We just got our rifle back from Bushmaster after some custom work. YES.
This is now a very fine rifle. It is a fluted Dissapator with a free floated Hogue handguard.
We also got a new match trigger installed. Very clean break, indeed. The fluting really balanced this rifle. The upper and lower is a perfect fit. We could not be happier.
They charged less than I had expected for the customization, as they exchange some parts, and they tossed in a goodie that I did not expect. Thanks. I hoped they would be proud of this customization and I believe that is the case.
My advice is buy Bushmaster and DEAL WITH THEM DIRECT.
