see above for example of Strip AMBI pack navy 3 Position. (0,1,F/A)

I know that I have to make a square cut out of F/A sear area. Is the dimensions different that SEF??
What are measurement in inch or Cm??

need info on ground off Hammer too??
Thanks

This is for the PTR 91K. (7.62x51)

I will pin the trigger navy 3 pos. housing, it clipped for S/A already.
Need all info to Keep the ATF happy too.

Thank from Rainy Oregon!

There is more to be done than just removing the auto sear. But all you need to do for that is cut the 90 degree chunk off the front of the pack where the pin is so that it can't be replaced.

You'll also need to drill and weld a small pin that stops the trigger from pulling back in to the FA position. Plus remove the trip lever ect ect. There is probably a lot more that needs to be done to use the pack legally, so hopefully one of the builders can chime in.
