Just a thought on the M4 buttstock for those that feel it is sub par.. I’ve seen a lot of collapsible stocks, and I can’t recall any that come close to the quality of the M4 legacy buttstock. Not often do you see an aluminum frame collapsible buttstock, everything these days is made out of polymer. It is one of a kind imo, and this is why it is so expensive, I haven’t seen any clones but I doubt clones have aluminum buttstocks.
