Product Description

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

Perfect add on to my MK18, easy to install!

The build is of high quality, strong and durable. Installing this folder was a breeze and the FDE closely matches Magpul’s FDE more than B5 or BCM. Either way I can now fold my MK18 SBR into my backpack which is pretty sweet.

Solid and sturdy

I've been eyeing the folding stock adapter for a while now and so glad I bought it. It feels great and other than the extended reach shoots just like before I installed.

Simple and strong

Easy to install and feels like it will outlast the weapon it’s attached to
