I have at least 1 number 1 and at least 2 number 2's... A least..
1. Ruger's crummy bolt handle cut out in the stock of their M-77's. It's Cheap. It's fugly. It degrades a perfectly good rifle
2. Variable Powered scopes.. There, I said it and I'm happy.
Lack of high quality, fixed low power scopes, ie, Swaro, S&B, and Zeiss
2.a. Stainless Steel hunting rifles. Hunting rifles are supposed to be blued, with Walnut stocks..
At least at my house. YMMV
