MG34 or Sterling style "cheese grater" Handguards for an AR?

[Bustercat]

The rock river mountain rifle Handguard looks perfect, wondering if anyone knows of any others that would fit this bill?

Also open to capsule shaped holes, rather than circles, provided they alternate and aren't aligned and are all the same size. No keyholes, honeycombs, or weird shapes. Going retro!

Thanks.

The Troy Alpha series has a similar look to it. Circles, rows slightly offset from one another.

Ignoring Troy’s hiring controversies, I recommend against the Troy handguards. Those circles have some real sharp edges such that their “squid grip” add ons are necessary. I have a set for the Ar308 dpms lo-pro that are sitting unused.

Radical makes a cheese grater set. The machining isn’t as refined as Troy but it turns out be quite comfortable.

thanks.
I love the rock river mountain one best, surprised such a simple design is not more common. But I think it only works with carbine length gas systems (which seem harder to find as nitrided pencils). Fightlite/Ares only sells 16" carbine length systems. Ive heard people use mid on their SCRs.
Will I really notice any difference in performance between carbine length and mid length on my SCR?

I also didn't like the Troy rail, and it was heavy. JP makes a nice rail in the same style. It has no top rail, though you can put rail segments on it if you need for a front sight. SLR Rifleworks Ion rails might also fit the bill, in mlok. It's square-ish holes not round but the ultralight versions are pretty uniform looking without any extra rails.

Cant help with the handguard but the scr works perfectly with a larue 16 inch mid with a larue gas block.

Thanks for the help!
Just got off the phone with rock ridge, their mountain Handguard is compatible with Midrange barrels, so I'm going with that, either with a Faxon or maybe even a criterion.
UPDATE: It isn't. the rail needs milling and more importantly, the holes on the guard are in the wrong place to access the gas block screws.
