Wondering the same thing about the barrel nut weight.  I see an earlier post said the 13.5" was 14 oz.  Does anyone know if that includes the barrel nut ?  That nut looks heavy.



I *think* that does not include the barrel nut.  I remember reading a weight of over a pound.  It is silly that manufacturers are unwilling to publish the specifications of the products they make.



Reading all the posts and held one at the store the other day but never saw this before 5/9/13. I hadn't seen one till it was on a STAG at the LGS. Sweetness.

Also you guys keep asking about weight and if the barrel nut is included in the figures. It doesn't seem relevant about a few oz.'s because 10 rounds of ammo and 30 are more than your questioning. Besides, once the mag is empty, it will be lighter....

The HG feels great and I'm definitely getting one for my Beowulf. Rock Solid and weight is minimal. More weight in ammo and barrel length. 3 Gun, go Carbon.

Does anyone have a photo of a 13.5" Diamondhead Handguard on a rifle-length system?  Thanks.

Really close to pulling the trigger on this rail (the 13.5 inch one)  has anyone established the exact weight?  Any tips, recommendations, thoughts, pros, cons, etc?  This'll be going on a 16 inch DMR build.

The nut is 3.2 oz and the 10.25" handguard is 12.8 oz.

1 LB total, plus any rail sections you add.

Their 3" (2.75") rail section with 2 screws is .6 oz.

Hey busky, do you have any pics if the 15" rail mounted to the upper yet? I am curious to see what the 16" barrel looks like with the 15" rail. I am assuming the top rail measurement is 15" and the bottom about 16.25". Is that about right?

It should cover a short low profile one. The standard midlength forearm is 9". A standard short  low profile gas block is ~1.5"...

I just did a check fit on the new Midwest Industries Billet Upper and it does not fit.  The two alignment tabs will not allow the forearm to sit properly against the upper because of the extra material in the uppers area.  When I get to assembling my next rifle I foresee having to file down those tabs down half way to fit around the angled Upper.  My thought is to align the upper rail and use an exacto knife to scribe a line to file them to.  Any thoughts concerns other than making the tabs so small that they are too week to properly act as anti-rotation tabs?
Link Posted: 7/8/2013 2:23:27 PM EDT
[#14]
The two clamp screws should hold well enough to keep the handguard from rotating during use.
Link Posted: 7/8/2013 11:42:58 PM EDT
[#15]
Well, I will have to modify my new hand guard.  I will be either trimming the tabs down or taking them off. I'm not going to just leave the tabs un-altered which will screw up the spacing of the rail to the upper's rail. Plus the lower bolts will not line up in the two channels of the barrel nut. Below are some photos. All in all I really like this hand guard. It fits well in my hand and all the attachment whole have been drilled and tapped so there is no need for a back plate that might contact the barrel. I might have to tell my wife that it won't fit on her gun and use it on mine.

That's going to turn out pretty nice. I think you can get away with filing the tabs down to fit.

Here's mine...it's a 13.5" on an 18" SPR barrel from WOA. Unfortunately, the screw holes in the rail do not line up with the grooves in the barrel nut so I cannot attach the rail. I called Diamondhead and they're sending me another barrel nut so hopefully that's the issue. If not, I have no idea...anyways, I've planned on putting a scope on this build from the beginning but man, it looks sweet with BUIS



edit: currently its attached to the barrel nut, but the nut is just loose on the threads...this is the only way it fits :( hopefully the new nut will fix it!

Top rail: 13.5"

I read about the problem with the allignment of the bolts and barrel nut in another thread.  I couldn't do a proper test fit with my tabs problem, but I did check to see if - wth the barrel nut removed from the upper and inserted into the hand guard flush like it should be when all attached to the upper - there was a ever so slight miss alignment.  workable, but non the less an issue.  I plan on filling down the edge if need be.  I still like how this Barrel nut and the hand guard mount.

Rifle length gas?

