    Default Help identifying a part

    My LGS has a table/bin of random parts, spare magazines etc. About six months ago I bought this off the table thinking it would fit my PTR91.







    Where I’m confused is...

    The housing itself fits on my 91, and the dimensions seem correct for a 91 trigger pack, however, the trigger itself is too wide to physically fit through the slot and into the trigger guard.

    I know the TSR is likely Spanish, but I was under the impression CETME’s and G3 housings were interchangeable?

    It is definitely a CETME trigger housing.

    The CETME trigger is narrower than the HK trigger.

    You would have to find a semi auto CETME trigger pack for this to work on your PTR.

    The trigger packs are not interchangeable.
