proline autoresponse trigger

[thegrayghost]

just got the proline trigger...when installing the trigger thru the rail, do you have to put that little pin in the assembly to lock into the rail, as i took out of the classic mag? the hole is there to slide the pin thru the assembly, but it doesnt line up to push down....so is the pin in or out of the proline? thankx in advance...

i answered my own question...found a video of a working proline trigger and watched the sear (from a top view) working on that sear pin.....so, yes, to my question, the pin has to be there....
