It could work for you! - HERA Arms 110503 IRS AR15 Rifle Aluminum Handguard Black Hard Coat Anodized 12"

These rails are impeccably machined, very precise with crisp and intricate detail. The scalloped rail sections are a very nice touch and the length options are wide. I have purchased each length and they are all excellent final products. The profile is among the smallest of quad rail designs in terms of actual height, so they are quite svelte compared to a lot of traditional quad rail options out there while still providing expected room for gas block, etc., but you may need to do your research if you plan on a suppressor going inside the rail. They are actually the smallest quad rails I have found. The mounting system is very secure in my experience. The finish is superior to most, very professional and HERA ARMS markings are also very tight and unobtrusive. True, the QD points are basically useless for most QD connectors since they are within the scalloped rail keys, so I'm not sure why they're even there...but aluminum QD mounts in handguards generally don't hold up very well over time anyway, so you be the judge of what you need. Regardless, HERA has succeeded in making the blocky-ness of the quad rail concept into a more modern and slick, yet still very useful design.
