This is my first gun so i havent got anything else yet.
Stryker Str-1 and all stock parts except for CO2 tank. (20oz)
New hopper (a viewloader vlocity would be the best choice for this marker)
New barrel (suggested 12in instead of the stock 9in)
New bolt (you can find one at viewloaderparts.com)
Easy to clean
Blowback (Balls bust in hopper becasuse of the blowback)
Smaller than other markers
To start off, this is a pretty good gun for the money. The Starter kit is ok. It comes with the marker, grav feed marker, 9oz marker, a squeege, mask, 9in barrel. That total is about 100$. The balls break in cold weather (no suprise really) in the hopper, and it chops ALOT in cold weather. bolt is plastic, so a new bolt can be purchased at viewloaderparts.com. I also would get a new hopper because grav. feeds are OK for practice, but when u in a game, it can hurt you. i have only been playing for a year and i am only a beginner and this is an OK gun for me, only with upgrades will i use it in a actual game.
Good gun. Get it if u r a beginner and u just want a gun to mess around with.
