I've had/ got several 'top end' springers and bought a Remmy Express in 22 with a synthetic stock earlier this year.
A revelation out of the box. It responds well to stripping, cleaning out, deburring and relubing. Once that is done it's as good as anything costing 2-3 times as much. The trigger blade can be replaced with a WH rekord trigger blade which gives the trigger unit an improved 2 stage feel.
I adore mine and have a lot of pleasure shooting it, very accurate and consistent. You can't go wrong! But be aware they go a bit hot, so be ready to make adjustments when necessary!
A lot of guys at my club now have these, one guy couldn't decide between 22 or 177, so he bought one of each..
UPDATE
just done a google, the tyrant does not have the same action as the express, it looks more gamo like, so my comments above are redundant as they apply to the express.
