I have the newer version which looks and most likely is better than the other. This gun rocks! it has okay accuracy even with the stock barrel and has awesome trigger pull! To me the gun really isnt all that heavy becasue i have a remote but i love this gun. Plus the fact it can take spyder barrels is great. It is a very durable and reliable gun to get. I reccomend this gun to anyone. And the rear cocking is great. I shot about 1000 or more rounds in it the other day and not 1 ball break! This is a very good gun!
The only bad thing is the stupid case. They try to make it so that all the bruzier guns can fit in it, ya right u gotta almost sit on the stupid thing to close it. The bottom line out of the regulator comes out of the side but if you are right handed then you have no prob. But other than that this is a great gun!
