Postby B to the RAD » Mon Sep 17, 2007 6:37 pm

this will be a 2 part guide.
Part 1: basic disassembly/reassembly
Part 2: work needed to make it an older style shotty.

Tools needed:
-medium Phillups screwdriver
-small phillups screwdriver
-medium standard screwdriver
-small standard screwdriver
-really small torx drive

Other Info
I will only be showing parts on one side of the gun but allmost everything is semetrical.
I dont have a shorty at this time but may add that to the guide later.

Here we gooooo.-Mario

Part 1:
Step one: remove the stock
Remove the butt plate and unscrew the bolt that was covered by it.
Image
Image

Step Two: remove the slide
unscrew the two bolts on the bottom of the slide.
Image
you will need to pry off one side of the slide it shouldnt be too hard but does require some force. Once you get the one side off there will be a small screw holding the other half of the slide on, remove it.
Image

Step Three:Remove the front end.
there are 4 small screws with lock washers on them that need to be removed.
Image
there are 2 screws holding this plastic piece on, remove them.
Image
Slide that piece forward.
Image
There are 4 more screws that need to be removed.
Image
now slide the entire front end off.
Image

Step Four: Remove the body.
start at the back and slowly pry it out and up off the internals.
Image
Image
watch out for this piece it likes to jump out and the little spring is hard to find.
Image
well done. lets move on.
I know there is another piece that is useally infront of where the shell goes but it came off this rifle my other one has it but that one is in a buddys car. I dont exactly know how this comes off but it came off this one pretty easy.

Step Five:remove the slide bars.
remove this piece and keep track of the spring.
Image
to remove these to bars rotate them down and out.
Image
it should now look like this.
Image

Step Six:lets take off that trigger guard.
there are 2 small screws holding on the trigger guard here.
Image
take them out.
Pull the trigger guard straight down.
Image

Step Seven:remove the barrels and hopup.
remove the 2 screws that hold this on.
Image
now slide it forward and slightly up to get over the little bump infront of it.
Image
You should have this now.
Image

Step Eight:take apart the internals.
there are 3 smal phillups screws,
Image
and 4 very small torx screws that need to come out.
Image
I dont have a Torx bit small enough for these so I use this broken standard bit.
Image

Step Nine:Seperate the two halves
use a small standard screwdriver to slowly seperate the two halves.
Image
untill you get this.

Step Ten:remove the internals.
But first I am going to go through what everything is.
Image
this is part of the feeding system it pushes the BB's into the hopup.
Image
this is what releases the BB's from the shell.
Image
This is your Tri-cylinder.
Image
This is your Tri-piston
Image
This holds the shells in the gun.
Image
this is the double spring and spring guide.
Image
this is your trigger assembly there are 3 parts.

OK lets start taking parts out.
first lets remove the spring's pull the spring guide up and back.
Image
Heres an exploded view of this part.
Image
next remove this part simply pull it straight out.
Image
next remove this, ceep track of the spring.
Image
Heres a view of the under side note how the spring goes.
Image
Now remove the shell holder just pull up.
Image
dont forget its spring.
Image
ok lets take out the pistons and cylinder, take the front end out firstand the pull up and out.
Image
this spring goes in this slot.
Image
this is what your triple piston looks like.
Image
This is what the nozels should look like if they dont look like this your in trouble.
Image
View from bottom.
Image
View from side.
Image
View from other side.
Image
View from front.

Ok last but not least the trigger assembly there are 3 pieces.
Image
see how the spring pushes this part up, the spring goes ontop of the peg on the end and under the one just in from there.
Image
this is where the top part pivots.
Image
In this hole and throught part 2.
Image
see how the trigger and part 2 have pegs that stick up,
Image
they fit in here on the first piece.
Image
now remove part 2.
Image
it looks like this.
Image
now remove the trigger, simply pull it straight up.
Image
note how the spring goes.
Image

and now you have a pile of parts.
Image

OK reassembly time.

Step ellevenreassemble the inards.
sart with the bottom half of the inside box.
Image
then add the trigger. See how the spring is on the top of that little tab.
Image
then install the second part of the rigger unit.
Image
Like so.
Image
now the third pice of the trigger unit. the sprin on the trigger goes over this tab,
Image
and under this tab.
Image

Step twelve
now lets put the rest of the inards back together, lets start with this pat of the feeding mechanism.
Image
this peg goes in this hole.
Image
and the spring catches this edge on the plastic.
Image
now the BB releaser
Image
the tabs on the side go in the slot here.
Image

Piston/cylinder asembly.
Image
this spring goes in this slot.
Image
You should be here now
Image
now the spring
Image
the tabs on the side of the spring guide go in these slots.
Image
now my least favorite part to install. the mag catch.
Image
it goes in this slot.
Image
now you are here.
Image
now join the 2 halves together.
Image
I layout the screws to my guns the way they are located on the gun.
Image
3 phillips
Image
and 4 torx
Image
the smallest 2 phillips go in these 2 holes.
Image
the longer phillips goes here.
Image
and the other torx go hereImage
and here
