AR-15/M16 GEN3-M FOLDING STOCK ADAPTER Reviews & Ratings

Law Tactical's steel adapter enables installation of a folding stock on any AR-15 to create a smaller-profile rifle for easy deployment from a vehicle or transport in non-permissive environments. Works with standard gas impingement OR gas piston system. Accepts A2, mil-spec M4-style, and commercial carbine receiver extension tube and almost any stock that fits them. Compatible with all standard bolt carrier groups, including full-auto and .308 size. Single-button operation for quick folding and unfolding and steel locking latch keeps stock securely in place when extended. Gen3-M has a lowered hinge to avoid interference when charging the weapon, and a setscrew keeps the adapter securely affixed to the receiver. Hinge tension is adjustable so you can choose how stiff the folding mechanism is. Includes special bolt carrier extension (no tools to install/remove). Current version utilizes standard buffer retaining pin and spring. Stock adapters feature a DLC coating, except for the Olive Drab Green which has a Cerakote finish.

its not very good at holdingth e buffer spring

After shooting about 20 rounds, folded the stock and the buffer spring shot out because the retaining pin had sunk down in the hole…..It needs a different retaining spring.

Not good quality

I tried installing this on an Anderson lower, after watching the video 2 times. The nut that attaches the folder to the lower started in just fine, then it stopped. It would not seat deep enough to re-insert the bolt block. I tried to back it out. The cheap piece of junk wrench bends. The nut is made of aluminum, so it started to strip the notches that the wrench fits into. So basically, I've taken a functional rifle, and ruined the lower because of the cheap nut and tool supplied by Law Tactical. I'm sending this back.

Rifle failed to cycle

Recently purchased this product for an SBR build. Installation was easy and straightforward. However, at the range, it did not allow the bolt carrier to cycle easily, The BCG seemed to hang up while passing through the Law folder. Bolt was stiff while trying to manually lock back the bolt (seemed to take much more effort to pull to the rear). Removed the hinge upon returning home. There did not appear to be excessive play in the hinge. The rifle would fire one round and then fail to cycle, and the forward assist had to be used to close the bolt.
