    II am considering a foldable stock adapter for an M4 type AR. I have a smaller pack for transport and think that a quick fold is better than reassembling two pins. Has anyone ever used a foldable stock adapter and are there any drawbacks with one?

    I went through the same thing and bought during the holiday sales, it is sitting in a box next to my coffee right now. Outrider58 convinced me in under a minute.

    I have two of the LAW adapters and they work fine. The only drawback is that they add about 8 ounces to the guns and they aren't cheap.

    I am running the law tactical on 2 of my SBR’s - recommended by outrider. They perform flawless, the weight addition is negligible

    Have a couple compact folders/PDW stocks. IMO the Law is the best to retrofit a standard AR15 to fold, but it's expensive, the adapter is bulky, and folding the tube and stock makes a really wide bulky package.

    IMO a far more practical solution is a Maxim collapsible. The CQB is awesome, and mine have been very reliable, works with standard BCGs, but needs their buffer/spring due to the short tube. Ends up collapsing down to just over 5", and far less bulky than folders while being able to be slung, stored or fired with the stock collapsed. Their SCW is even smaller at 4", but is more expensive and needs their carrier and buffer. I don't have one, but have fired them, and seems reliable, but not enough personal experience to claim "bet your life" reliability. The other decent solution is a bufferless upper like the FM products gen2, BRN180 or a couple other brands, and a compact slim sig side folder and pic rail adapter that threads into the buffer tube hole. THe FM is very reliable, others may be, but I don't have as much personal experience with them, a sig skeleton stock is a LOT slimmer and less bulky when folded than a buffer tube and LAW, and the buffer/action is not taken apart, left exposed and then put back together every time.

    Drawbacks? It might depend on how solid they are made. I've never run any accuracy tests on folders; however, for years now, I've been told by reliable sources that folders don't give the same accuracy as solid stocks. It makes sense if there is slop in the adapter, so that might be considered a drawback.

    That is why I bought the CMMG Dissent pistol which I hope to get out of jail on Wednesday. :D

    They are plenty accurate for the type of use they are made for. ;)

    There is a huge difference in the mechanism. Folding AKs, yea, no way to get a decent cheek weld, and they wobble. It can be tough to group anywhere near what a fixed stock could do. However many precision rifle chassis use folding mechanisms, generally locking or extremely rigid with 0 reduction in accuracy, still has all stock features and adjustments, but makes storage and transport easier. In that instance the only downside is perhaps added cost for the option.

    They look awesome, lots of "bufferless" designs out, and a couple cool things like bullpup or takedown chassis setups for them. I kinda want to build using a short 300BO or 9mm bufferless upper and A3 Triad bullpup chassis with one of my SBR lowers. At minimum they can fold without many drawbacks, and there are a lot of Sig compatible side folders around.

    I'd personally be looking at a bufferless upper and then using a proper picatinny rail folder. The LAW made a lot of sense when it came out, but the options have gotten much better.

    Too rich for me. I could start up a gofundme.
