At a glance, a folding stock or collapsible stock is one that is not fixed permanently and does not remain static, when referring to the length thereof.
One of the many intended uses of a folding AR-15 stock is to enable the shooter to alter the length of pull.
An important consideration to bear in mind is that all folding stocks are collapsible in nature, but not all collapsible stocks can fold.
Our Guide to 6 of the best folding stocks on the market today
Before any new purchase, it is advisable to do your homework to ensure that you know all the options on the market, their advantages and drawbacks.
This way, you’ll be armed with sufficient knowledge to make an informed decision.
Magpul AR-15 CTR Stock Collapsible mil-spec W-Folding stock adapter
This collapsible, polymer-based folding stock comes available for purchase in a beautiful matte black finish. It makes this proud masterpiece from Magpul look great, especially as it is such a versatile product. It allows the rifle to fit the shooter and not the other way around.
This Compound/Type-restricted folding stock is compatible with AR15 and M16 rifles. It was created to be ready for fast-paced action, and the aerodynamic A-line frame protects the release hatch from accidental firing.
A perfect pairing is the Law Tactical Gen 3-M Folding Stock Adapter and the outstanding Magpul AR-15 stock. This powerful union allows the shooter to operate his or her rifle with ease. It will also ensure that the gun will be more compact.
With the rifle taking on a more condensed form, it will decrease any risk of snagging on clothes or other obstacles the shooter may encounter.
The incline in the cheek weld provides the shooter with increased stability and comes in two variants: the Mil-Spec and Commercial-Spec. The commercial-spec model’s selling point is that it comes with an expanded rubber butt-pad half an inch thick.
That is a popular choice, and such stocks often sell out as quickly as the inventory comes in. When using this product with the Law Tactical Gen 3-M Folding Stock Adapter, you will have a portable weapon at your fingertips with features such as adjustable hinge tension.
- Auxiliary friction lock presents a decrease in wobbling.
- Lock spring made from a durable chrome-silicon provides longevity.

It is made by forging a rugged A-line frame that is light, super comfy, and offers the operator ample bolstering. This folding stock’s contour is more spread out than a standard issued M4 stock, aiding the operator with a more stable and rigid cheek weld.
The sleek outside surface and protected release lever act as barriers against snagging of any kind. A concentrated spring-release lever offers speedy length-of-pull modifications without leaving uncomfortable impressions on your hand.

It’s seven and a quarter inches in overall length and five and a quarter inches in height. The Mil-spec version fits 1.14″ O.D carbine buffer tubes.

What is an AR-15 Folding Stock?
Folding stocks are found on AR-15s and similar rifles. This stock type makes the rifle shorter, so it is easier to carry from one environment to the next and makes concealment easier.
These types of stocks are suitable for operators and professional shooters where the weapon needs to be drawn quickly, but where the weapon’s stability and control play an integral part in hitting the target.
Why get an AR-15 Folding Stock?
Among the many reasons to buy an AR-15 folding stock, three stand out.
With a compact version of the rifle, you will find the following to your advantage:
- Easy concealment.
- Folding stocks save a full inch of overall length.
- It is so compact that if it’s in a bag, it does not give away its presence at all.
- You want to save as much space in your gun safe as possible to let all your weapons accessories to fit.
As an operator who needs to move from one environment to the next quickly, it is in your best interest that a bulky weapon doesn’t impede your movement. The following gains await you in terms of portability:
- Being shorter, it is easier to transport than the full-length version.
- When the weapon is not in use, the stock allows it to be folded.
- A smaller bag can be used to transport the gun, instead of the traditional long case.
- Storage is more convenient, and the weapon is ready to be fired in a matter of seconds, by flicking the stock.
- A gun rack does not have to be mounted on the vehicle to transport the shortened rifle.
Alternative to AR pistols
A folding stock negates the need for an AR pistol.
- Shooting is made simpler, so you don’t have to carry an additional weapon.
- The kick from the rifle is less with a foldable stock. The only difference between an AR rifle and an AR pistol is the absence of a stock on the pistol version, so the pistol is harder to control.
- There is no real difference in size, so carrying two weapons of a similar nature is pointless.
What to Look For in the best AR-15 Folding Stock Adapter
There are a few key considerations when deciding on an AR-15 folding stock adapter:
Stocks can be made from a few different materials, each presenting its own pros and cons:
- A great all-purpose material
- All-weather resistant
- If it gets scratched, it might not look nice, even though it is durable
- It comes with DLC coating, making it resistant to corrosion
It is better to spend a few more dollars to get a foldable stock that can withstand time, hard use, and the elements. Some brand names synonymous with quality folding stocks are:
- Law Tactical
- B5 Systems
Easy to Install
Some stocks wobble. Some are easier to install than others. Again, this is a personal choice.
- Look for a “drop-in” adapter if you want the easiest option to install.
- If you are looking for a tight or snug fit, a drop-in option will give you some play or wobble, so go with a traditional option.
- If you are in the field, you want to easily snap the stock in place without worrying about carrying a tool pouch.
- Only pick a non-drop-in adapter if you can install it.
Before making any purchase, ensure that you have conducted proper research into which folding stocks are compatible with your rifle.
- Visit gun stores and ammunition stores and get a sense of the look and feel in person.
- Speak to the experts at the gun shop about your weapon and your unique requirements.
- The slight differences in the mil-spec versions vs. commercial-spec versions of folding stocks might also mean the difference between the stock being compatible or not. For example, a commercial buffer tube or receive extension won’t work with a mil-spec tube.
Is This For Real? Doesn’t the AR-15’s Buffer Tube Prevent Stocks From Folding?
Apart from FoldAR, which produces a range of folding AR rifles and pistols, aftermarket products can make your AR fold.
Enter the LAW Tactical Gen-3 Folding Stock Adapter. The alpha and omega to all of your folding stock requirements. The best feature is that it does not compromise buffer integrity at all.
