It is a product of Bushmaster, orginally made for the Dept of Energy.
There is no room for the M4 bbl cut on a regular dissipator 16" bbl with rifle handguards!!!
Sure there is, its UNDER the handguards. Besides the CUT is the small issue, what people want is the slimmer profile of the M4 barrel saving alot of weight.
If you want to attach a M203 type flare launcher all you have to do is remove the lower handguard, the barrel is properly profiled fore to aft.
The only factory bushmaster "M4" bbl'ed dissipator upper I have seen is one offered by Kiesler and called the "Signature 16"
Who do you think made it for them. But that isn't a real Dissapator as it lacks the front sight.
