    Brand New DDM5V5 cycling issue

    I have a brand new DDM5V5 in 6.5 creedmoor.

    It will eject perfectly, the bolt cycles back home, and resets the trigger, but it won’t push a new round into the chamber.

    80 rounds down the pipe now, and I have to manually charge it ever time.

    This gun ships with an adjustable gas block. It has 2 settings, all the way to the right is for suppressed, all the way left for unsuppressed Californians.

    It was set to suppressed out of the box, wouldn’t eject.

    I changed it to the left position, unsuppressed, and as I described, it ejects, cycles, resets the trigger, but doesn’t chamber a new round.

    Brand new pmag gen 3, 20 round mags.

    I’m going to contact Daniel Defense on Monday, but I thought I’d check with you schmucks as well.

    What ammo? Maybe not enough oomph to fully cycle the bolt back?

      The bolt is cycling all the way back home and resetting the trigger. I just get a click and no bang because it didn’t grab a new round, but the bolt is fully in battery.

            Did you lube everything up well before shooting.

            Is the GB loose?

            How many rounds did you put through it?

            Could be a misaligned gas block. Anyway, have DD fix it, that's why you pay more for DD.
            sigpicC'mon man, shouldn't we ban Democracks from Cal-Guns? Or at least send them to re-education camps.

              It sounds like the gas pressure is low and not throwing the bolt back enough to strip a new round. I'd try hotter ammo for confirmation, or a different mag, but before messing with the gas or buffer system I'd have DD fix it. You shouldn't have to buy parts to make their new gun work.

              Edit: I forgot, ScottsBad mentioned lube. Did you clean and lube it before firing? Or at least lube it?

                I think you got the cali converted DDM5V5 in 6.5 creedmoor. You can now have a pistol grip and 20 round mag now since it’s a bolt action.

                All jokes aside, I think it’s under gassed.

                  Assuming it's all lubed up and you don't have a magazine issue... try below test to see if it's a gas issue.

                  Round in chamber, empty magazine, fire the round.. does the bolt lock back on last round? Try it 5 times, does it lock back all five times? If so, you don't have a gas issue. If it doesn't lock open on the empty mag, you have a gas issue.

                  If your adjustable gas only has two setting and you have it fully opened already in "unsuppressed", check your gas key to make sure it's not loose. If gas key is not loose and stalked corrected, check your buffer spring and buffer combo.... make sure it's correct for the type of stock you're using (A2 or carbine?)

                  Report back...

                    After your initial clean and lube you need to shoot NATO powered ammo for break in.
                    200-300 will do the trick.

                    Try another mag. GI spec aluminum known good mag borrowed from a shooting buddy.

                    Some Pmags will gag a new rifle prior to break in point.

                    NATO powered ammo. NOT 223 powered for break in.

                          if it locks back on an empty mag, there is enough gas.
                          you can't push the bolt back farther with more gas, lol. back is back.

                          but if the OAL is long on that ammo, it could be hitting the lands, and you are either pushing the bullet into the lands, or your pushing the bullet into the cartridge.

                          randy can tell you if he is here.

                            This is your problem. Buy a known good factory ammo with more oomph.

                            It will eject perfectly, the bolt cycles back home, and resets the trigger, but it won’t push a new round into the chamber.
                            What does this mean, cycles back home? Where is home? Does the bolt close? how can it cycle "home" and not chamber a round? Does it get stuck on the round at the mag or do you get a malfunction of some sort?

                            Could be either a mag problem or the bolt is not cycling fully to provide enough forward momentum to strip the round. Or it's OAL as mentioned previously and getting hung up in the mag. Can you describe the problem with more detail? I would start with anything else besides Freedom Munitons/LAX ammo, at least for break in.

                            ETA: If it feeds via manual charging that is in favor of underporwered ammo vs mag or OAL issue. Doesn't rule it out but gives it a little more weight.

                              OP, what is the OAL of the cartridge you are using? Sometimes “match” ammo is longer, and I believe your magazine is designed for 2.830" OAL maximum

                              If you have other 6.5cm cartridges and magazines, maybe from a friend whose rifle is cycling fine, you could try those before digging too deep in other places
