– 250mm or 290mm barrel length
– 250mm barrel Includes additional dart gate
– 290mm barrel is for the V2 Unicorn with threaded barrel
– Barrel includes narrow section for pumpgrip to slide across. Not necessary, but makes the prime feel a little smoother
– XYL confirmed the 250mm barrel dart gate is NOT glued to the barrel, just difficult to remove. It is possible to remove and swap the barrel without removing the entire dart gate. We did it on the sample they sent us.
