I have a stamp in un a SBR Mini Draco Underfolder.  I already picked up a Romanian Underfolder assembly so basically I am looking for my options.


I understand that the mini draco has a virgin underfolder trunnion in the gun.  I have the flats from an old romanian underfolder trunnion.  Could I use them as a guide and drill the receiver and trunnion at the same time without removing the trunnion?  I installed a yugo under folding trunnion in my Arsenal USA receiver and just drilled out the sheetmetal, using the trunnion as a jig.

If I have to remove the virgin trunnion could I drill it when outside of the gun? Leave it in.

Would I just be better off buying an underfolder trunnion from Apex gun parts for 75 bucks and swap the trunnion?  Depends on how good your riveting skills are

If I have to remove the current trunnion, how much of a pain in the ass am I looking at pulling the old rivets? Grind flat, drill out.


I do have access to a machine shop. so tools aren't an issue, I would just like to know what all my options are.

I drilled my mini out for the underfolder. Use a press or better, a mill. Go slow, use lube. That's some tough metal and you may need more than one bit.

But it was easily done in an evening and works great. I had an underfold WASR that I used for a template and picked up the underfolder hardware and stock at a gun show for $20.

While the underfolder is not ideal for cheek weld, I like it for being incredibly compact and you can still use the weapon normally with the stock in the folded position. And since this is not a long distance shooter, the cheek weld is really not that important.
