    Your DD will fire just fine with other mags. But the two types of mags that you are using other than the pmag are not very good and others on here have told you that several times and you just don't want to accept it. Also if you think your core15 is better than your DD then sell it and get something else but I can guarantee you that DD is one of the best AR'S you can own and core15 is nowhere close to a DD.

    I would call DD if it would make you feel better and see what they say. You might have to send your rifle back to them but they will take care of you if there is a problem.

    jdm: I wholly accept that fact that Pmags are better than the magazines I tried with my DD. I also am not in any way saying that DD is bad. I am just puzzled why these filthy magazines would work well enough in my Core and not in my DD. I know DD will take care of me, and that is one reason why im not too panicked. All I am asking is for some type of explanation. I accept the fact, as should anyone familiar with statistics or probability, that there many in fact be something wrong with 1 out of every X amount of guns that manufacturers like Colt, DD, Larue, etc make. This is a new rifle and I am only trying to make sure that what I have from DD is what makes everyone on this board and others appreciate them for the exemplary guns that they are. I will be taking this into the gunshop that I bought it from last weekend and just ask them to look over it (they give me a lifetime warranty as well), and i'll go from there. I might also put in a call to DD to see what they tell me.

    I can understand your frustration but I would call DD first and see what they say before you take it to your gun smith.

    Don't take an AR to a gunsmith. Unless it's ADCO.
    We miss you, AC.
    We miss you, ToddG.

    I'm assuming that the PMAG is new and came with your gun, while the other two are older mags? Looking at your pics, you might need to replace the springs in the tapco and GI mag. Also, since the buffer spring is stiffer (i.e. newer) in the DD the bolt action might be faster than the older mags are feeding. At least you know there is nothing wrong with your DD and the only issue is magazine related.

    Throw the other shit in the trash and forget about 'em.

    I only run NHMTG, Okay or Colt mags with Magpul followers or I use Pmags.
    THIS!

    I make sure I only issue good quality mags. Mainly NHMTG. I have a whole case of Bushmaster that we use for training only. Go get some good mags before you try anything else.

    One worked "well enough" the other had a failure in your CORE15 as well. As stated by others, try some quality mags. Mags can induce LOTS of problems. It could be the DD is built to higher standards and closer tolerances....maybe. Kind of like a AK will feed "anything" supposedly, which is not true b/c they have failures as well and FTF with bad mags as well. I will not bad mouth the two brands you are having issues with, but they are of lower quality and have induced many failures with MANY different AR brands. There is a reason why PMAGS are sought after and shipped to many troops overseas to use and why many instructors recommend them for a polymer mag.
    also, read up, most weapons in all platforms require a break-in period just like engines and other machined/manufactured metals. As well as quality lube for the break in period.
    Would you take a brand new car and drive it off the lot at 150mph with no engine oil or some cheap engine oil without fololwing a break-in period? would you put cheap contaminated fuel in the engine to see if it worked correctly? Would you put bald tires on a car and expect it to drive around a race track as well as tires of quality??

    Both the aluminum mag and the Tapco were brand new.

    I'd like to reiterate, that I do believe that Pmags are of superior quality to the Tapco and the aluminum mag.

    The reason I am a bit uncomfortable with the jams in my DD is the fact that these are new mags that work in other ARs. Again, so I don't get more of the same, they are probably not the best mags in the world...I get this. Someone made a car analogy, ill stick with this: Do I plan to put 89 octane fuel in a BMW....no, do I expect it work with 89 octane fuel if the need arises...yes. To get straight to the point. I expect my upper quality gun to work with anything I throw at it. You can't tell me that top tier AR manufacturers who (im assuming) have military use in mind, expect soldiers to turn their nose up at anything but Pmags.

    Also, why all the hate for gun smiths?

    Because 95% of all work on an AR can be done by the average joe with proper instruction. I liken it to letting someone else work on your computer - things can become counterproductive when you have multiple hands on the same problem.
