As noted, the G3 steel trigger group is an original factory component made in Germany by HK. These trigger groups were stripped from service rifles used during the 1950s, which means you are not only getting a complete, fully-functional trigger group, but a piece of history as well. Unlike the Navy-style trigger groups that are commonly found today, the housing for these trigger groups is constructed using steel as opposed to polymer. These are the trigger groups that were originally found on the G3A3 variant. On the G3 rifle, the trigger group is mounted to the receiver as well as the buttstock via the lower locking pins. Each steel trigger group comes with one olive drab pistol grip mounted to the frame. This component is extremely important to the functionality of the G3 as it houses all of the fire controls, including the trigger, sear, hammer and selector switch.
Spare parts and accessories are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly. This is especially true of the trigger group, which houses all of the fire controls. Keeping this component of the rifle in working order should be made a top priority. If a part breaks or fails, a repair or replacement is necessary.
