Requires channel liner - JCS Weapon Designs G19 Bonesaw Slide w/ RMR Cut

For those of you wondering, YES you need to purchase a channel liner for this slide. It does not come pre-installed.

I couldn't find any information online about this so I called JCS and they specifically told me that it was included. Slide arrived quickly, quality looks good...low and behold no channel liner inside. For wasting my time while I wait for a parts kit to come, you lose a star.

Haven't actually shot it yet.
