 FOR SALE/TRADE:   Bushmaster 16” Dissipator Upper Complete with Charging handle and Bolt Carrier Group.  Dissipator or “DISSY” uppers are probably my favorite AR15 upper.  If you don’t know what a DISSY is?  The concept of the dissipator hinged on two positives:

A shorter barrel allows better maneuverability and weight savings A longer sight radius allows for better accuracy


Original designs were created simply by cutting down existing 20″ rifles down to 16″.  However, this led to reliability issues due to changes in the overall timing of the rifle.

Cutting down the extra four inches reduced the “dwell time” which is the amount of time the weapon maintains pressure so it can cycle.  You can think of it as the amount of time the bullet stays in the barrel after it passes the gas port.  See link!!


I just want to go in a different direction otherwise I’d keep it.  Barrell has Bushmaster rollmarks and "B MP 5.56 NATO" asking $325 OBO. Willing to trade for an AR15 Pistol Upper.  Meet in the Pensacola/Gulf Breeze area. All local laws apply. Email me directly at I check my email often but not messanger
