Things I liked:I was never a fan of airsoft until now. After I placed two drops of Gamo airgun oil in the mag and the inside of the mag reservoir I was asstounded. It has easily become my favorite airgun for plinking etc. Though there are no sites the weapon has supreme accuracey. Things I would have changed:Nothing. What others should know:I have already fired about 2000 rounds from this gun and it seems to keep on getting better. I only made one modification and that is I removed the heat shield it became lose and rattled quite often now I am in complete stealth mode.
