    odd thing is that PMC bronze .223 is actually weaker than wolf black box

    i use Wolf WPA military classic 62gr HP in my DD MK18 and have no troubles at all and thats with the VLTOR A5 stock

    That's odd. I've never shot any PMC Bronze, only x-tac and that stuff runs perfectly in my BCM 16" middy with everything from H to H3 buffers. With current prices, I'm tempted to give wolf a try but other than that I have no reason to buy anything other than 5.56 since all my ammo comes from brown santa.

    wow you guys are great....thanks for the response
    I did not buy the DD yet (waiting for tax refund) I never heard of a break in period w/ AR's as well, and but in regards to

    porider - the pmc or AE 223 round issue is something I saw in another thread on here (could not find it if my life depended on it, came up in a random google search) and on another forum....maybe arfcom (again came up in google search).

    Meth0d & mini sounds like you guys used 556 first, that might be the way to go, put a few 100 rounds down range then see what happens. I just hate to use a "see what happens method w/ a 1500 rifle, you know what i mean.

    Fidalgoman - i was highly considering Noveske, but that price tag is a little high, but as I have heard before, "buy once, cry once" so i may think about them again, besides it never hurts to have 2 AR's

    Eric - you said
    assuming proper buffer setup,
    again w/ this being a new world to me are you referring to the buffer spring in the stock? if so wouldn't DD have put the proper one in the rifle? or would a different buffer spring be needed to take the 223 and 556 round? again don't mean to sound stupid guys this world of AR's is all new to me..... thanks again for all your help, y'all great.

    Hey, we all have to start somewhere.

    I'm not talking about the spring, but the buffer; the rattly thing that goes inside the spring. As far as I know, the DDM4 will come with a USGI spring and an H buffer which will more than likely be fine for a variety of ammo. I personally don't like to deviate from USGI springs but different buffer/spring combinations can help an experienced shooter fine-tune their weapon. I wouldn't worry about changing buffers and springs at this point. When you get the rifle, take it out an shoot many different brands of ammo and see how it works.

    If you do a search here, there is lots of information on what buffer/spring setups people are running as well as the technical aspects of how those setups affect the weapon's function.

    thanks Eric, I'm not to worried about changing to much right off the cuff. however i will start some reading like you said about different combos. as of now I'm just going to pick up the one i decide on, some extra mags, and ammo. heck i was even think of just sticking w/ irons for a while (unless one heck of a deal came up on aimpoint, eotech or an acog)

    DD drills its gas ports smaller because it is for use with true military spec 5.56. This COULD cause problems with weaker ammo, but I personally haven't had a problem with any ammo.

    Some mfg's will sometimes drill the ports too big to allow more consistent results with weaker ammo. This can cause "overgassing" with true 5.56.

    GeorgiaBoy - by weaker ammo do you mean under 60grain?

    No functioning problems using Wolf/Tula and PMC .223 in my DD 16" midlength upper. Lower has a BCM receiver extension kit with H buffer.

    I used a DD barrel on my latest build, it cycles everything but my .223reloads. I loaded the rounds close to minimum charge, so now I know why they don't work. They do work in my other builds.

    I hd a hunch that the gas whole in the barrel was smaller but I wasn't sure. Thanks for the info guys.
