why in all holy hell do you use a wet lube in a sandy environment?
Because it works, and has worked for the past 10 years I've lived and shot in a sandy environment almost every weekend. It obviously worked in the video I made and it continues to work for me.
I fired 1,000 rounds a day for 5 days (5,000 total) in a row at the Tactical Response High Risk Contractor Shooting Package class hosted in AZ in June 2006. Temperatures were 115-120 degrees. We rolled around in the sand doing fire and maneuver drills, counter ambush drills, etc for 5 days. Many drills I fired 8-10 magazines in a period of 5 minutes. It did get too hot to hold the for end, fortunately I had a vertical grip at that time. We cleared our rifles after these drills to let them cool and avoid cook-offs.
My rifle had zero malfunctions, but I cleaned it every night and all the magazines every night.

(you’ll see me at 4:15 run back up and start dumping mags at the end)
See the sand in the air. We were on the range for 5 days in a row doing that for 12-16 hours a day. Sand got in everything. I am not saying this is equivalent to being deployed; only that this was a good test of AR15s in a desert environment. What this proved to me is my rifle will run in this environment if I maintain it and I can shoot at least 1,000 rounds a day, or about 3 times as much ammo as I can actually carry on me.
You will see a couple people in the video have problems with their guns. Some were using Wolf ammo and when they stopped shooting to move, the lacquer on the casings melted and stuck in the chamber. Others who did maintain their guns, did not clean their magazines as well and after several days of dropping them in the dirt the springs/followers were binding from sand.
I more commonly see malfunctions in guns that are run too dry.
