JP GMR-15 Retainer Pin?

[BlackBuzzard]

I just pulled this gun out of the safe after almost 2 yrs and noticed there is no retaining pin holding the silent captured spring assembly in place.   Just an empty hole where it would go.   

 

Did it fall out somehow, or did this particular carbine in 9mm just not have one for some reason?    I cant remember.

That's not an error, it's normal for the  GMR-15.  My GMR 15 also doesn't have the buffer retainer plunger but does have the hole where one would go on an AR-15.   I guess JP doesn't think it's needed with the SCC assembly since the buffer weights and spring assembly are all one unit.

They don't come with a retainer but you can buy one if it bothers you.  I think it is a special JP design, I have one but never bothered to install it.

When you purchase a SCS system separate from a rifle, the instructions tell you to remove that pin.  Completely normal.
