DD M4v11 300blk adj gas block help!!

[mattman215]

So I only shoot suppressed and I am striking out on finding an adjustable gas block that will fit undernesth my rail system.

I shoot mainly supers and yes it usually feeds fine but is very dirty and from times I get s ftf from an overpassed system.

I have the 15in slim rail from dd on a ddm4v11.

Does anyone have a adjustable gas block that they could fit on there Daniel defense rifle with the slim rail

And yes I understand you “don’t need one” on a 300blk but it sure shoots better with one.

I would think a superlative arms or slr would fit. They seem to be about the same size as any other low profile gas block.

What the ID of the handguard?

 

[mattman215]

This is from the website
Once I’m home I can post actual dimensions

 

[winniedonkey]

Yea get actual measurements. Learned a lesson once.

 

[mattman215]

Yup same here I already bought a slr andnitndoes not fit which isn’t the end of the world as I have a colt that needs one as well but man it’s frustrating.

 

[C_R_Slacker]

Really? Man that thing must be tiny. If you can't find a gas block that will fit, you might try an adjustable gas key from rubber city armory.

Don't try a Master of Arms titanium adj gas block. I just took my hand guard off and tried to put it on a build waiting on a suppressor (Recessed can in hand guard). If it was set screw, and not clamp on, it would have been fine I think. I may be curious about this one as well in about 1-2 months.

I personally may just try a heavier buffer and slightly heavier spring first though. Comes with an H, and already have an H2 and H3 with a white/blue Sprinco spring sitting in packaging in the spare parts draw.

 

[mattman215]

Ya last resort I will try s h2 or 3 but gas is the real way to go

 

[mattman215]

Anyone have a cheep h3 spring while I figure out a gas block.

 

[mattman215]

Here are some pictures.

You can see very little space from barely to handguard

 

[mattman215]

I’ve decided try a h3 buffer go from there

 

[loveha]

That's probably your best bet. Other option is a whole new nut and hand gaurd to fit your preferred block. I personally happen to like the slim profile though.
Let us know how the H3 goes. I'll probably pick up the JP SCS with weights and springs.

 

[mattman215]

Yup I agree that’s the problem I love the slim profile and the handguard. I’ll let you know it’s on order.

 

[mattman215]

No real difference with the h3 spring still cycles hard as it did before.

Have you looked into these?

For $50, i believe I'd try one instead of replacing a handguard you like.

Forgot about adjustable BCG.

Kind of pricey, and don't know much about them.
With some super quick research, looks like the bootleg is better. It's even cheaper which is nice.

 

[mattman215]

Ya I have heard mixed reliability reviews form those

Hello just an update guys if you have a DD SLIM RAIL SYSTEM The WOJTEK adjustable gas block will fit. I have one on now and it works great.
