wasting time cleaning the arms...

Who is the smart aleck who suggested kiwi-ing Rifle?
you know when i was in BMT, i was like the only person in the platoon who is against kiwi-ing rifle. I took the pains using oiled flannelette to get rid of rust/mud.
and my platoon would hate me for no listening instructions. ahah.
other stupid things PC/PS ask you to do to your rifle...
using bayonet to split handguard,
using pincers to scrape off mud from the SAR 21 lens.
running water to wash sar 21 without the protector lens covering your LAD.
the oiling thickly/thinly theory.
kiwi rifle sling.
SAF uses Androx 311 and Breakfree CLP for their rifles.
Breakfree CLP is actually one of the best rifle oils in USA (for personal use), and it has PTFE (teflon) content which doesn't matter whether you oil thickly/thinly.
the ones the oil dries, it leaves a layer of PTFE on the rifle. this acts as a good barrier against the elements.
and one 5-litre bottle is about S$80. And i can see companies finishing it in 2 weeks. -
Their ignorance leads to me and my crew having to see such results of stupidity day in day out at our Armament Coy.Originally posted by Ponders:Who is the smart aleck who suggested kiwi-ing Rifle?

going to permanently return my ar-15 soon, pop soon.
honestly speaking i love that rifle, never IA before esp in range though i didnt put much effort in cleaning the barrel of it. nvm that i didnt shoot well in the range or most or none of us in my platoon had any IAs but i am just glad this rifle served me well during my range and field camp.
nvm it's old, dont have the forward assist etc, honestly i just love the feel of it.
ok, i did have an incident of no feeding during range but taht's because i didnt load the mag properly (totally my fault)
man i took pride in stripping the rifle during this timed test during my sitest and i came out the fastest in my grp, beating them by almost 10secs.

