Hey guys. Just bought the classic A3 Collapsible stock to go on my PTR MP5 Clone. The unit fit nice a snug on the back of the rifle but when trying to get the locking pin back through the hole, the fit is very tight. To the point where I feel like I might scuff the pin or rifle trying get it through with a hammer or mallet.

Anyone else has an issue with this. Should I just tough it through? Or perhaps is there a smaller pin size for replacing the end cap with a stock.
 
I had the same problem with an SB brace on HK SP5. Tagging for updates.
 
#1 its a military rifle. So scuffing is ok. Have 6 MPs, got the gen 1 non F stocks, got the gen 2 non F stocks and got the F stocks. Can you post a couple pics here. They are meant to fit tight, the tighter in my experience the more solid the stock (I just got a new B&T mp5 telescopic stock - oh boy i am surprised how solid they are) ...

Post a pic showing the side view so can see the pin hole all the way through and a pic of the stock. Are you sure its german? A lot of non german stocks being sold out there.
 
If it's German is the stock drilled to mm instead of Imperial ?
