Looks great... nice paint job. Consider adding front ballast so that it will balance without the bipod. I have a weight that can screw into the front of the forend. You can also pour lead shot into the barrel channel.
The shorty has a great action that can easily swap out barrels like the CZ457. The rail is very good but there isn't a high cant version so that is limiting unless you can machine or use the Burris XTR sig rings. As a donor action and with a friendly barrel maker, I think this could make a great base for a fully custom build but I doubt any prefit will be available.
Alot of the function issues that plagued the A version seem to have been cured in the X version.
WRT to accuracy, the longer barreled versions shot better in the samples I tested. However, with the shorter barrel, adding a long tuner like the tuna can still allows for a great handling rifle.
Good luck
