TecomecComplete Vise Assembly Jolly Star K00200169 Replaces Oregon 511AX 526265

This is a great upgrade for your Oregon sharpener. This holds the chain much better. It fit my 410-120 just fine, with the included washer/bushing. Just be sure you don't lose the ball bearings for the detent, like I did (they're 3/16"). Assemble it with the aluminum pivot part upside down, then flip it over to install. It took the vendor two tries to send the right item, but both were shipped fast. I'm happy.
