DDM4 300S vs Seekins SBR8

[107driver]

I'm looking for a 300 SBR for fun out to 200 yards, the occasional class and match, and possibly home defense. In all cases I would plan on shooting it suppressed, a mix of subs and supers. I currently have a Dead Air Nomad-L and a TBAC Ultra-7, though the flow-through designs are intriguing.

I have had good experience with both Daniel Defense and Seekins, so I've focused on them, though open to others. As I see it the main differences are 10" vs 8", 1:8 vs 1:7, the stock, and of course the extended handguard on the Seekins--looks like the Nomad would just barely squeeze in. I'm not savvy enough to understand the implications of the adjustable gas block on the Seekins.

Considering both are DI guns from established houses, are there any factors that would push you to one over the other?

Thank you in advance.

Bump to see if anyone has experience with either of these — especially the Seekins.

What dontcha like about DD?

I don't have either, but I just dipped my toe into 300blk a couple months ago and researched way more than I should.

Both the DD and the Seekins will be pretty similar but here's what I see that sets them apart:

A) Adjustable gas block - having shot subs and super now, I can see where it's important to have some means of tuning the gas/recoil system. DD does this by including a separate buffer spring if you run subs, Seekins does it with the gas block. Either work, just up to you which method you like better.

B) Ambi controls - Seekins has an ambi bolt release, while the DD is old-school non-ambi. Again, up to you if that's important or not.

C) Handguard over supressor - the positives are more rail space with such a short barrel, the negatives are depending on the diameter of the supressor, it can really heat up your rail to the point you have to wear gloves or have some type of cover to hold onto it. Again, I don't have any experience with the Seekins, but something to be aware of.

Oh, also, just realized you're looking at the 10" DD. I'd check out the DD PDW in 300blk for a more equal comparison. I think that’s a 7" barrel.

DDM4® PDW (300 Blackout)

Compact and easy to transport, the DDM4 PDW is the kind of AR15 style pistol you can rely on for home and personal defense...plus it's a ton of fun to shoot. The 7 inch 300 Blackout Cold Hammer Forged barrel keeps subsonic loads subsonic and provides great ballistics for a shorter barrel. The...

I have neither the DD or the Seekins, however I do have an 8" 300blk with both an adjustable gas block and a tunable buffer spring setup. The gas block is substantially easier to adjust quickly, however you do need a tool. So plan to bring that along with you when you shoot if you plan on swapping between subs and supers. I would also argue that the gas block gives you a little bit more adjustability, but I'm saying that knowing nothing about how much adjustability the DD setup provides.

If you’re down with the Daniel and you can find one, it won’t let you down. Cycles everything right out the gate according to anything I’ve ever read about it.

What dontcha like about DD?

they supported universal background check till the uproar and then backed off. simply won't support companies that restrict my rights with plenty of other options that exceed the DD product

even in New Jermany, we had a whole department ditch their DD rifles and bought a 2a friendly company

just one mans' view is all

for the op, would go Seekins here

I have not shot the Seekins, I have shot the DD with no problems. I have a MK 18 from DD with more than 20k rounds and it has been a rock in terms of reliability. In my head, I always think of Seekins as chasing accuracy and I think of DD as more milspec and focused on reliability.

I use a Dead Air Sandman with my 300 Blackout. I am not sure if it works with the Nomad but I added the Dead Air E-Brake to the end of my can. It effectively makes the can like a quasi flow through and it noticeably reduces back pressure and gas to the face.

Just thought of one other difference: stocks and buffer systems.

The Seekins and DD PDW (7") use a "CQB" stock (Odin Works on the Seekins, Maxim Defense on the DD PDW). Those both use pistol length buffers/tubes and will be ~1.5"-2" shorter than the 10" DD when collapsed. Recoil impulse will be a bit harsher and it can be harder to find heavy pistol buffers if you need to adjust. Also, the metal cheek piece on both will slap your face like a jilted lover every time you shoot, so I'd suggest adding a foam pad if that's not something you're into.

The 10" DD uses a standard carbine-length buffer and tube, so you can put whatever stock/brace/buffer system you like on it after you make the ATF happy.

I would go Seekins all day. I have a Seekins sp10 and it’s a lazer. They also have great customer service.
I had a DD ar platform that I sold. From day one it was one issue after another. DD had very poor customer service as well, I was very disappointed. I will never buy a DD again based off my experience with the rifle itself, lack of features, all its issues, less that stellar accuracy, poor customer service, and a price tag that really demands a much higher level quality than delivered.
