Got this marker and with almost no time firing it, played in a scenario in relatively cold and damp weather. 40 degrees and dipping close to freezing late in the day, the SP1 was consistent thoroughout the day. Out of the box, it chrono'd at 309 and brought it down to 290 with a small adjustment. Now that I think about it, should've taken it down below 280. We were using Red Legion field paint and I had absolutley no problems . Another guy with a Tippmann A5 chrono'd at 270 was breaking paint in the barrel constantly and his cyclone break put him out for a long cleanup. Weather, paint, operator? Don't know. Anyways... The light weight of th SP1 is incredible. Only after 4 hours in the scenario did the marker start feeling heavy. The SP1 stock and a remote is really light and easy to maneuver with. Rate of fire was plenty for woodsball and I shot burst only all day long. Test fired with an Empire Reloader but found that my Dye Rotor was better even though it was heavier. The feedneck was solid but would like a clamping with a little offset so that I won't need to buy a 45 degree offset rail for my sight. I didn't test battery life... maybe next time I'm out. Used Cheapy batteries and had no problems as reported by some. Changed out after goig through a box of paint.
The SP1 is a solid marker in the hands of a novice player and appears to work well in all weather conditions. no regrets in buying this marker
Conclusion:
I would buy this marker again if I had too. Solid and reliable. Will have to see how it works in February!!!
