 Certain variants have a receiver-mounted dovetail adapter that is used to mount various optical sights.The standard stock found on the Galil is a rough-copy of the FN-FAL Paratrooper stock, with modifications for simpler production and ease of use.Unlike the FAL folding stock, the Galil uses no locking button and is operated entirely by a pin and spring pivoting mechanism; to fold the stock, the "L" bracket on the stock portion is pressed down to where the spring is fully compressed and the entire stock is allowed to pivot on the buttstock hinge.
