Still waiting for my new one, but my old one fits nice and tight, no rattle at all. If the new one fits as well as the old, then I don't expect that to change.
What is it in the bolt that is rattling exactly? Where do you intend on installing this spring?
P.S. Canadian Tactical is a Canadian retailer who carries the HSS line of after market parts. They want 65 dollars for the bolt shroud, and 110 for the oversized bolt knob and handle. Unfortunately they only take VISA and (FRAUD ALERT) as payment.
Flick, You've already nailed the bolt shroud. Do you think you would be able to do the bolt knob? I know I already mentioned the oversized bolt knob, but it would probably be the best thing ever if you wanted to tackle that one as well. I just wanted to reiterate my enthusiasm.
