-Affordability (100 bucks w/bottom line)
-Durability (All steel construction)
-Relatively good accuracy (Especially for an 8 inch barrel)
-Did I mention DURABILITY!!!!!
-Stock barrel needs to be replaced
-On the heavy side (All steel)
-Poor CO2 consumption (about 400 balls/9 oz.)
That's about it.
This was my first semi-auto marker. It lasted me an entire 18 months of constant use in less than ideal conditions. Rarely ever did it chop paint. With the velocity set to around 280, I found the range and accuracy comparable to that of a stock Model 98 and much better than Brass Eagle crap like the Raptor, which is in the same price range. An excellent gun if you like to send a lot of paint down range in a short amount of time and have it hit your target. After several dozen matches outdoors, and well over a hundred "kills", this marker finally quit on me. I must say, this marker outlasted just about every other marker on the block.
If you're looking for an excellent entry level marker, or an easily upgradable one, BUY ONE. It's cheap enough for just about anyone.
