Quality: The marker is extremely reliable and durable.
Cleaning: The forearm slides forward to allow you to squeegie the barrel without removing it from the marker.
Accuracy: the marker is pretty accurate with a decent aftermarket barrel. The marker has sights and they really work.
Cold Weather Operation: the marker always performed well in cold weather even with CO2.
Now for a few things that I don't like.
Lack Of Upgrades:There never were that many upgrades for the Prolite. It was hard to add anything other than an aftermarket barrel. The aftermarket bolts were junk and did little or nothing to help the performance. However, I did like the Air-Tipps aftermarket hammer. It was polished and lightened to reduce recoil.
Trigger Pull: The trigger pull was long and stiff on a stock Prolite. However, this is easily resolved by someone knowledgeable about Pro-Lites.
Effective Range: I found the range on the Prolite to be somewhat limited. They just don't seem to have the same effective range as some of the other markers of the same period.
Conclusion: There is no doubt that the Tippmann Prolite is a good reliable marker. However, it lacks the high rate of fire and assorted other improvements that more modern markers have. I would have no problem playing at a commercial field with a Prolite from time to time. However, it would mostly fill a place in my collection and serve as a loaner in this day and time.
