Do you have an AR you would like to fold up and put in a bag, without having to deal with taking the upper and lower apart? Then the LAW is great, and I would definitely recommend going with the latest model (I had a gen2 for a while and had issues with the carrier extension coming loose, rotating, and snapping off the proprietary buffer retaining pin, which of course fell into the FCG and locked the whole damn thing up). The Gen3 gets rid of all that, using a stock retaining pin and an orientation-agnostic carrier extension. But as others have mentioned, there is definitely a weight penalty. My 11.5" pencil-barrel SBR ought to be light... but with the LAW folder and Steiner 1-4x, it's a chonky boi for sure. But... it fits in a backpack, a feature I mostly use to bring it with me when a bunch of us go eat lunch after a 2-gun match, so I don't have to leave a gun in my truck unattended.
