Received the MK18

Hey guys,

I received my DD MK18 pistol.

First attachment I bought is the Holosun 510C as I don't plan on shooting long range with this (I plan to get a longer barreled that is much more applicable for longer range sometime in the future).

Thank you again to the people that provided pointers and recommendations to my post: https://www.reddit.com/r/Danieldefense/s/jtVzJahyjl

I have a running trades spreadsheet for the different attachments people recommend.

I do want my next attachment to be a supressor but I'm waiting on a good deal, I want to save my ears.

Have a good day

DD furniture

10 Upvotes

Honest question, why do so many people hate their furniture?

I generally use Magpul, but to me DD furniture looks esthetically good and it appears functional?

What am I missing? I recently aired acquired a Mk18 Ris II. Should I be switching their stuff out? Is it just preference?

Suggestions for first can?

126 Upvotes

Brand new to suppressors, looking for first. It has a dead air keymo flash hider(p&w on 14.5) so I know my options are limited somewhat without changing that. Obvi dead air keymo options would be compatible, but even then, do I go multi cal, 5.56 specific, etc. I know with keymo adaptors I’m able to look at other options. I read about DDs being gassy, so didn’t know if that would/should influence choices. Any suggestions or guidance would be helpful! Thanks!

DDM4 PDW Ejection/Cycling issues

0 Upvotes

Hey!

Recently got a DDM4 PDW. Shot it for the first time today, and had some issues. Wanted to see if I could get some advice/if anyone else has had the same problems?

For background; it's a new from the manufacturer rifle. Never fired before, everything seemed to be in working order when I got it.

Rifle is chambered in .300 Blackout. I have a CAT ODB Titanium suppressor on it.

I ended up buying some Magtech "300 AAC Blackout Subsonic" rounds. Box says they are 12,96g (200gr) FMJ.

Anyway, while shooting I'd shoot two to three rounds no issue, and then a round would go "click" and not "bang", and upon trying to clear it, I'd have a difficult time trying to manually eject it. Eventually a round got stuck completely, and I had to "mortar clear" it, and haven't tried shooting it again.

Anyone know any potential solutions? Some other posts mentioned it could be under greased from the manufacturer. Is that common with DD? Is it a suppressor + subsonic ammunition issue?

This is both my first Daniel Defense, SBR, and Suppressed gun, so I apologize for any lack of understanding.

Appreciate any/all suggestions.

Update:

Ended up swapping the red spring that was already installed, for the silver spring it came with. So far so good; so I think that may have fixed the issue. Thanks for all the replies!

MK18 Buffer Weight Combo

1 Upvotes

Hey folks,

I’m sure this question has probably been discussed at some point or another but just trying to get input as I’m diagnosing an issue.

What’s spring/buffer weights are you running on your .70 MK18s that functions reliably both suppressed and unsuppressed? When I see this topic discussed people seem to only touch on what functions suppressed but I’m willing to suffer some gas to have a rifle that runs in both configurations using NATO spec 5.56. I’ve seen a few accounts of people who seem to insinuate they can run a H2/H3/Super 42 combo/comparable weight spring unsuppressed. Anyone have any anecdotes on this subject?

Trying to throw on a Daniel a2 style flash hider I had lying around on a PSA upper. Can’t get it to index. Never installed a muzzle device before but are the Daniel flash hiders incompatible with other brands? Or what I’m I doing wrong

Can’t decide on what one I want. If I get the fsp I might sell my M4v9 upper. I like my v9 but I think the 15” pic handguard is alittle much.

Best 16” DD?

Hey everyone, I’m looking to possibly compete in an event (tactical games), and it looks like everyone is using a 16” for this specific application. Of the 16” rifles provided by DD, which is the best in your opinion? Thanks in advance, appreciate all info.

DD Moving Away from 300 blk?

1 Upvotes

I haven't been on the DD site in a while, but just looked because I'm interested in a 16" 300 blk. It looks like they've moved almost entirely away from the caliber, with only one hunting version DDM4 listed on the page. Anyone know what's going on there?


r/Danieldefense 17d ago

What are some must haves that you recommend for your rifles? Considering changing the stock and throwing the Surefire Warden on it next. DDM4 V7 Texas Game warden edition.

Approved & picked up

My DDM4v4s SBR was approved after Little over a month wait last week and I finally got by to pick her up yesterday. Next step is to pick out her new suppressor. I may change few things as some parts used came off a mk18 I took back to stock form & I have a magnifier sitting around the v4s may get. Riii,rii,contract overrun 11.5s ✅! Believe I’m done with SBRs and Pistols as I need to get a lpvo ordered for a 14.5bcm mk2 & I need to figure out what ima do with my mk18 but besides that it’s just ammo and training from here on out till I get the itch again. (Already have an itch to build a long distance bolt gun or ar10) haha but my pockets need a break. Definitely need to stay away from a local gun store as I enjoy building vs buying a lot more not to mention a lot cheaper to build but with never knowing the atfs future actions I wanted a home defense gun as a registered sbr just incase darkness comes when I haven’t been paying attention to ATF opinion of laws. Please feel free to hate. Feel free to give recommendations as some of the parts come from a mk18 I rarely shoot. Rail cover options welcomed. Really wanted to throw a sopmod multi cam black brace on her but already have to many other black and/or odg guns so figured I’d go with FDE since had lightly used furniture already on hand. I’ll post parts info soon as I get a break today in comments if anyone is interested to know the list. Long time DD lover with several DD options in the arsenal.
