I have worked on or shot many of these jems. A true G-3 is selective fire and if transferable will run around $6500 or more so I assume you are refering to the semi clone. All I have shot, of both types are accurate, reliably and destroy brass and throw it like a fast ball. If you do not want to reload for it this is not a problem. If you take the thing a part do not pop out the roller locks on the bolt or you will not get it back togther untill the locks are retracted. Hint, insert the bolt backwards into the reciever and give it a hard push and you are back in business.
