dschmid4 Posted August 24, 2020 Share Posted August 24, 2020 Just picked up my new M4 with collapsable stock. This is a new OEM purchase from my local gun shop; not a used item. Unfortunately the stock doesn't collapse. It appears the flats/grooves on the stock tube are very limited and there is no way this will fully collapse. Are there other versions of this and did I perhaps get the incorrect tube installed? Quote Link to comment Share on other sites More sharing options...
