I hope someone can give me some insight into the following regarding H&K machine guns.
1) With a machine gun with a sear pack; the sear is the registered part right? Thus it (and its trigger housing pack) can be transferred to any host and that host becomes the machine gun. Thus if you remove it and transfer to another host, the machine gun (let's say its a HK91) turns into a regular title I gun if you just place a regular 0-1 trigger pack into it, right?
2) Will I need to take into considering any receiver configurations on the sear/trigger pack with the new host? I understand there are a couple of different configurations to how the trigger/pistol grip housing fits into the receiver in these H&K guns (pin configuration and interfaces).
I shot an MP5 recently and I am very curious about getting my own especially since H&K is putting out their own SP5.
