regulated by the NFA. On the other hand, short-barrelled rifles are. You must complete registration through the ATF and pay up taxes. So, how are a handgun, a rifle, or short-barreled rifle distinct? 

The solution is in Federal Law 27 CFR 478.11 (USA law). Handguns have a short stock and can be held and fired with only a single hand. A rifle is a weapon envisioned for firing from your shoulder. Short-barrelled rifles have barrels under 16 inches long or have an entire length of under 26 inches. This includes folding stocks when fully extended unless the stock can be taken off. 

Let’s piece it all together: moving from a handgun to a rifle needs no special NFA compliance. However, you should be aware that if your handgun winds up firing from the shoulder and doesn’t conform to the 16-inch barrel-length prerequisite or 26-inch overall-length requirement, you have legally created a short-barrelled rifle. As such, it will need to be registered to the ATF and be taxed first. 

Now, if you add a vertical fore-grip, it gets into the foggy territory. It’s neither intended to be fired from the shoulder nor with one hand. The short answer is, it goes into the category of “Other” and has to be registered. 

You should also be informed of state laws, as this is the Federal Law we have summarised. You are probably aware that American states can and will at times pass laws to outlaw numerous accessories, and whether or not such laws are determined to be Constitutional may not matter in the short term if you’re found in defilement. 

If you find yourself in a situation you don’t comprehend or it appears to be a grey area, then get on the side of caution, as at a federal level, the violation carries severe consequences, including up to ten years of incarceration and simply isn’t worth going through it. 

The Types of Carbine Conversion Kits for Glock

There are a variety of carbine kits offered, each turning your Glock into something exclusive. Some basic alterations include: 

Shoulder Stock 

This may be done an assortment of ways, often by implementing a holster that can be used as a shoulder stock, attached to the pistol’s grip. 

Front Sliding 

With this feature, the front end of the kit can slide forward, allowing mounting of various accessories. 

Foldable Stock

With some kits, it’s possible to have a foldable stock, often removable. 

Increased Barrel Length 

Often joined with a shoulder stock, and also often elective in carbine kits, an increased barrel length can be added for additional accuracy. 

As you can see for yourself, conversion kits are not a one-size-fits-all answer, but rather are designed to find a custom solution to a common problem: the limits of the Glock. While the Glock is an outstanding handgun, conversion kits allow it to easily function more like a rifle. 

The Criteria: Aspects to Consider Before Buying Glock Conversion Kit

Choosing a carbine conversion kit can be complex, with many aspects on a buyer’s radar. You’ll want to consider the following aspects and features: 

Dimension (Size and Weight) 

A carbine conversion kit can radically change the appearance, size, and weight of your gun, so you will unconditionally want to be sure you know what you are getting into. It goes without saying that you will definitely need to consider where you want to store your weapon, how you will be using it, what you are comfortable holding, and so on. 

Build Quality 

There are so many kits out there and quality is a huge spectrum. In particular, you want to pay close attention to the quality of the parts used and make sure that the manufacturer performs demanding to test on their components. 


It is very little to no point in reaping the benefits of conversion if your accuracy suffers too much. While for short-range shooting this may be of a lesser concern, it should be paramount for anyone hunting or sport shooting. 

Ease of Installation and Methods 

A conversion isn’t among the simplest of alterations one can do. That’s not to say it’s extremely difficult, but it will be as difficult as the producer makes it. A really great kit will have clear instructions and apply design options that make the task as simple as possible.
