AK magazine spacer

I'm guessing you're like me, having purchased a Cyma full metal AK-74 body only to discover a significant gap beneath the hop-up unit. This presents an issue if your hop-up mechanism can't be securely attached to the mechabox. When I reviewed the design, I created my own solution and made some adjustments after printing it. The part fits snugly into the mag hole and seems quite stiff. To assemble everything correctly, you'll need M3 nuts and bolts.
