Roboman Plunger Tube Compatibility Part - Caliburn (Threaded Rod)

Shipping calculated at checkout.



Replaces the Stock_Alt piece of the threaded rod version of the Caliburn to enable you to use the Roboman Caliburn Plunger Tube set.

Since the C4 has done away with the larger diameter PVC Pipe for the stock spacer, this piece is necessary in order to fit the smaller diameter rear spacer tube on older versions of the Caliburn.

Only includes printed part. No hardware is included.
