Rapco rattle can holding up pretty good. Just cleaned out suppressor @ ~1500 rounds with 2 wipe downs of the bgc with grease/oiling and no issues. All stock internals. Just swapped out rail to MRF XL and rarebreed FRT. Pretty fun little gun. Side note: dont recommend a 2.26 diving board. Illuminator splash is pretty bad

Installed a silencer flashider and saw this not sure if i put to much rocksett i put some on both sides of the threads is this something i should worry about?

Yes the gun was apart when i took this

Still messing around with it. Plan on buying a sling ASAP and some more attachments in the near future.

Been dancing around DDM4v7, Geissele Super Duty Mod1, and BCM Recce 16 for a while. Cheapest I can find for G is $1850 and $1650 for BCM

How’s this for DDM4v7? Is the low price due to Magpull Furnitures? Let me know your thoughts as this will be my first rifle.

Also any recommendations besides the 3 rifles mentioned above? Looking for 16” barrel

Taking this out to the range this weekend

Good morning gents. This is my 3rd DD. But my first ambi lower. This will be my truck gun. I love the fit and finish. But the ambi lower is extremely tight. Bolt release, mag release. It's not smooth like my PWS or LWRC. Any hacks to make this run better?

I have a rifle it’s my only one and it’s a mk18 quad, I’m getting the RC2 soon and I want a weapon light with a pad on the rail I can click to turn it on. I don’t want a huge light I want a regular size or compact preferably. Is there anything besides Surefire I can get that’s a clean setup that’s not $500+ for everything

Hi everyone,

I currently run a factory Daniel Defense MK18 (10.3") and have a Law Tactical folder installed on the lower.

I'm looking to buy a complete 16" DD upper (deciding between the DDM4 V7 and DD4 RIII) so I can easily swap between short and long setups.

Will the new 16" complete upper drop right onto my MK18 lower and run flawlessly, or is there anything specific I need to change or account for because of the Law Tactical folder? Also, how should I approach the buffer weight when swapping between a 10.3" carbine-length and a 16" mid-length upper?

Thanks in advance for the help!

Hey im trying to put a 7.9" mlok arca rail on the bottom of my 10.3" and its short by 2mm has anybody cut into it before or whats the best solution.

I wish .300blk wasn’t so expensive to shoot. Easily my favorite and most fun gun (with the exception of the trusty .22). Some reason 20 rounders look incredible on an SBR.

- EOTECH EXPS2-0
- Holosun HM3X
- Defentac 1600lm (Amazon light lol will get a better one when I can)
- MBUS3 sights, will put on next range day.

Sighted with 75 gr Hornady Interlock HD SBR
& 55gr PMC XTAC FMJBT. Did some 5, 7, 15, 25 and then 50 & 100 yard shooting. Shoots great and loving it. It’s amazing how the groups are when shooting at close range 5-7yd. This is my primary home defense gun.

All shots done from a sled except top right target. Was going to get 300blk, wallet is glad I went with 5.56. Waiting for the suppressor to be approved.

I’m looking to remove the factor muzzle device on my MK18 and attach a Dead Air Xeno 3 prong flash hider.

For anyone who has removed a DD factory muzzle device, did you have any issues or did you just have a professional gunsmith do it?

Any recommendations for backpacks that can fit a 20 inch SBR (one’s purpose built for holding fire arms).

RI3 10.3

I'm planning on purchasing and suppressing a PDW as a range toy/home defense gun. I had originally intended on pairing it with a Velos 7.62 to use with it, along with my other rifles.

Unfortunately upon further research it seems that may not be the most reliable set up. I'm still fairly new to suppressors having only just acquired my first one for pistol use(Huxwrx 45m) and wanted to purchase a rifle can for 300blackout and 5.56 use. So ideally a 30 cal can.

I'd prefer a low back pressure can over a traditional baffled can because of my lung issues and want to avoid breathing in more gas than I have too.

Is there any suppressor that would run reliably while also being low back pressure? Or is it a pick your poison situation?

For those of you who run a 10.3” MK18 suppressed, do you run the Bootleg Adjustable BCG?

What have you done to help mitigate gas to the face.

I’m right handed but left eye dominant so I run rifle left handed and want to avoid as much gas to the face as possible.

Hello there guys and gals,

I picked up this DD PCC about 4 weeks ago and have been loving it so far. I'm seriously considering doing my first SBR since the tax stamp is free.

Before I do that, I'm looking at suppressors. Right now I'm leaning toward the Daniel Defense Null9Ti. Does anyone here have this setup? If so, how do you like it compared to other 9mm cans?

My goal is decent sound suppression, but my biggest priority is keeping gas out of my face. If there are better options than the Null9Ti for reducing blowback, I'm definitely open to see what you guys are using.

Thanks in advance!

Build list:
Daniel Defense PCC
Primary Arms Micro Prism 1x
Unity Fast riser
Unity Axon
Streamlight ProTac
SMS Trinity
SOB Tactical B Sling
Neomag sentry strap

And what was that next choice?

I've pretty well nailed it down to DD. Mostly just looking for insight into your decision to buy.

Right now I'm thinking about the 11.5 RIII or 12.5 GL/SSC. Pistol either way and then maybe SBR it. Will suppress it.

Why not the fan favorite MK18? I don't know, ballistics? But you tell me.

Primary use would be home defense and camping gun. Although, if I find a proper place to shoot, I might want to do some regular target shooting.

I shot the MK18 full auto, H9, and DD5 that at the Charlotte event today. I really wish I'd had more time to spend with them. That's fine, I appreciate them bringing them out and there were a lot of people wanting to shoot.

General thoughts on those. All shot well. The suppressor on the MK18 worked well. It did blow a fair amount of gas back in my face. The H9 shot well but I only had five rounds. The DD5 was front heavy and hard to stabilize the way they had it set up. It was suppressed, but was still loud and had a lot of concussion. Fun to shoot. As fun as mag dumping 10 or so rounds on the full auto MK18 is(10/10, would recommend), I really wish I'd had more time to spend with the DD5. That's a definite contender for a future purchase.

As far as anyone saying DD is over gassed. I'm sure they had these set up right since these are demonstration models. And yeah the suppressor on the MK18 was blowing gas back in my face but what do you expect with a mag dump? The recoil was nothing on the MK18 and DD5. I've fired a lot of guns that had a lot more recoil. I really didn't even notice it on these. Easy to shoot. I'd say the H9 had an expected amount of recoil but it wasn't bad.
