Kidd triggers are certainly some of the better ones. But, and I admit I am biased, I use Volquartsen. Never seen any sponsorship of matches from Kidd, but tons of it from Volquartsen. Tac-Sol makes decent barrels and also supports the sport. Beyer barrels are a tad better IMHO, and another sport supporter.

When it comes to stocks, you really need to figure out what you are doing for sights first. The variation between bore and sight line can be accommodated with stocks.
