What is the torque spec on the barrel nut?
The PWS barrel nut design does not have a torque spec. Rather, it’s timed. This makes installation
easier and still
ensures a rock-solid lock-up.
What is the torque spec on the locking block screw?
The required torque is 20 inch/pounds. Excessive torque does not increase the strength of the system.
Why are there no anti-rotation tabs?
We did not feel external tabs were needed. The handguard itself locks into internal
anti-rotation tabs on the barrel
nut. The only way it will rotate enough to engage an anti-rotation tab would be for the
barrel nut to break loose. Which
is not a likely event given the torque applied to that and the integrated crush washer
feature designed into the barrel
nut.
Why did you move away from the BCM barrel nut?
The short answer is that we wanted to offer a new barrel nut design that facilitated a rapid
assembly/disassembly
because we know the guys buying our products are often wrenching on their guns.
Why are you moving away from the PWS barrel nut so fast?
Supply chain pressure has created an issue with a couple of the parts. It’s not insurmountable but it
would lead to an
unacceptable delay in supply chain integrity. As a company we are beating back delays at every turn.
Including this one.
What wrench should I use?
Part of the beauty here is that you can use any wrench you want as long as it spans the flats on the
barrel nuts. We
designed it so it would accept a variety of them.
Does the barrel nut have to be timed?
Absolutely. The timing/clocking is required to attain the correct amount of torque for the build. And
the included
timing/clocking tool makes it incredibly easy to achieve.
Are there any gas blocks this won’t work with?
We designed the COR to work with all low-profile gas blocks, both standard and adjustable.
That said, it is possible
there are larger profile blocks that are not compatible. But everything we have tested works
just fine. Everything from
Daniel Defense to Geissele to BCM to Aero.
What gas length systems will the COR work with?
The COR is compatible with all known DIRECT IMPINGEMENT gas systems. This includes pistol, carbine,
Mid and Rifle. As
well as a few newer gas lengths such as the Patrol length offered by Rosco Manufacturing. The COR
does not work with
Piston driven systems.
Which Torrent mount works best, considering the drop down rail?
This is completely dependent on your setup. What rail do you have? How long is your barrel? What
light do you have? Do
you have BUS? Do you have a laser? Are you using a remote switch? Where is that remote switch
relative to the position
of the light? There are more variables of course but it’s not that simple. Our Customer Service team
is happy to help
you work through all that. And we are in the process of giving you even more tools to help in that
process as well. Our
Customer Service team is always happy to help you decide which mount is right for you. Be sure to
email them at
Support@Clouddefensive.com and include a few
pictures of your current setup with detail on what your end goal is. This
will help them provide you the best advice possible with your purchase.
Will muzzle devices fit under the handguard?
A muzzle device will fit under the handguard. It’s not recommended to recess the muzzle device much
past the shoulder of
the barrel however. There is no benefit in doing so. And if you recess it too much, you will expose
your hands to the
danger of hot, fast-moving gasses. Don’t do that.
Will suppressors fit under the handguard?
No, suppressors will not fit under the handguard and truth be told, you don’t want them to. Integral
suppressors under
AR handguards transfer an obnoxious amount of heat to the handguards. The systems get hot enough
without that kind of
unintentional assistance.
Do the rails get too hot?
The rails get hot, just like every other handguard on the market. It correlates closely to the volume
of fire and
environmental conditions. The real question is “Do they get hotter than other normal handguards?”
The answer to that, is
not in any appreciable amount. Also, if that’s a concern, rail panels are perfect and we use them.
What is the height difference between the upper and lower pic rails?
The height difference between the standard picatinny rails and the recessed rail is 0.237 inches
Why is there only a partial picatinny rail deletion on the 12.95” and 15” rails?
As a general rule, the guys setting up 13.7”+ guns are not going to move their switching or even
their lasers all the
way to the end of that rail. If you do, ergonomics are lost. Remember, COR is designed in part to be
an ergonomic aid.
As a result, we maintained standard-spec picatinny rail height on the 12.95” and 15” rails. This
allows for BUS to be
mounted, which tends to be more common on the longer guns these days.
Where do I mount my BUS on the 9.55” and 10.70” rails?
Most people are in the anti-BUS camp on the short guns these days. Between reliability of red dots
and LPVOs, the
prevalence of offset red dots, the presence of lasers (a secondary or tertiary sighting method based
on setup) and the
realities of CQB; we don’t see the need to mount BUS on short guns. However, if you must do so, we
recommend mounting
the BUS on the elevated rail section behind the recessed portion of the COR. Your sight radius will
be reduced but still
exceed that of a pistol. And as a shooter you have 4 points of contact on the rifle compared to only
2 on a pistol. So
you still maintain more than enough mechanical capability for accuracy in that highly-unlikely
emergency.
What if my department mandates BUS on the gun?
Then you mount the BUS behind the rail sections on the 9.55” and 10.70” rails and you mount the BUS
on the forward rail
sections on the 12.95 and 13” guns.
Will you make a proprietary front BUIS?
We’ve toyed with the idea but we do not think we are going to do that at this time.
What colors are available?
Type III Black anodize, as well as offering Flat Dark Earth, OD Green, and Clear. All colors offered
are anodized.
Why did this project take so long?
A combination of manufacturing realities in the covid/post-covid era combined with Cloud’s rapid
growth and the
subsequent realities under our roof associated with that. It just didn’t happen as fast as we
wanted. But staying true
to who we are, we refused to cut this loose before it was ready.
Why did you delete the integrated QD mounts?
We didn’t like the notion of steel QD hardware plugging into our aluminum handguard. It’s easier and
more robust to just
use an existing QD mount on the MLOK slots. It’s also more customizable for sling mounting that way.
In the end, we
didn’t think it was needed.
How much do the rails weigh?
Full rail = barrel nut, all hardware and rail
9.55” = 11.1 ounces
10.70” = 11.8 ounces
12.95” = 13.6 ounces
15” = 14.7 ounces
