PAK9 Rear Rail Update and Improvement. Adding a 1 inch riser for the folding brace.

This is a follow up to the $15 PAK9 Rail video.
I finally got the FS1913 Folding Brace and installed it.
The issue was when the brace was folded it shortened the grip to the point where it was uncomfortable and potentially unsafe.
My cheap solution to this problem was to add a Monstrum 1 inch riser ($8.95 on Amazon https://amzn.to/2zXrbno ) to the rail which gives an extra inch of space for the front grip, allows access to the mag release, and adds an inch of stock length when shouldering.
