The Eclipse S63 Extended Adapter is the answer for those already using the S63 tactical barrel system but want the option to add more length to their S63 barrel.

Designed specifically to work with the Eclipse S63 Barrel backs and PWR Inserts, the Extended Tactical Adapter replaces the existing S63 Tactical Adapter to create a longer system that works with the EMF100 in complete rail section form, as opposed to CQB. The adaptor has a 7/8-20 thread section that can can attach a wide variety of after-market muzzle brake accessories to create any tactically inspired load out the player desires.
