Old semi but still good for begginers or recreation players.
It is really heavy compare to real rifles witch is good for military paintballers
U can use many home made upgrades and after market parts are also avilable with no problems(in US).
EXC-68 is a VM-68 with x.chamber and bottom line.I thing this version is better than basic VM because gun has better balance and even with really heavy x-chamber is more comfortable in hands than basic VM.
Design of this gun is inspirated in real guns and I thing I like it a bit ; )
Conclusion:
Good as starter gun or for recreation or military paintball.
