The Fastback is a custom-machined CNC-profiled 'cocker body with our unique ultra light weight cocking block, designed from the ground up for the ultimate in fast E-Cockers. Not a conversion, the Fastback has one of the lightest reciprocating weights of any 'Cocker- we've pushed the prototype to 17 BPS (RaceGun frame, no bounce, without an eye!) with excellent consistency. Can it go faster? Damn straight! Videos coming soon!
The Fastback bodies come with a cocking block, Delrin bolt (black is standard, white or color-dyed available by request) with 'captive' pull-pin (just lift and slide- the fastest bolt removal too!) stainless pump rod (aluminum available by request, Titanium available by special order) and hammer.
Feeds are Angel-threaded, and the rest is 100% 2K-and-up 'Cocker compatible. Bodies are supplied "full size" to provide the largest internal valve chamber for LP use, though "mini-sizing" is also available by request
The Doc's Machine Fastback Autococker Body is older, so while it may be available used and in a few cases new, it is not commonly available anymore.

Ok I order the Gun. Comes in a little box very light. I pick it up its about the size of a hot dog bun or smaller and feels like im holding a peice of plastic very light. came with a nice twist lock feed neck (made by lapco) and the feedneck even had the fade annodizing continue on it. also had a nice reg receiver matching anno to body so it looks like on peice not like a chunk hanging off. The bolt was simple but had a somewhat small valve hole? I had the local body shop put it together asap. very fast gun, it is consistent and looks kinda like an ego and is very compact so small the loader hits my mask before the back of the gun. I get alot of attention when I use it. shoots just as accurate as any e cocker and has a very nice sliding sled to remove that clacky autococker sound. all you hear is pffftt pffftt pffftt pffftt pfffftt. I ordered from doc in late 2004. Took a week to come in and then I had the local shop put it together the guy there reccomended O rings be put on the bolt so I let him and then he basically overmilled the stock bolt and then the gun had major blowback so i ordered another bolt from turtleinnovations and modified it a little bit to fit my gun pullpin location and now it works sweet. Before getting the new bolt i tried to contact DOC from docsmachine (the maker of this gun)
he would not respond I wish i could have just ordered another bolt from him but nope... almost a year later I got a bolt somewhere else and made it work.
Great gun... in 2004 when I ordered it it was the only one of its kind but now there is many turtle conversion bodies out there to choose from and honestly dont buy from doc cus he will probly ignore you after he sends you it and makes a sale. I would have gave the gun a 10
but sorry docs service sucks so it gets a 7
