The barrel has a groove. The pin itself is round on one side and flat on the other. This ensures that the pin will go in only one way. When the pin is pushed in, a ball bearing locks it into place. With the pin in place the barrel will not rotate. Is not compatible with the ws-66 hop up barrel.
But that means it is similar. I'm assuming there are no issues of barrel wobble with this design? Hmmm...something Warsensor should look into so I don't need an allen wrench to take my barrel off in the field.
I am not familiar with the ws-66, other than the barrels are not compatible. I cannot confirm if you need an allen wrench with the ws-66, but the SIM-5 does not require one. With the SIM-5 you just insert the pin and the ball bearing locks it into place.
If you look around their web site you will see that they do not manufacture all the parts them selves. In the FAQ they say how the parts are made from both foreign and domestic parts and are assembled in California. If you have a large quantity of markers waiting to be finished, but you are still waiting for one box of pieces, waiting for it seems to take forever.
What does the name of the owner have anything to do with waiting?
On that note, what does waiting have anything to do with the Sim-5 barrel?

The WS-66 had an issue with barrel wobble when the prototypes were sent to testers. To fix this, Warsensor installed a allen screw with a 3mm cap head to CLAP the barrel in place.
So, what you do is you install the barrel and insert the pin. Once this is done the barrel will not come out but will wobble a bit. Then you tighten down this screw so the receiver clamps the barrel in tight and eliminates all wobble.
It makes it a paint if you need to clean in the field...however out of 7,000 rounds I've broken only three balls...2 because of the detent being off and one because it got chopped when the marker ran out of CO2. In the last 5,000 shots...never a single break.
The Sim-5 barrel locks in place with a pin inserted horizontally beneact the barrel at it's base. I can feel no wobble or movement in the barrel with the pin in, other than the ability to rotate the barrel which makes no difference. The pin fits snuggly but is easily removed by pushing from the back of the pin and rotating the barrel slightly.