1. Introduction: Without a doubt, the British SA-80 (L86A1 and L86A2) rifles have proven to be among the worst small arms ever developed. It is embarrassing that the SA-80 is a poor Royal Small Arms Factory (Enfield) derivative of ArmaLiteÂ’s own AR-180. During many attempts to improve the SA-80, Engineers of the United Kingdom and Germany have learned much about rifle maintenance that may be applied to other more reliable rifles like ArmaLites.
Any process that can keep the SA-80 operating is surely a good process. The purpose of this Technical Note is to present the lessons learned by the Armed Forces of both the United Kingdom concerning the SA-80 and U.S. Forces concerning the M16 family.
2. Firearm performance in adverse conditions: Firearms do not perform reliably when sand, dust, snow, or water are blown into the mechanism by wind, moving vehicles (helicopters!) or by muzzle blast. Local conditions and exposure to contaminants must dictate the extent of cleaning and the number of times that cleaning will need to be carried out during the day. It just takes more work to keep a firearm operating under extremely bad conditions.
3. Cleaning and lubrication in adverse conditions: U.S. Forces have followed a long tradition of leaving firearms dry of lubricant during desert operations under the belief that less sand adheres to a dry surface more than to a lubricated one. This tradition has been proven incorrect. The need for good lubrication even in the desert has been well established during desert training and peace keeping operation, during the Gulf conflict, and by trials in a variety of climatic conditions.
The U.S. Army Infantry School recently concluded a series of tests that concluded that the best single product for maintaining most firearms is Cleaner, Lubricant, and Preservative (CLP). CLP has been developed to cover a wide range of climatic conditions and has been developed to act as a cleaner, a lubricant and a preservative. Using other oils may cause reduced reliability.
The following should be cleaned and left dry for firing: Bore and chamber
Face of the bolt
Ammunition.
(Preserve rifle, including these surfaces, with CLP for storage. Wipe dry before firing. NEVER lubricate or clean ammunition with CLP or any other oily material.)
The following should be cleaned and left dry (desert) or lightly lubricated (other):
Exterior surfaces and sights
The contact and bearing surfaces of these parts should be generously lubricated:
Trigger mechanism
Pivot and takedown pins
Cam pin guide rail within the body (AR-180)
Guide rods and springs (AR-180)
All rubbing or contact surfaces of the following parts: carrier, cam pin, receiver, charging handle, operating springs, AR-10 or M15/M16 buffer, and AR-180 guide rods.
Breech bolt body and locking lugs
Moving/sliding surfaces of the bipod, if installed.
Most operators tend to put too little lubricant on the firearm. Most inspectors tend to criticize firearms that are properly lubricated. A properly lubricated firearm will have lubrication flowing away from the intended surfaces. Any surface that holds all the lubricant applied to it is probably not lubricated well enough.
Emergency lubrication: In an area where immediate lubrication is important and absolutely no better material is available, a bit of oil drawn from an engine is better than operating the firearm dry. A vehicle dip stick can serve as an awkward applicator. -
4. Clean often: Under extreme conditions of sand and dust, every opportunity should be taken to clean and re-lubricate the firearm during lulls in firing. In particular the gas affected parts, gas plug and cylinder, should be cleaned after firing around 330 rounds and the breech mechanism and recoil rods lubricated.
If possible, the solvent portion of the CLP should be allowed to evaporate before using the firearm, leaving behind a well lubricated surface. Ignore the “white glove” standard of cleanliness; proper application of CLP will leave a sort of grainy/oily looking surface that includes particles of PTFE (Teflon®) on the surface. CLP must be well shaken to thoroughly mix it before use, otherwise little lubrication will be left behind when the solvent evaporates.
In conditions of extreme cold, a lighter lubricant such as “PLS” should be used. PLS is a light oil similar to “3 in 1” oil.
5. Abrasives: A carbon-removing pad (like Scotchbrite) is mildly abrasive and must be used only on gas effected parts such as the L85 or AR-180 piston (the fixed piece that the gas cylinder slides over). It is seldom to be used on the AR-10 or M15 rifles. Its use on optical sights will quickly damage lens and remove paint from the sight body. Its use on the exterior of the firearm will remove the protective coating which will allow rapid corrosion. Abrasive cleaners should not be used in the bore at any time.
6. Lack of time: Under high-tempo operations there may not be enough time to strip the complete firearm at any one time. It is therefore permissible to unload the firearm and clean just the upper or lower receiver group, and then clean the other group at the next short opportunity.
7. Magazines are THE rifle component most prone to trouble. They are prone to the entry of sand and dust and should be protected by a plastic bag or other enclosure before use. They should be periodically stripped and cleaned when exposed to sand and dust. Particular attention should be paid to the follower and lightly lubricating the magazine shell surfaces that touch the follower or the bolt catch trip at the rear of the AR-10 follower.
Ammunition should be checked and dried and cleaned before reloading the magazines. In sandy/dusty conditions it is advisable to load magazines with less rounds than their maximum capacity. This reduces the load on the compressed magazine spring and allows space for sand and dust to collect in the bottom of the magazine.
8. Do not experiment with other oils and greases. Military personnel, especially, should not experiment with other lubricants (WD40, vehicle lubricating oils, etc) unless CLP or another military-grade cleaner or lubricant is not available. Many commercial products are poor lubricants and can interact badly with the lubricants already on the firearm if the first layer is not thoroughly removed. Graphite-bearing lubricants will damage aluminum partsÂ… do not use.
Try to avoid loading a rifle immediately after cleaning the chamber with CLP. Let the solvent portion of the CLP evaporate away for 30 minutes so that no trace of solvent remains to cause a chambered cartridge to corrode firmly into the chamber. (This is normally a problem seen only with firearms that are left loaded for long periods with cartridge cases in contact with solvent.)
9. Overheating: Care should be taken that allowed rates of fire are not exceeded; theyÂ’re generally a waste of ammunition anyway. As firearms heat up, it gets harder for the breech mechanism to extract the hot cartridge case because a hot case tends to stick to the chamber walls, and hard extraction or failures to extract can result. In addition, the risk of the rapid cook-off of a chambered round increases with heat.
10. Firearm Protection: Keep ejection opening covers closed and get into the habit of periodically checking to assure that the cover has not flipped open inadvertently. Muzzle covers will prevent sand and dust or other debris getting into the bore. (Middle Eastern desert sand is different from beach sand. It is as fine as talcum powder and can infiltrate down the rifle bore and pack around the bullet so tightly that the bullet cannot even begin to move when the rifle is fired. The result can be failure of the rifle breech and destruction of the rifle.) Use plastic rifle covers if available.
11. Serviceability of Cleaning kits: Cleaning kits aren’t just nice to have; they’re critical to the successful use of any firearm. The contents of cleaning kits should be periodically checked for serviceability. Brushes for the bore and chamber and for general purpose use, and carbon removing abrasive pads are all subject to wear and tear and should be exchanged once they become ineffective. Use only approved cleaning materials and tools. Do not invent “improved” tools such as smashed clothes hangers or dental picks to remove harmless materials like the carbon on the muzzle or at the bottom of the bolt carrier.
The correct chamber cleaning brush is exceedingly important for successful cleaning and rifle function. No owner of an AR-180, M15, or AR-10 should be without a good supply of them. -

Did they lose a contract? -
use singer oil best...oil one time can liao...rest of the range no need oil again....no smoke and IA somemore....
-
Yes.But Singer oil is quite rare these days.Originally posted by AE86tofu:use singer oil best...oil one time can liao...rest of the range no need oil again....no smoke and IA somemore....
And one more thing, make sure the CLP you use, dont have solidified blocks of oil/fat.
Armskotemen, keep the oil clean at all times, and make sure that its not exposed to the air as far as possible. -
anyone using SAW ?
it seems the bloody weapon is prone to IA-ing like nobody's biz. -
always see it come in large numbers for repair.Originally posted by bismarck:anyone using SAW ?

i thought its not that simple as push up ? for me its confinement or extra.Originally posted by powercat:at my time u clean your rifle or not u still do push up, so i always the a nap while others is digging the rifle. is only a few more push up why not take a nap.
