One of the only quads i could find that worked - HERA Arms 110524 IRS AR10 Rifle Aluminum Handguard Black Hard Coat Anodized 15"

I’m building my first AR10 and finding compatible parts has been the biggest hassle. I really wanted a quad with no mlok and this was perfect super light but feels like great quality and the rails arnt sharp like the mlok mounting ones. Has a QD sling already built in. I used on my PSA10 Gen 3 and it does fit with a small height difference that my other rifles have so I don’t think I could get any closer around this price point or without sticking with the same brand. It’s a could a finger nail height since I don’t want to measure it out. Not enough to mess up front and rear sights.
