Trigger Assembly Conversion From Full to Semi-Auto

[762x51]

Does anyone have instructions for converting a standard full auto trigger assembly to Semi-Auto.

Is there a ATF letter describing the modification out there?

Thanks

Real simple, weld a plate to limit forward movement of selector bar.

Place selector in the semi position, add plate or whatever (preferably welded in place).  The Semi groups on the A+B models all have the 3rd position, just blocked. Look at the semi group if you have one.   I just bought a parts kit for the group to have a M3 conversion done, so I need to weld stop plate in mine. I do have TIG and MIG abilities.

Hi UZI_SBR_AWC and thanks for the response.

I also understand that the rear mounting push pin's diameter is 9mm (0.354") for the semi auto and 8mm (0.315") for the full auto assembly.

Yes, the semi group uses a 9mm pin, and the SMG uses a 8mm pin. I think Lee at LRM can/ makes a sleeve so you do not have to open up the full auto housing holes.
