I'm putting on a new 300 barrel tomorrow, but would like to know if the 300 kit uses the two collars to help locate the barrel onto the cases? I hope not as predictably I've a trackday on Monday and don't have any with which to do the rebuild.

I noticed from Tyga's website the kit does appear to have the collars, but I don' t remember them being there when I took the barrel off a few weeks ago. Saying that, as most of you know my memory isn't the sharpest tool in the box. Andy, did you ever install them?

I could wrestle some old ones outta a spare 250 barrel I have, but I suspect the OEM 250 ones will need to be shortened to match the machined 300 barrels. Is this the case Matt?
