There is an easy way to vaccinate yourself against the desire to spend this kind of money on this gun......go shoot one a bit, and after that a suppressed SBR version will do you just fine. People who've never dealt with this gun in it's full auto guise have no personal experience of how absolutely filthy that thing gets, and how quickly. Additionally, recall that the envisioned purpose for this gun was to be used with the selector set to semi. Witness the fact that all of the Bundespolizei you see patrolling the airports in Germany have an MP5 with a trigger group installed that allows only semi auto fire. Full auto is an option. but not a great one. When I was stationed there, the Polizei in West Berlin would use the Rose Range complex. They had a full body silhouette target, with arms and legs, and were practicing putting rounds into those arms and legs. On semi. Knowing all this, if the desire to crank rounds downrange still exists, Franklin will do you just fine.
