Its a little lengthy but i have been working on this for a while. Thought i would pass it on.
Break Free C.L.P. PTFE based cleaner, lubricant and metal protector. Test Subject= Colt AR-15A2 Govt. Carb. 16” bbl 1-7”. Purchased in 1995. I have only used CLP on this rifle for cleaning and lubrication. 12,600 rounds of PMC, M855, XM193 and Black Hills 60gr Vmax and 69 gr OTM. There have been a total of 6 malfunctions in this rifle. 2 were associated with a long string of firing and no cleaning. At 6,000 rounds I conducted a test to see how well the Break free held up to friction and heat. I cleaned the rifle and lubed generously. After 450 rounds (15-30rnd mags) I had a failure to eject. The cartridge came out of the chamber but did not eject. Catching the round being fed it hung up. I simply removed the mag and cycled the action to clear the stoppage. Action and BCG were a little dry. I then removed the BCG and lubed all contact areas liberally with a couple spray squirts from a pump spray bottle. Rifle continued to function until a failure to extract at 650 rounds. This concluded my testing. All ammo was LC 855, all mags were Colt factory 30rnd. 2 other malfunctions in this rifle were associated with a bad after market GI mag. I later did a similar test but only after leaving the rifle lubed and in the truck for 2 weeks. Upon inspection I noticed the lube (oil) had all came to rest on the inside of the receiver. After firing as it was I was only able to get 300 rounds through the gun before I had a failure to go into battery. I cleared the stoppage and got 60 more rounds through before a FTE caused the 2nd stoppage. At this point the gun was fairly dry. This left me with the conclusion that though Break free was a great all around product there had to be something better or at least something that could augment the CLP lubricity short coming. For those who keep there duty weapons in vehicles or locked up lubricant longevity can be vital. At this point I was convinced it was a dirty chamber and not really associated with lubrication. I thought the gun just needed a good cleaning, chamber and bore wise. Machine Gunners Lube Synthetic Lubricant w/ Re-Micronized Moly in Colloidal Suspension My nephew, with the 1/3 of the USMC from 20002 to 2006 told me while relieving me of some 12 year old bourbon that when he was in Iraq there were units that had this great stuff they used on there M2 50’s and there MK19’s. He said it was great because it stayed put and held up really well to the heat from the weapons during sustained fire. He was convinced it had saved there arses many a time by keeping there equipment up and running. They were also using it on there M-16’s.. After some research i.e. more bourbon and some phone calls we found out it was called Machine Gunners Lube made by Tactical Springs LLC. So it started again. Another test. Test Subject= Armalite M-15A4 SPR 20” bbl. 1-9”, Purchased in 2009. Started using MGL at 700 rounds. Rifle uses Black Hills 60gr Vmax, 69 OTM and M855 exclusively. Rifle has 4,600 rounds through it. I conducted the same test as above for the Colt Carbine. Using LC M855 exclusively. I experienced no malfunctions in 750 rounds. I did not relube weapon. The following weekend I cleaned the barrel and chamber, relubed and put another 500 rounds through the gun. Since then I have only wiped down the interior and cleaned the barrel and relubed. I have noticed that when doing this there is a lot of dirty lube and gun is never dry. When left in the truck for weeks the lube stays put. Conclusion= CLP is a great jack of all trades. Machine Gunners Lube is a great heat load bearing lubricant that stays put. Together they leave nothing to want for my needs. |

While I have Machinegunners lube, I have yet to try it.
Thanks for the write up, but did you consider that the rifle length Armalite gas system vs the carbine length in your Colt could have changed the results? Wouldn't degreaseing the Colt and using MGL on it be the better comparison test? |
| I like MGL because it stays put for much longer than CLP. I've noticed that CLP will burn off within a couple hundred rounds, or run off within a week if in storage. I haven't shot enough ammo in one session to burn off a noticeable amount of MGL, and in storage it will stay in place for at least 1 or two months. |
| Possibly. This is far from scientific. The colt is also broke in better. Granted the 700 rounds for the armalite was broke in, in my opinion. The big advantage again is the MGL stays put. Though so does a thin film of PTFE for the break free it burns off quicker. Maybe when i get my 12" Larue Stealth i will try your approach. But for now i have solved my problem. |

You will never shoot enough to burn the MGL off in a semi auto weapon. In a Full auto weapon maybe. I can afford to blast 1000 rounds in 1 range trip and that wont do it. I wont try again.  Between my trigger finger going numb and my kids bitching about loading mags.

| Mobil-1 and Slip work well also. the machine gunners lube just seemed to be the best for both handling heat load and staying put. My dad used to use motor oil and transmission fluid on his M-1 garand, carbine and full auto M-1 Thompson. They worked but had to be reapplied. |

I use slip EWL (and TW25B on the carrier to receiver contact points) and they both seem to hold up. |
