I know this is probably old, but I just found it. It seems pretty legitimate.

FINAL RESULTS IN ON TORTURE TEST-COLT M4 vs LMT M4
--------------------------------------------------------------------------------
Ok guys! I know that some of you have been waiting for the final verdict on my torture testing of the Colt M4 vs LMT M4. It should be noted that both rifles were run "wet" with Slip 2000 lubricant. Both rifles were well lubricated before each testing phase and fired without lubrication throughout each test. Here are the compiled results below:
70 ft drop down to concrete- 250 rds:
Both rifles were dropped from 70ft rappelling tower down to concrete with a loaded Magpul P Mag. Results: Both rifles fired 250 rds each in semi& full auto without a hick up or breakage of parts.
100 ft helo drop down to concrete- 250 rds:
Both rifles were dropped 100 ft from one of our helicopters down to concrete with a loaded Magpul P Mag. Results: Both rifles fired 250 rds each in semi & full auto without a hick up or breakage of parts.
50 ft alt water submersion test- 250 rds:
Both rifles submerged down 50 ft in salt water with loaded Magpul P Mag. This was done in an open ocean scuba dive 10 nautical miles out in Miami, Fl. I called my buddy at USCG & he took my team member and I out in one of their rigid hulls. Both my team mate and I emerged out of the water & immediately fired 250 rds out of each rifle in semi & full auto while staying afloat while my buddy on the vessel handed us the loaded P Mags. Results: Both rifles fired the 250 rds a piece without a hick up.
2 ft submersion in mud for 3 hours- 250 rds:
Both rifles were submerged in 2ft of mud and left in the mud for 3 hours with a loaded Magpul P Mag. Both rilfes were pulled out and were fired without cleaning. Results: The Colt fired about 125 rds in semi and it jammed once after a 30 rd full mag in full auto. A forward assist strike fixed the problem. Fired the remainder of the 125 rds in full auto without a hick up.
The LMT fired 125 rds in semi and 125 rds in full auto without a hick up.
500 rd simulated sand storm testing: (god this was messy, still pulling sand grains out of my a--)
Both rifles were loaded with Magpul P Mags & fired in semi & full auto while sand was blown from an industrial blower fan onto the the rifles while 2 operators fired the weapons. Results for Colt: The Colt jammed 3 times after 200 rds in semi-auto. With the first & second malfunction, the rifle got back in the game with 2 strikes to the forward assist & continued. Then, the 3rd malfunction was a failure to extract. P Mag was pulled, charging handle charged with ejection port facing down to let gravity work for us. The Colt continued to fire 250 rds in full auto without a hick up.
Results for LMT: The LMT jammed once with only 3 rds to go to complete the first 250 rds in semi-auto. A strike to the forward assist got the ball rolling and never malfunctioned again. Then, it fired 250 rds in full auto without a malfunction.
It looks like the LMT beat the Colt in the mud. It never missed a beat. It also beat the Colt in the simulated sand storm. The LMT malfunctioned only once in semi auto. Again, I personally attribute this to the enhanced design of the LMT bolt. Their bolt clearly runs smoother & cooler. One more thing that this test has proven (something that I and other experienced folks have said many times), is that the M4 doesn't need to be kept meticulously clean. Yes, clean it if you have the down time. But, it has to be run wet. Lubricate, lubricate, lubricate! There you go gentleman, time to spend that tax rebate and pray that that damn terrorist doesn't get in our White House!
