Instructions for the American Fighting Man In Iraq & Afghanistan

This list of weapons constitutes the bulk of American small arms in use overseas. For directions and inquiries regarding the use of Gunzilla CLP on heavy mortars, artillery, and other infantry or support weapons please email us at: info@TopDuckProducts.com and we will get back with you as soon as possible.

These directions reflect the difference in the capabilities and usage of Gunzilla CLP and the current issue CLP. Gunzilla can extend the number of rounds fired between maintenance however, do not fail to clean and lubricate with the same frequency you normally would. Simply because you can confidently put it off is no excuse for poor maintenance habits. Remember, do not apply anything to the weapon besides Gunzilla, standard CLP will attract and hold sand, dust and dirt, Gunzilla will not. Sand, dust and dirt can be blown off, or dusted away with a simple paintbrush while on patrol.

Instructions for Mortarmen


M16A2 / M16A4 Rifles & M4 Carbine:
  • The service rifle and service carbine should be broken down completely and the bolt and bolt carrier completely disassembled to the maximum allowable level. If M203 is attached see M203 below for instructions.
  • The interior of the weapon should be thoroughly soaked with Gunzilla, taking care to saturate the entire bolt assembly and its every component, the underside of the charging handle and the inside of the upper and lower receiver. Then set these parts aside.
  • Punch the bore with wet patches until they are removed clean, and then set aside leaving the bore wet.
  • Wipe down the entire buffer spring assembly including the tube and take special care to wipe down the buffer spring.
  • With a clean rag and cotton swabs (if available), wipe the Gunzilla off the interior of the weapon and dry off the bolt. Squirt Gunzilla on the gas rings and leave them wet. It is very important to leave the gas rings wet.
  • Reassemble the bolt. Then, saturate the bolt a second time, set aside.
  • Dry patch the barrel until patches come out clean and dry.
  • Leaving the interior of the bolt wet, wipe the exterior of the bolt dry and reassemble the entire weapon.
  • Wipe the entire exterior of the weapon with a Gunzilla soaked rag, and then wipe as dry as possible.
  • Perform a function check, the weapon is now ready for firing.
  • Every cleaning after this one will be much faster.


M249 Squad Automatic Weapon & M249 Para
  • The scaled-down components of the SAW mean it is much more delicate than its parent M240 series of weapons. Disassemble the weapon to the maximum allowable level.
  • The weapon should then be thoroughly soaked with Gunzilla, taking care to saturate:
    • The entire bolt assembly and its every component
    • Underside of the top cover, feed pawls and feedway

  • Perform a functions check, the weapon is now ready for firing.
  • It is recommended that you load cover closed.


M2 Heavy Barrel .50 cal:
  • Being a recoil operated system, the M2 is easy to maintain, however, the small nature of the components means special care must be taken to keep them in working order. Disassemble the weapon to the maximum allowable level.
  • Small parts such as the accelerator stop, sear, sear spring, and bolt stud, etc. should be thoroughly doused with Gunzilla and set aside to bleed into a rag. This will make them easier to reinstall and perform more efficiently.
  • The weapon should then be thoroughly soaked with Gunzilla, taking care to saturate:
    • The entire bolt assembly and its every component, with special emphasis on the recesses of the bolt, t-slot, barrel extension threads and trunion

  • Reassemble the receiver.
  • Wipe the barrels dry, and then dry patch them until patches come out clean and dry. Use an All-Purpose nylon brush on the threads and teeth, then wipe dry. Replace the barrels into their respective carrier or screw it into the barrel extension.
  • With the weapon fully assembled, lock the bolt to the rear spray Gunzilla onto the exposed rod portion of the drivespring rod. Also, leave a thin coating on the receiver sidewalls and the bottom, between the buffer assembly and barrel extension and between the bolt and barrel extension. A visibly wet coating on these parts will be sufficient.
  • Work the bolt several times.
  • Close top cover, perform functions check.
  • Wipe any excess Gunzilla off of the exterior of the weapon.
  • The weapon is now ready to fire.
  • It is recommended that you load cover closed and maintain Condition 3.


Mk-19 Mod 3, 40mm Grenade Launcher:
  • The larger components of the Mk-19 mean that greater care must be taken to inspect parts for defects and to lubricate adequately. Disassemble the weapon to the maximum allowable level.

Mortarmen Instructions for the M252 & M224
General Maintenance for Temperate & Hot Weather

While the current issue CLP is not approved for use on the mortar systems, however, its use in the field is still a fact of life. Gunzilla CLP can replace the toxic Rifle Bore Cleaner and Medium and Special Oils currently in service. Gunzilla can reduce carbon, embers and blast ring buildup in the cannon tube during firing and allow for heavier and longer fire-for-effect missions to be run. While we still recommend running the cleaning staff in between long fire missions, its need will be noticeably reduced. Gunzilla will also work on the new titanium cannon tubes soon coming into service.

First Time Maintenance
Should be conducted per unit SOP with the following exceptions:
The cannon tube, breechblock, firing pin and blast attenuator device should be thoroughly soaked with Gunzilla and left to sit for at least 20 minutes or a maximum allowable time.
Remove the firing pin, clean and wipe dry.
Using clean rags, wipe the barrel dry.
Reassemble the cannon tube with firing pin.
The use of Gunzilla on the exterior will prevent corrosion during storage; the exterior may be wiped dry if desired.
Clean the bipod and its legs with Gunzilla to maintain smooth operation.

Prefiring
Should be conducted per unit SOP substituting Gunzilla CLP for the lubricant.

During Firing
Should be conducted per unit SOP, however, the unique capabilities of Gunzilla CLP being taken into account.

Post Firing
With the cannon still warm or hot, disassemble per SOP and apply a generous amount of Gunzilla CLP.
Swab several times and allow to sit for several minutes.
Clean and lubricate the bipod.
Return to the cannon and wipe it dry.
A light coat on the bore of the cannon will continue to protect and displace remaining carbon and buildup until the next action.
