The M16 has been plagued with problems ever since nam its not a very reliable weapon to this day. We have lost many service members because of the M16's failure and i would like to see the numbers from nam to this day for sure its still one piece of crap. Everyone who has used it to this day know it too. No flame intended but it pisses me off when i think about the M16. I built/assembled 155mm howitzers for the US ARMY and I took it personal to do my job right because their lives depended on me doing my job right. I rebuilt lathes from ww2 that machined the breech boxes for the 155mm gun too years before i got the assembly job. I also built CNC lathes that manufactured the main rotor, turret bearing races, upper and lower for the M1 Abrams tank. Were talking a vertical turret lathe with a 108" chuck. For the last 17 years I worked for one of the top ten engineering groups in the country developing new products and life testing new products for reliability. We also tested lubricates too. While i may not have the so called battle field experience I sure do have the credentials to say what i use, what works in the application and stand behind it. I have used and tested moly in ever situation you could think of ever since the early 70's when my buddie at Dow Corning at the test lab gave me some to try where they developed it and after they tested it. They ran a new jeep with moly in the oil on a race track then took the oil pan off and made another lap with no oil then put the pan back on with oil and it had no noises or rattles or knocks. The motor never froze up. They used in over heating gear drives too and they ran cooler.
My personal experience with it is I added it to my 4x4 truck in the engine and standard trans and transfer case and differentials and i drove this truck and hammered it for 152k and when i sold it the still motor ran like new and the trannies had no wines either.
I rebuilt a tractor once and did up the motor with the moly paste. It had a crank with a solid round rod bearing that you needed to press it apart to check the bearing. I didn't take it apart but it happened to be spun and the oil hole was lined up when i checked it. There was no play in it when i checked it. It was a freak thing the bearing turned and the cylinder got no oil. I was on my third garden tilling when it sputtered. I finished it and took it home to do my garden. When it sputtered again I took it apart. The rings cooked and the piston and cylinder were ok. If it wasn't for the moly it would of cost me big bucks. This was a 800lb cast iron tractor with a tilling attachment. Its farm equipment. Moly is like having an insurance policy you don't know about till something goes wrong and its needed thats when you realize it works and how good it is.
So moly is for extreme pressure and wear situations also so why not for guns too? I am probably the first one ever to use it in a gun application too.
On another forum there was a guy complaining about wear on his op rod the bluing was wearing off to bare metal. The other guys on the site said it was the norm for the op rod to wear and it was acceptable. I chimed in and said that all wear is unacceptable and it can be prevented by using the right lube. I sent him a sample of moly and he reblued the op rod and took it out to test fire it after 200rds the op rod showed no sign of wear at all the new bluing was still present. Like i said in my very first brand new chinese sks inside the reciever the rails are still blued and there is no sign of wear at all yet. I put a little in the gas system too on the piston. Even if it looks dry after firing it, its still present in the small pores of the metal protecting against wear.
I took out my new saiga after I moly'ed it up and hammered it and I went home to clean it. I assembled it after wiping out the excess moly and later on we took it out to hammer it again. I remembered on the way home i forgot to moly it up again. I took apart the reciever and took out the bolt carrier and no wear was present at all the rails were still blued. Like i said its an insurance policy we have even when we screw up it saved my butt.
I'm not blowing out my pie hole here it works and i have proven it does many times. I would never suggest something i didn't test or try myself.
I say get him some moly and let him burnish it in and wipe it dry then add just a little a very thin coat will do or you could wipe it so there is a thin coat of moly left in the M16 then test fire it. If using moly could prevent the M16 from jamming and that would sure be an improvement to its track record. Since it doesn't attract dirt so in a sandy condition it should be good too.
I am not making fun of what anyone uses I'm spreading the word there is a lube out there that prevents wear, reduces all friction and prevents galling it doesn't attract dirt and stays were you put it. It stays wet even over long term storage too.
I have nothing to do with the manufacture of moly nor the sale of moly but i do have something against WEAR of any kind. My guns will never wear out because I plan on handing my guns down to the future generations of my family so they can enjoy them too what great, great grandpa started and left for them. In the years ahead who knows what surplups will available for them to buy if any so i'm thinking about them now ahead of time with the few that i have.
I use TS-70 moly at
www.ts-moly.com The gun will cycle faster and smoother it cuts the cycle time down so much its noticeable. You can see it if you really know your weapon. This can be a big factor when your life and your buddies lives are on the line they are depending on you too.
