spyder imagine (the new blue one with out the shatty shight and other !#$% ups) twist lock neck, anti chop bolt, 4 prong electronic hopper, 12" spyder barrel with porting (this is not the stock barrel but it's like it but 12" instead of 9", has porting and is painted black)
Doesn't chop!!! wont shave down the inside of chamber or bolt!!!!!
Nothing yet might lower the vilocity just get a nitro tank
you MUST! buy this bolt inless you want the inside of your chamber scraped away because in the factory most of the bolts that they make arn't exactly round there more oval so they scrape the chamber at the top and bottom so dont use the stock bolt seriously for more then a few months. the first time i used this bolt i didn't chop any balls AT ALL!!! so when i went home to clean my gun there was no point because i didn't pop any balls in my chamber or my gun so this bolt is SUPER DANDY!!!
