I tried to find an answer before I posted this. I got a new DD M4 and would like to know if it should be stripped, cleaned, and lubed before firing? I read Colt adds a compound called Cosmoline (sp?
) and should be removed prior to first fire… How about the DD?
Always good to strip and lube a new firearm

I always strip and lube as well. No matter if its new or used. I also cleaned my DDm4v3 when I bought it new, as well as my colt.
Colt doesn’t ship ARs in Cosmoline. But yeah. I strip and lube. Patch the barrel til it’s somewhat clean and free of any lubes or other stuff.
My most recent DD rifle wasn’t cleaned before I took it out to the range. No issues with the few rounds of ammo I could find back in early April of 2013 that I could attribute to the rifle. I’d have no qualms about first doing a light amount of shooting with an out of box DD before wiping it down. However I don’t recommend trying to burn through 3K with the rifle the moment you leave the gun store, at least wipe down the BCG and throw some FireClean on it first.
Yep. You won’t hurt anything by shooting it. But lubing it is something I make sure is done no matter if the gun is new or 15,000 rounds old.
Thanks guys. I just got done with it. It was bone dry. They gave me a little tube of this Mil 25 lubricant so I used that. Pretty easy to do…I was surprised
yep… strip her down and generously apply lube.
wait. we were talking about rifles huh ?
oh well same method applies.
Perfect time to clean, lube, and check her over. Congratulations.
I would say 7 out of 10 guns that customers bring back after they purchase who have had problems are fixed by cleaning and lubing before firing. Its surprising how many get a blank stare when I ask if they have cleaned it yet.
Haha classic.
Exactly! 30 years of shooting and always the same.

I’ve seen this many times. Clean your weapon, if its your first AR you can get to know the in’s and out’s
I think Iraqgunz saw someone suffer this at Scottsdale Gun Club. Guy was getting malfs on a brand new, bone dry AR.
At the conclusion of our 10 round function test, our rifles receive a quick cleaning and light lubrication. I typically recommend that new rifles get field stripped, cleaned and generously lubricated. I recommend that the Bolt Carrier Group, Charging Handle, and Inside of the Upper receive an ample amount of lubrication. Keep the rifle well lubricated and allow the oil to condition the metal components. It’ll be slicker than turtle snot before you know it.
I endorse the same process. It needs to be dripping wet because the phosphate finish and anodized aluminum will wick up the lube pretty quickly and a normal amount of lube will soon end up appearing to be a little dry.

At my last gig before bouncing back OCONUS we got in 44 daniel defense MK18 clones (uppers). We applied SLIP 2000 to each of their bolt carrier groups and handed them to students who ran around 900 rounds per upper over 2 days. No issues.
Joe. Thanks for making a great rifle for one. Second, it’s the most fun I’ve had shooting a gun, ever.
Third, a quick question. What was that tacky substance on the trigger mechanism? I took it out to lubricate it to loosen the creep out of it a bit and noticed this tacky substance. It was exactly like the glue on the back of a post it note…
I just received a DD LPK and it is packaged great and the trigger group is pre-lubricated. DD is a class act!

No matter whom the Mfgr. is, I completely Detail Strip, Inspect, Clean, Lube and Re-Assemble before ever sending the First Round downrange.
