That would be a real popular modification I think!
Looking at the inside of the stock hand guard for my Sport there isn't any attachment points for a heat shield, but it looks like if you took a Dremel with a cutting disk you could cut a groove along bases of the six indexing pegs/sockets...
Then form an aluminum sheet to fit in the handguard with flanges on the edges that fit into the grooves like in this picture....
You may need to drill vent holes in the aluminum to help ventilate the barrel.

Wouldn't a standard handguard that already has a heat shield fit? There are probably bazillions of them sitting in people's drawers and closets (who have replaced them with magpuls, etc...)
The idea (for me anyway) would be that you could use the Sport handguard that came with it and not have it heat up as much as it does after a couple mags down the barrel. I replaced mine already, just wondering if I could do something with the (almost) useless thing.

They fit, but they are bigger around than the handguard on the Sport.

Sorry, no sheet aluminum in the garage so no prototypes.

It is kind of strange...One would think they would have just used the standard guards. They already have them and they are cheap.

S&W uses the tapered profile hand guards on all of their ARs. I haven't measure my OR guards vs. the Sport but I would bet the ware the same width. Most other manufacturers use the wider hand guards and I can't stand those. You can find take off, tapered handguards for sale all over the place for around $12 - $15.

I have the stock hand guard off my mp15a and it has a heat shield
fear the free
With a littel modifacation you could make these work.
Problem is,not all Sport handguards came with the inside heat shields. Mine didn't...

I wasn't aware of this BillyJack. I only had my handguards on my CMMG .22lr upper to compare with the Sport, and the Sport were definitely thinner. I assumed that the Sport were even thinner than the tapered profile ones.

The original hand guards that came with my Sport never had heat shields. But the Magpul set that I use today has shields built in. To be honest I never liked the tapered guards in the first place. Did not fit my hand right.

Get the Magpul hand guard, under 30 bucks and takes 5 minutes. Install and don't look back.
