    Lack of lube??? Maybe...

    Dried up machining oils that cause a shellac like build up in the chamber that causes really high friction??? Absolutely!

    I seriously doubt it's a lube issue, most all manufactures even the shit ones have sufficient lubrication when new. But if the chamber has a hard grease bake...it ain't gonna eat, and it ain't gonna shit!

    Get a damn chamber brush, drench it with solvent and oil, and oscillate and rotate it about 20 times in the chamber...and I 100% guarantee its gonna eat and shit every round...over and over and over again.

    Now, there have been two incidents reported here on M4C where a DD bolt carrier has had a leaking carrier key. DD fixed them right up. A leaking carrier key will cause short stroking too.
    I was one of those people. They confirmed the gas key was leaking and the replaced the entire BCG for me. Now runs flawless: dry or lubed, match ammo or Wolf. I will say DD has the best customer service I've encountered in a long time. They said they would check it out and change out whatever was needed, barrel, BCG, etc -- until it worked correctly.

    Well after all this technical discussion, I want to jut get back to the basics.... and I gave this question for everyone here.

    A friend once gave me an advice wen it comes o picking out the right weapon when the shit hits the fan, he old me buy a weapon that you can always find ammo for, that would a 7.62, a .223/556, a 9MM. Plenty of ammo around the world and Mae sure that he weapon will eat whatever yo feed it.

    So here I am, looking for a weapon to live and die with, would a mi
    -spec DD4 be it , when all have is a wet sandy weapon w no lube and shit ammo to feed it,would you live and die by it....regardless of price, ego, fit or finish. Because it seems we are closer thn we think these day to that inevitable day.

    Man, ALWAYS clean your rifle before you fire it especially when new! Lube it well. It should be wet like a .50 cent whore...wait wut?! LOL, sorry but I found that comment funny.

    Clean and properly lube the weapon. Then shoot it with quality ammunition and not cheap commie ammo. If it still misbehaves then tell DD to figure out what the hell is wrong with your rifle.

The second issue is a round would get fed from the magazine after the previous round has been fired, but it would not go all the way into the chamber, it would be hung at about an 30 degree angle between the mag and the chamber. Another issue is after I finish a full magazine, the bolt would not remain open for the next magazine (that happen 50% of the time). I also had an issue where a round would load but the bolt doe not go all the way in and when I pull the trigger it would not fire and then I pull the charging handle thinking that scenario 1 happen and then around get jammed into the back of the round that is already chambered, very frustrating. I have never had anything like this ever happen on any AR ever, it seems too temperamental to be just a clean and Lube issue. The Rifle is brand new and it is dry when I took it apart, but unlike a dirty rifle that is dry, it not full of foul and residual that can cause something like this. I can see it not performing to it full potential but to to jam 40% of the time is crazy. I had to basically fire a round and recharge after every round for almost 2 Magazines at one time...I thought maybe break in but never ever seen this before.
    A lot of what is described here is short stroking, the cause of which is underpowered ammunition.

    Why wouldn't you lube a new firearm? No matter what shtf teotwawki situation you will find more lube/oil before you find ammo. What is the craze of running a firearm with little or no lube?

    DD will take care of you if you have a real problem. Hope everything works out for you.

    I as well notice this with my DDM4V1 when using the Russian brands but still functions with no problems though. Like a weaker impulse or cycling of the bcg.

    It's been a while since I've seen so much bad information spewed on M4C and not been shut down yet. Please stop.

    You took a new weapon, didn't clean it, didn't lube it and then fed it shit ammo. This is an ammo issue and user error. Clean your gun properly, including the chamber using a GI chamber brush. Apply lubrication. If you don't know how, use the search button. Then break it in with good mil spec ammo. 2-300 rounds should do it. This will help break in the gas ring / carrier. You will notice that cycling will smooth out considerably and at that point you should be able to use whatever ammo you want. However, you may still experience issues due to using cheap ammo. Guess what, it will still be an ammo issue. That's the sacrifice you make shooting cheap ammo. Deal with it and clean the gun more often. Drive on.

    ETA: If you're still having problems after cleaning and proper lubrication with mil spec ammo, contact Daniel Defense per forum rules.

I use 3 different ammo Wolf, silver bear and golden bear, 3 different magazines, Pmag, Colt aluminum mag, and brownelle mags. had the same issue on all the ammo and magazine. Really pissed me off. I shoot the same ammo out of my Double Star and LMT , never ever had an issue with any of the others and used a variety of Magazine across the thsoe other platforms never had issues, I fact on my Double star I never oiled or cleaned it for 2500 round and it still functioned flawlessly. Anyone else had similar issues with Daniel Defense? I bought it because of their reputation for being able to stand up to the extremes and quality, this is not the case in my opinion.
    You really, really need to clean & lube all newly purchased weapons. For an AR, lube the BCG generously. Just because you got away without lube in your Doublestar doesn't mean jack. You were, in fact, causing excessive wear and tear, and abusing your firearm. Consider yourself lucky it didn't blow up in your face(joke). You can get away with shooting a lot of rounds (I've taken mine up to 4K without cleaning but with generous lube), but not without lube. That tells us you don't now jack about running an AR effectively. There are several threads on proper lubing and cleaning. Don't trust hearsay about guns from friends and family. Do your homework, do some research and forget about what you heard or what you think you know about firearms. Keep treating your firearms like your lawn mower if you want to. Eventually, your method (firearms ignorance) will cost you through premature parts replacement and or a damaged gun, then you'll be back on here posting another thread boasting about how you abuse your guns and can't understand why it won't run...
