Background Reasons
to purchase an M60: Disaster: We put actual M-60 slings on both and mounted the side with an actual
M-60 bandoleer and string of dummy rounds which made both
look considerably better. We did
quite well with the sale of our surplus M-60 and our buyer
is delighted with the gun last we heard.
We would have loved to have 2 for the team but just
couldn’t justify it. Neither of us looks enough like Sylvester Stalone! About the TOP M60: Firing the M60 is quite fun, it has an impressive rate of fire and reasonable velocity. While the rate of fire is awesome, the velocity is slightly less than that of your average stock Tokyo Marui AEG (about 260 fps.) For this weapon to match its intimidating looks and justify its weight my dad and I decided when it jammed again to dump the dough that we made from selling the one M60 towards upgrading the other. The final decision was made when our M60 stopped firing. Either way I had to go into it. I had to unjam it once because my dad (genius that he is) thought, well instead of upgrading it, let’s just put .12 gram BB’s in it! That will give it a higher velocity and most likely the range. Since it was used in suppression role it wouldn’t need accuracy… WARNING! 12 Gram BBs should never be used in a TOP BB gun. It jammed BB’s from an inch into the barrel all the way to the loading mechanism. Just to unjam it, I essentially had to strip it half way down. The TOP barrel takes a “z” shaped turn so it’s not just a case of using a rod to unjam it. It was fixed for now and my confidence was boyed by the fact that I could take it apart and put it back together. The
next time it jammed the problem was more involved.
The loading mechanism wasn’t working.
I knew I’d have to open this gun up once again. At this, dad decided to invest in a full upgrade.
(Something I wanted to do all along!)
We purchased the Angs cylinder, Angs spring guide,
Angs 1 joule spring, and an entire gear set replacement for
the main gear system (If you didn’t know, there are two different
gear sets, one for controlling the spring and cylinder, the
other for the loading mechanism.)
The total cost in parts was about $240.00.
As I said it’s a complex design. Upgrading Important Advice: What
you need:
Taking
it Apart: Ok, now that that’s said and done, let’s get started. Obviously put it on safe, Unload
the gun and disconnect the battery.
You have to start off with removing the rear sight.
Do this by tightening the adjustment screw until a
bolt sticks out and it exposes a little hole.
Use your tiny hex wrench and unscrew that tiny thing.
Remove the nut and unscrew the adjustment screw using
a flathead screw driver on the opposite side.
Lift out the top portion of the sight.
Then remove the gold thing and the spring below it.
This will expose a screw, unscrew it.
Slide the rest of the sight out to the side.
Next comes the tray cover. Take
some tweezers and remove the horseshoe clips located on one
of the sides of the joint.
NOTE: Careful, these things fly and are nearly impossible
to find! Slide the
rod out from the joint. The
tray cover will now be free to remove. Next is the actual tray that holds the bb’s. Unscrew the four screws located on around the
golden barrel thingy. Also,
unscrew the screw that holds the springy thingy to the golden
barrel thingy (notice how technical my terms are.) Then lift
out the golden barrel thingy. Remove the last screw in the back of the tray
(located just in front of the hole that locks the tray in
place. Finally, remove the thing that holds the magazine
bag. Lift out the tray.
Now you have the bellows and spring exposed. Next you will remove the front half of the gun. Unscrew the 2 screws located under where the
site was on sides of the gun.
Then turn the Pig on its back and remove the rod located
on the bottom (made for use on a tripod.) This rod is also
held in place using horse shoe washers. This time you must remove both of them and once
again, be careful! Once
the rod is removed, two hex screws are revealed.
Unscrew them. Then
take a larger hex wrench and remove the hex screw located
just in front of the trigger. Now the front half of the gun is free to slide
off. Proceed to remove
the front half of the gun. The
bellows and spring will now be removed. Unscrew the bottom two screws located on the
bottom row of screws. Do
the same thing on the other side.
Now the bellows system and the spring portion will
lift out. Unscrew these
two screws on the portion you just lifted out. Now the two silver bars that stabilize the bellows
system are loose and will slide out.
The spring will come out with the spring guide as well
(careful, it can launch.) Now you must assemble and install the new spring and the cylinder that replaces the bellows. First you have to remove the front part of the bellows system, and use the back portion with the guides. Do this by removing the metal bar that holds the bellows in place and keeps the upper portion connected to the back. (Don’t think you can just cut the wide portion from the thin portion, you’ll see why after you take it apart.) Once you have this done, attach the piston to the piston head
and use the same bar that held the piston to the bellows system
together to hold the piston head to the piston.
Put on the rubber ring that came with the cylinder
set on the piston head and two on the cylinder itself. Add
the grease to the cylinder and it’s mechanism to ensure a
smooth action. Assembling this part is slightly different than disassembling
it. You won’t use the
silver bars used for the bellows system to hold it in place.
Instead, you will bolt the cylinder directly
to the frame. Be sure
to put the piston into the cylinder before you screw it in.
Also, use the screws that came with the new cylinder
and put them in the front two holes that hold the cylinder
in place. Next put in the new spring and the new spring
guide. Next you have a crossroads, if you are not planning on replacing the gears; you are done and can now reassemble the gun. If you plan on continuing and replacing the gears, you’ve got more to do! Your final thing to do is the most annoying. Start off by removing the stock. Unscrew the four screws located on both sides of the stock. Then remove the large screw in the back. The stock with slide off and expose the motor and fuse. Unscrew the cover with the loading mechanism and remove this
plastic cover. This
holds the second gear system that turns the loading mechanism.
Now remove the thin metallic piece that goes around the long
metal rod running from the motor to the gearbox.
Now that the gear box is totally exposed, unscrew the two
screws located in the back of the gear box. Unscrew the two
screws that hold the motor into place located in front of
the motor and on the left side of the gun.
Lift the motor out.
If you have a gear replacement set, you will replace
the long rod. (You
must keep the spring and the smaller gear that drives the
loading mechanism.) Next,
you must unscrew the large hex screw located behind the pistol
grip as well as the screw behind that.
Now, lift out the gearbox (careful of the spring for
the charging handle.) Remove
the screws that hold the gearbox together and open it in half.
Add grease appropriately (a light film) and insert
the gears into the correct place. I also thought it was best to keep the teeth
of the gear that pulls back the piston facing down. This puts the gears in the correct position.
If they are not like this then your gears will be set to pull
the piston back when it’s already back.
This could strip your gears (If you test fire it while
reassembling it, be sure that before you assemble the piston,
spring and cylinder portion that you have the teeth of the
thick gear facing down.) When putting the gear box back into
place, the wires must be put on the thin indent on the side
of the gearbox.
