With winter coming and it getting dark earlier my local 50ft smallbore group is shutting down for five months and I'm needing a rifle to get me though the winter. The club has loaners of 1960s CMP Anschutz match 64s that I have been using for the last little while. Is the 455 trainer suitable for smallbore, and is it worth it to upgrade it? I can get the rifle local for $340. I was looking at the 455 trainer with a boyds pro varmint/tacticool stock and inlet the bottom for an Anschutz style rail. The next challenge is what to do for sights. I know I can put most any rear sight on it with a riser, but what to do about the front globe? I've read about some DIY solutions, but I'm not a machinist and I don't have a trustworthy gunsmith in the area. I've read several forums for most of the week and solutions seem to be slim for the 455 front sight. Any insight from the community? Thanks One other newbie question. What's the practical difference in the 18 vs 22mm globes?
