I was thumbing thru Sportsmans Guide and on page 9 they are selling surplus G3 lower assemblies...with 3 position safety.  My question is, will that work on a PTR91, they are essentially the same rifle AND if it will work, will the rifle go bang, bang, bang, bang, bang until the trigger is released.  I don't dare say the "A" word. 

 

Just need simple yes/no answers. If it won't work, why.  No legal-ese.

Read the reviews on the page. "Thomas" says no

Thanks Moto...I didn't see the second page of reviews.  Good looking out!

I would just get one from hkparts.net

 

Ive used 2 of their metal SEF trigger housings on my old ptr91

The original steel trigger groups must be modified to work on a semiauto. You can buy already modified ones on Robertrtg.com.
