Oh, they work fine, you can even build your M14ganov now.
It's kinda annoying that the M14 stock is just one big solidly grouped lump like in the old PMG rather than being possible to break down; I understand that's what the stock actually
is, but it would be nicer for actually using it if it was divided into "handguard" and "stock" sections. Same with the grip of the AUG.
