AR Folding Stock Adapter GEN 3-M
AR Folding Stock Adapter GEN 3-M


Production of AR Folding Stock Adapters has not stopped. However, industry-wide demand has increased significantly. Our distributors/dealers are being supplied regularly. We recommend back-ordering for the fastest service.





The first and only folding stock adapter compatible with AR platform rifles.

The Law Tactical Folding Stock Adapter works with direct impingement or gas piston systems and fits A2, carbine, mil-spec or commercial buffer tube and stocks. It can be used with standard bolt carrier groups including: full auto, semi auto, 5.56 to .308.

The Law Tactical Folding Stock Adapter was designed for low profile transport of AR rifles in non-permissive environments. The adapter is ideal for any situation that requires a smaller profile weapon for transport and storage. Simple one-button release folds the stock. To engage, just unfold and fire. The stock automatically locks into place, requiring no fine motor skills.

Designed, built and assembled in the USA from CNC machined, 4140 steel.

The adapter does not affect gun 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. An integrated single point sling attachment point is included.

2 of 5 WON'T work with all tubes and stocks as advertised February 21, 2023
Reviewer: Josh adams from castalia, OH United States  
Bought this for a build with a brand new Magpul UBR Gen2 stock. The buffer tube for the UBR will not thread in to the folder past 2-3 threads without crushing the next thread. I successfully threaded the UBR buffer tube in to a Sylvan folder, stripped AR lower, and even one of the knockoff Law folders I bought three years ago with no problem. However, the legit Law folder will NOT work. Both the Gen 3-M Law folder and the UBR stock were purchased brand new from Primary Arms. Calls, emails, and Facebook messages to Law Tactical with pictures and receipts have not been responded to as of yet.

5 of 5 Flawless Function for Over a Year June 6, 2020
Reviewer: Jaycen Rigger from Wentzville, MO United States  
I purchased a Gen 3 folding adapter for my first AR build back in June of 2019.  The build is a 300BLK with a 9" barrel.  So, when folded this gun easily fits a backback or a duffel bag.

The folder has held up extremely well.  I have tightened the hinge bolt once, after the first few months, but it has held ever since.

There were only 2 cons for me - 1. It's heavy.  But it's also hardened steel and the action has remained smooth without any mechanical slop.  2. When I purchased the folder I also bought a captured spring system for my buffer.  At the time, Law Tactical did not have an option for a hollow BCG extension, so I had to purchase mine from Anarchy Outdoors.

As far as the product itself?  I would absolutely recommend it.
