Awesome entry level marker! Shoots great, accuracy is amasing, easy to hold and operate. Very quiet and efficient gun if well-tuned! Centred feedneck location makes sights useless but is beneficial for players using standard hoppers without force feed systems.
Nevertheless, nothing is ideal. Some of these guns are NOT ready to shoot right out of the box! Actually, my SP1 had soft o-rings in the regulator that lead to air leaks. DYE o-rings brought it back to life.
Trigger setup is extremely important! Very sensitive trigger may make your marker shoot without trigger pulls and overtightened grip cover screws may block the trigger at all.
Circuit board has a very complicated setting system. To change modes one has to unplug the 9V battery, pull and hold the trigger, and then plug the battery back.
Note: Using the Lapco barrel adaptor may be difficult with this marker. Removing the o-ring from the adaptor solves this problem.

I love this gun. No problems at all. Almost the same thing as the GOG G1. I got about 800 shots off a filled 68/4500 tank. If you need any spare parts just get the GOG G1 parts.Way better than rental guns. Great for woodsball.Lube the asa first before putting on the tank.

Missing barrel o-ring

Awesome deal. However, two of my friends and I got these and all of them were missing the O-ring on the barrel that keeps it from rattling off. This is easily fixed by buying a spare GOG o-ring kit.
Also it comes with a 14" barrel instead of the short barrel in the picture.

Excellent!
