Folks need to understand that I don't just sell bolt heads anymore because they need to fit and time up properly to your bolt and gauge up properly once fitted to your bolt in your rifle. I know that many are convinced it's OK just to screw in a new one that's longer and head to the range. There's so much more to it than that if you want it done PROPERLY. Take Peter's advice and read all of the articles on CHS and fitting bolts and you'll get the general drift. My best to all this holiday weekend.

I carry Arrowmark Tool and Gauge military specification gauges from Australiabut with the exchange for the weak US dollar, they are expensive and most guys are too cheap to invest in them to check one or two rifles in their collections. They are the only military specification .303 gauges that I use other than a set of originals that stays on my bench. There are coin gauges and o-rings and all of that available too but I'll be honest and tell you that I don't have and never will have any experience with that stuff.
I'll throw in a shameless plug too and tell you that unlike all of these auction sellers, I don't ship rifles from my shop that are out of specification in the first place!
