Ask them is this is for the OLD style NOT new handguards - and take have the round male ends that hook into the holes of the rail WITH the backer.  Essentially are the same as in the picture.  The point is that the pic may be OLD.

The photo is exactly correct on the Delton, but the words are wrong - quick attach are the newer kind that do not work - so you have to call and get the SKU.

The ones at amazon are MLOK and dead wrong.

No, they aren't MLok.  They're designed to allow for easily removable circle rails without having to remove the rail.  Somewhat like Mlok, but not MLok.  If the circles line up, can't imagine any reason why these wouldn't work.

For heat management, I think I’d choose the Bonesteel and add a good angled or vertical grip.
I’ve bought gear from both companies and never been disappointed.

I run the stock furniture with an aftermarket aluminum heat shield insert (sadly no longer available) and bolted on a pic rail on my bottom handguard to mount a Stark SE-5 Express grip. I’ve also tried a stubby vertical grip and that works well too.

I haven't tried it but read many accounts of using aluminum flashing from the hardware store or even soda cans to make a heat shield.  In a likely over-protective frame of mind, I wanted to preserve barrel life by allowing heat to dissipate instead of retained by a heat shield and drilled vent holes in the beaver barf handguard.  It still got too hot, so I bolted on an angled fore grip.  It works well, although I still prefer the ergonomics of the  original and have to make sure my thumb doesn't wander upwards.

Well, I just ordered the AFG-2 (and a T-shirt, while I was there :-) )
So now I need to find a mount that will work for the NEA lower. What exactly should I ask for if I call Del-ton?

I don't see why these QARS or Quick Attach Rail System wouldn't work, but I have not tried them myself.

Just call them and ask what the distance between the cooling circles needs to be and make sure it's what is on your rail.  I would suspect it is since the rail is also a  Troy/NEA.  If you click on the 5.4" section link you can view the installation pdf.

I think I'll try the QARS. Unfortunately, I won't be back at the house until the end of the month to try it. But I'll send an update then.
Thanks!

because it attaches like an Mlok - the old ones have a circle that fits the TRX rail with a BAR that has screw holes centered to the rail holes. Completely different systems.  See the pic of the long rail section in the link you sent.

As stated earlier -- it's intended to be an improved attachment system for the exact same rail that doesn't require you to remove the rail to install, and prob also lighter weight.  Unless they changed the dimensions or locations of the round holes, then it should work.  Troy still sells new rails with round holes and seem to indicate that these should work with all previous gen, so don't believe there's any reason it won't work.

The holes male (picatinny rail) and female (handguard/rail itself) mating provides the strength.  The clamping mechanism is merely to keep the rail on and in the event there's a perpendicular pull force on the rail, which would be unlikely.  Notice that it's always been just two screws no matter the rail size?  The threading junction between the screw and the backer is the weak point in this system, regardless of length or type of backer.  Even magpul Mlok rails are only 2 screws until 4+", 9+ slot rails. 
*And I'd have to double-check but I'm pretty sure the bar backers are aluminum and if these new similar to mlok backers are steel (magpul's mlok T nuts are steel), then they'd actually be stronger than the former bar at it's weakest point...

Try amazon with their easy returns if you're concerned.  But again, it should work best as I and others can tell.

Let us know if it works. If so, I'll order direct from Troy. I avoid Amazon when possible.

Thank you.  Please keep us posted.  If you got the 5", also curious if that'll install...

Ok guys, can confirm they fit. Not quite as slick as M-Lok, but they work. I got it on my 2nd try. After a couple of hours in the pub.

They stand up off the handguard just a bit, but they lock up real solid.  I'm happy with them.  This is the 3.2" section.

Thanks for the feedback!
Do you think a longer one would clear that end cap on the front? Looks close. 
I'm putting an AFG-2 foregrip on, but wondered if I could put a light in front of the grip.
