First for those of you who don't know what cocker mods are called.
There are only really five types of mods to the body, but the combo of the mods is called a total differenct thing.
One -halfie/turtle, turtling is what you do when you cut the upper back part off of the gun off.
For you to do this you need to mod: Hammer, Pump Arm, Body, Bolt and Back Block.
You can as well do this to a spyder accept you only need the body and I think I will get into that later.
Two - Midgetizing, when midgetizing the gun there will a piece cut off of the lower back of the gun,
The body will be re taped. For you to do this you need to mod: Body, Pump Arm, Back Block and Bolt
Three - Mining, This is when the front of the gun is cut off and re taped.
For you to do this you need to mod: Body, Pump Arm and Actuating rod
Four - slot blocking, This is just like turtling only you cut a slot in the gun.
Fifth - Mid blocking, this is a mix of slot blocking and turtling
-----------Cocker lingo 101-------------
Halfblocked/halfy - you do both turtling and midgetizing
Micro cocker - you do all turtling, mining and midgetizing. This makes only hell of a speed ball gun and make it very light.
Orry - short for orracle (type of cocker)
Karni - short for kanivor (another type of cocker)
Now since you know what the mod is called I can tell you how to do the mod.
Why not start this off with a halfblocked cocker here’s more one works!
Here’s how to do it:

Do-it-Yourself Halfblocking Guide
---------- Parts your need --------
- Hacksaw (or a mill if you happen to have one sitting around

- Files (to make it nice and pretty)
- Micrometers (or a tape measure but micros are more accurate)
- Sharpie (depending on color you my need a metallic one)
- A good eye (or 2 if you have a friend)
- A dremel with a polishing bit and cutter
- A #10 – 32 TPI Die
- A drill with bit set.
Well this is a tricky one here cuz if you mess up just a lil bit you gun is ruined (I’ve been there till I got a mill

) but if your good and know your way around a hacksaw then this is the mod for you. You will start off by buying a BKO bolt (you could make your own but why) cut you back block in half so it looks like so:

Now mark the body where you want to cut, you know that lil hole for the hammer well cut about ¼” for the center on that hole(leaving a lil meat left so you can file it smooth)
Now you need to make a groove about 1” long in the top of the bottom tube so it will look like so

Cut the pump arm so it is about ½” past where you cut the body, thread the end of it with that #10 die. Drill a hole in the back block so there can be a pin for the bolt. Now take your hammer and cut it like so:
Reassemble and your done!

Do-it-Yourself Mini Conversion Guide
This is a very simple mod.
----Parts your need---
- Hacksaw
- File set
- #10 32 die
- 9/16" 24 tap (e-bay for that one)
Now this is for a 2k+ mining here for 99- I would ask some one on PBN for the tap size because I don't know. All you do on this one is cut 1 1/4" off the front of the gun then re tap with the 9/16" 24 tap. Cut 1 1/4" off of the pump arm and re tap with the #10 32 die. Cut 1 1/4" off the actuating rod and re tap with the #10 32 tap (note some guns use different size actuating rods so your best bet is to buy a mini actuating rod)
DONE! Put it all back together and your good.

Just as easy as mining only on the back not the front.
---Parts your need---
- Hacksaw-
- File set-
- #10 32 die-
- 3/4" 16 Tap (very very very hard to find but e-bay. or if your lucky you can just skip this if your gun has threads to the back frame screw)
- Wire cutters
Cut till flush with your frame (about 1") re tap but don't go to far or you will tap into the
hammers path and then your screwed. Cut about 1" off of your pump arm and re tap with the #10 32 die and cut about 1" off of you bolt to. Take your main spring and cut it slowy till you get the correct volcity and cut 1" off of your cocking rod and retap for #10-32.
Bam!
----------------------- EGO COCKER! -------------------
This is most likely the most expensive cocker mod you will come across, but that's only because of the parts needed. Some say this mod makes your cocker not a cocker any more but What the hell ill put it in here cuz it is a mod and I can do it on a cocker.
---Parts your need---
- EGO frame ($40 for 05)
- EGO trigger ($5-10)
- EGO board (I found a 06 for $20 but GL on that)
- Custom hammer (I used a BKO hammer and moded it)
- E1 noid and cover (just strait luck I found it for $20)
- EGO eyes ($15 -20)
- Drill, hacksaw and files
Total: about $200
I know I payed way less but it’s all in how you find them
Now that you have all of the parts you just need to mod the frame to fit the cocker.
Drill 2 holes in the frame one in the front and one in the back so that the ego frame will fit the cocker so the way I did mine is I drilled the back hole first so you have more room. Just rough fit the frame and mark where the holes need to go and then drill and counter sink the screws. Mark the hole for the front screw and drill it out DO NOT counter sink this one you don't have enough meat to drill in. Now that the frame fits great cut about 1" off the back for a nice clean look. Now just put in the board and hook up the eyes and noid. When putting the noid in the noid cover switch the LP lines going to the ram so when the noid clicks on the bolt will go forward and not back like a normal cocker would. Now as for the tricky part I moded a BKO hammer just because it’s an easy item to work with. Cut one side of the hammer till its just right and hits the valve pin at the right time. This will take some time to get right so please take your time with this its better to do 18 million cuts then cutting to much and screwing it up.
DONE!!!!! There is only one thing you have to remember with this you adjust the velocity by turning up or down the LPR. And PLEASE e-mail me with your custom stuff so I can know how many people read and do this mod and hell ill even post your gun with your name on it right here if you want.
