We’ve modified our Caliburn slightly from Captain Slug’s original to give you better performance. Significant changes include:

– Rambase modified for a tighter fit making for a better airseal

– Plunger and frontbutt modified to be K14 compatible

– Plunger o-ring slot widened for better plunger airseal

– Top railgasm modified to take barrel adapter for tighter barrels
