My PTWS is acting up
 

i have a Gen 2 PTWS it worked fine up untill now

when i fire in semi automatic the first pull winds the motor then the next pull it fires , with a gear sound after it shoots.

when fired on automatic it fires fine but after you stop firing ther is a motor sound and you can hear the gear hit something.

i believe it has something to do with the sensor that stops the gear after you fire it. but i am a NOOB so i know nothing.

noob with a ptw???? hate you......:D
I'm scared to answer the question with such high priced merchandise on the line :D.

It could be a very simple fix. Open the gun up and remove the upper receiver, it will make it easier to work on.

Drive out the bolt stop latch pin, keeping care to not lose it or the spring underneath. Then, with some small needle-nosed pliers, pull up on the main board up front until the red sensors are exposed. Wipe them off with a Q-Tip or similar if they have any grease on them. Then put it all back together.

You can clean the sensor holes on the sector gear with a sewing needle to remove grease if it's there.

What you describe can also occur if you have removed the sector gear and re-installed it backwards (resulting in the sensors not be able to read it properly).

gee thanks mcguyver
