Designed, built and assembled in the U.S.A. from CNC machined 4140 steel. The adapter does not affect firearm function when unfolded in the standard fire position. The rear portion of the adapter is built to the same specifications as a standard receiver to ensure maximum compatibility. A single point QD sling attachment point is integrated in the adapter, so you can quickly attach your favorite sling.

The hinge, housing, locking lug, and latch are all low-profile to eliminate interference when manipulating your weapon system. The stock adapter also comes with a set screw, so you can tighten it down and prevent the buttstock from loosening. The entire accessory is coated in an extremely durable DLC finish for long-lasting corrosion and wear resistance. It also uses a Mil-Spec buffer retaining pin and replaceable O-rings on the bolt carrier extension to prevent damage in the folded position.

Works great easy to install and seems durable. If you are breaking in a barrel bring another lower as it is a bit more cumbersome to take down. What? You don't have another lower? Buy one already they are inexpensive.

Solid and well made folding mechanism.


I just ordered this item, but I had the chance to check it out earlier this month at Law's booth at the Harrisburg, PA Outdoor Expo. I tested it for probably 10 minutes. The display item had been checked out hundreds and hundreds of times in the days before I got there, and remained a solid folding mechanism that was simple to use, fast, and locked up great. It does add about half a pound of weight, but that comes with the all-steel mechanism. Just flip the stock opens and it locks right up. An extremely well made item, and makes your AR a bit more compact for storage.

Solid construction


I used this on a 9mm build with kaw valley bcg. Knocked out the roll pin on the Bcg, removed the spacer, and cut off a section to accommodate for the law's Bcg extension. Everything is working great. That fit and finish on this thing is fantastic. Rock solid. I am very impressed with this product and will be buying another for my .556 pistol

This folder is great


I got this for a 300blk pistol build it's connected to a Kak pistol brace kit. I read some folks had a little play in it mine is solid. When it's folded it stays folded until you unfold it tight. It cycled fine with sub and supersonic loads I run a 9" bcm upper and the buffer is a standard carbine that came with the Kak kit.

Problems fixed by stellar customer service.

Great piece of equipment, however, the one that I received was missing some parts and after trying to communicate with law tactical (which went no where) I finally contacted Primary Arms for assistance. I had the actual pleasure of communicating with David, a fellow vet, who was not only able to correct my issues (including sending the missing parts). He was prompt and answered my questions to the best of his abilities. I am most impressed by the level of commitment Primary Arms has to its customers and I will definitely be returning for my next builds! On top of that, Primary Arms has the best prices on most things I have seen anywhere.

Law tactical folding stock review

I was concerned when I first purchased this unit. I was leary of a folding stock on an AR.<br>Well, this thing is ROCK solid!! I have been real pleased with the quality and finish of this product. Primary Arms had a good price at the time, so I bought one. Primarys Arms has a huge selection and real quick shipping!

Just installed my second Law Tactical folding stock adapter on a new build. I was very skeptical of this product prior to buying my first one last year. That quickly faded away. I have put over a thousand rounds and used my Law enhanced AR in two carbine courses now without a single hiccup. It integrates seamlessly with the SBA3 brace and allows me to keep my AR pistol in a normal Patagonia back pack in my truck. Installation is very easy and fast. The only negative I can think of is that it doesn't play well with some after market receiver end plates like the ASAP plate or ones that have sling attachments on the sides as they interfere with the Law Adapter, not allowing it to completely fold up. The adapter isn't cheap either but you are getting a super heavy duty product that can stand up to constant use and abuse and doesn't come loose or fall apart.

Was skeptical when I first saw the videos online. After reading several reviews and actually shooting one, I'm convinced it's a very solid setup. Being machined from 4140 steel, it's NOT lightweight, but it is incredibly strong.
<br> If you're on the fence, I definitely recommend trying one. You won't be disappointed.

Excellent LAW folding adapter

I'm very pleased with the LAW folding stock adapter. Simple installation, and very tight, strong lock up. Well worth the money. My 8.5" PSA 300BO pistol now folds to 19". Adds some weight, but behind pistol grip & actually balances the firearm better. Don't get the cheap copies, this is combat quality imo.

Wish I bought two when they were on sale.

How about it? Short stopper.
<br> I put the Law Tactical Folder on my 6.5 Grendel, and it preforms great. I wanted a small form factor without going to a SBR. Something that I could cary around in a small package while not letting prying eyes of those around me, know I'm in possession of an AR. The carbine fits nicely into my pack. I was quite concerned at first with the additional weight and extra length it added to the rifle. But after a year of living with the folder, this fits the bill nicely. Deploys quickly from the folded position, and folds just as fast, push the button and done.
<br>I'm thinking of buying another soon.

Great option to shorten weapon for storage and travel

Easy installation, seems robust and well made. Dropped it on a 300 BLK 10.5 pistol and like they say, folded it fits right in a standard size day pack even with a brace.

Great for breaking down a longer AR Pistol for backpack concealability.

I built an AR Pistol with this adapter, but I also purchased the JP Silent Spring for my buffer. The plunger that comes with the LT folder won't work if you have that buffer system. Now, all my parts play nice together in the back of the gun.

Solid adapter

Put this on a New Frontier 9mm build with a Hex tube and tail hook. Locks up very tight. Wish it locked in the folded position, but not a deal breaker. If you’re using this with a solid 9mm bolt, I had to cut about 1/2in off the steal weight that’s Pinned inside the carrier so the adapter can go inside it. Non issue with a 556 carrier. The adapter is made from quality materials, not Lightweight alloy. Solid piece
