Where is that place at dude? Think they would charge same price for a dissy hbar? I want mine threaded bad. I just got it back from bushmaster today because the barrel indexing was off. The grouping was horrible and I had given up hope on it but when I got it back it zeroed right in with only 2 clicks windage. I stuck a cheap crappy leapers 4x20 ar15 scope on it and about 125 yards it grouped 3 shots under and inch...that was the only group I could get on the paper. The scope holds grouping well but it wouldn't hold adjustments for shit. Anyway, I don't know why the indexing being wrong would have made it group like shit...unless the barrel wasn't seated right. Anyway, the dissi has impressed me and I am very happy with it now...enough so to spend money on flash suppressors and other stuff :)
Thanks,
Wes