[the 10.25  should cover most mid length gas blocks. this is the 10.25  on a 16"  barrel with the MI (longer than most)  gas block. it just barely sticks out and the slant in the gas block makes it look good IMO. .625  block and barrel btw.

I'm still struggling on getting a handle on this thing from the photos.

For those of you who have it, exactly how flat is the bottom of them? I'm deliberating between this and the Seekings SPR3 handguard for my precision build. If the Diamondhead has a flat/wide enough bottom, then I'd like to go with it, as the small size and figer grooves look appealing.

Just finished by build yesterday.


I used SI-Defense Billet receivers and had to file on the anti-rotation tabs. I filed them down just enough to get them to fit. If I had to do it again, I would use a dremel, as the file removed some of the finish from the back of the rail. Not a big deal as I will probably paint the whole rifle anyways.

My issue is a forward sling mount. I definitely don't want to put a rail on the side as it looks terrible as shown in a previous post. I'm considering a bottom rail towards the front, I just don't want it to be too long. How does everyone else mount their sling?

Does your guys' gas tube flop around with this forearm? As in, inside the receiver.  Since there are no indexing teeth on the barrel nut the tube is just free floating in the upper. Trust me I know that the teeth on a standard barrel nut should not be touching the tube, however it does prevent excessive lateral movement. Currently with this forearm my tube moves in all directions and its so loose, i can hear it clang just by shaking the upper. It can be heard through the phone or feet away it has so much play. I have assembled hundreds of uppers over the years and I have never had this situation.  I believe this is causing malfunctions because after installing the forearm I have failure to feeds and failure to extracts.  I noticed atypical wear on the side of the tube so I believe I am correct in asserting the tube movement is causing the tube and carrier to misalign at random.  I have trouble shot everything else in this upper and the only part change from before, when it went from functional to non functional, was the forearm. Perhaps its simply the combination of this upper with forearm.

This was a concern of mine as well, as the gas tube does move around a bit. However there is not a lot of movement, and I have not had an issue resulting from it after about 400 rounds. The gas key closes on it just fine. You could maybe try shimming it, although you'd have to use shims that can take a lot of heat.

I measured the hole in the receiver where the tube goes through and it's .197 vs .168 on my colt upper, so the combo of an oversized hole and the loose tube was it. To test the theory I pulled off the forearm and replaced it with a std brl nut and went shooting... Back to 100%. Oh well.

It may be possible to make a thin sleeve around the gas tube stabilize it? Maybe aluminum foil? I imagine the gas tube gets pretty hot, is there an adhesive that will work at temperatures that high?

I know some have asked how to attach sling mount or stud to the VRS T w/o having to use / buy the rail sections.

10/32 threaded sling swivel stud is what's recommended by diamondhead.10-32x3/8.  Below is a link to where you can purchase them.
You can buy a 12 pack for 19.99 + $7.95 shipping on brownsnell, or buy singles from below link.

Sorry to revive an old-ish thread... but has anyone had success mounting this on an Adams Arms piston set up? I'm assuming the barrel nut is too long to work with the Adams piston rod spring, but wondered if anyone had a way around this issue? I've tried contacting Diamondhead about this, and no reply. Same in the Adams Arms "industy" section (which Adams seems to rarely comment).
Anyone? AA + VRS-T?

edit: never mind. I received an answer from Diamondhead stating non of their current FF tubes will work with an Adams Arms system due to the barrel nut (as I suspected).

When you guys put the nut on, are you timing it at all or just wrenching it on?

So the nut doesn't need to be squared (flat side on top)? It can be canted and still get the rail on?

Your welcome  

It's very easy to Install.   However, I did need to do some twistng and pushing to get it seated over the nut.   Which is good because it's not going anywhere.   And don't over tighten the 2 Allen heads.

The bottom is perfectly flat, but rounded just enough to cradle in your hand.   Everyone I have had look at this rail says it's the most comfortable and natural ergonomics they have seen.   Don't expect something really wide.
