For any of you guys who'd like a local barrel threading done, I spoke with Summit Ammo a little while ago and they're offering a barrel threading + FH (standard A2) for $60.

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
