Hey guys, Just built a pistol ar from a kit, but wanted to put my Fat Comp 2 on the end. However, the threaded part of the muzzle is recessed into the hand guard, and only a few threads are exposed. I'd like to keep this handguard, and wanted to ask if anyone knows where to find a threaded barrel extension with the same thread so that it will just extend the barrel by about half an in or 3/4 in. The handguard is really slim, so the Fat Comp diameter is the same as the HG. I'd like to have a slight extension so that I can fit the Fat Comp either flush or with a very small gap. Here's a few photos to show what's going on.
