"Amazingly enough there was not many things modified to make this gun work, Seamus made up what he calls an "articulating ejector" that feeds and strips the links as well as doing ejecting duties. This is device has a patent pending so I won't show any pictures of it, nor go into it's actions, lets just say that it works, and works flawlessly.
This gun looks BONE STOCK from the outside, nothing gives away what hides inside nor what it is capable of. Since we got it to work semi-auto, we decided to go a step further and make it, er.more "fun" Seamus scurried back to his corner and whipped up a fire control device for the ol' 45."
I am still having trouble figuring out how this 1911 can strip the belt link and eject it with the spent brass while feeding a new round into the barrel. Given that ejection works with the slide traveling backwards and loadint a round into the barrel occurs with the slide moving forward, there is no way this could be functional.
From that site...
"One think I did notice was a number "3" on the rear sight as I looked at it in my firing stance..I pulled the trigger and 3 rounds fired out damn near touching each other on the target. Seamus reached up, grabbed the rear sight and turned it 90 degrees to the left..it said "2",I pressed the trigger.damn, 2 rounds neatly centered. Slowly I got the clue, the rear sight IS the fire control.options for 3 and 2 round burst, single shot and FULL AUTO are all controlled by twisting the sight. He somehow
made the sight to twist (sort of along the lines of the HK rifles) instead of different aperatures, it has different settings for the rounds to be fired!"
Wow, almost as cool as the whole belt fed concept, the guy has a fire control selector on the rear right that is dovetailed into the gun. Even if the sight could pivot, you could only use it so sight when is was forwards or backwards, but NOT when it was turned to the side. Note that there is no sighting groove running perpendicular to the gun, hence if rotated 90 degrees, the sight is not functional.
I really like the part about the patent pending, hence not showing us the details of ho the gun works. What a convenient excuse. You have to wonder if the smith was licensed such that he could legally built machine pistols.
