Law Tactical’s AR Folding Stock Adapters aren’t cheap but they are good so you know it was only a matter of time before the knock-offs started showing up. Most of the knock-off adapters are visually similar but should be very easy to spot due to their noticeably lower quality hardware and sling stud (genuine Law Tactical AR Folding Stock Adapters feature a QD sling socket, not a stud). The stud can be seen at the bottom of the adapter in the image below.
These counterfeit adapters are available under a number of brand names and from a variety of sources. If you are in the market for a folding stock adapter, make sure you know what to look for. As always, it’s best to stick with an authorized dealer when purchasing new.
