Assuming your talking about the spacer that is used to go where the unit bolts together under the barrel, theres lots of things you could use. Go to the hardware store and look for a small sleeve to take its place. Or something similar. I know the part, and you should be able to find something to use in its place. Try home depot.

This is the long plastic piece that sits and bolts on between the ears of the front of the heatshield, and rests against the part where the barrel is attached to the mag tube. It keeps the heatshield from sliding forward. I work in a hardware store, we have nothing like it. It'll have to be fabricated.

They make a simple round spacer for 5 shot models that keeps you from over tightening the heatshield screws, but I need the one for an 8 shot model that holds the heatshield in place.
