The Hera Arms Slim IRS Key Mod is a modern designed AR-15 Handguard made from high-quality aluminum and is build to handle the hardest use and abuse of tactical and competitive shooting. The IRS Key Mod AR-15 Rail is CNC milled from aluminum alloy and hard coated anodized for added strength.
This forend features keymod attachment points at the 3:00, 6:00 & 9:00 position. So, if you want to just use a scope or if you need to mount every accessory in the AR world, there is plenty of attachment area for your needs.
The IRS comes with his own barrel nut where the Handguard is clamp mounted with 3 screws for additional strength. The anti-turn millings prevent turning even at the hardest use.

    Very nice product with. Looks extremely good on a new build. Also very lightweight. Only complaint is barrel nut is very hard to find a wrench that will fit.

    This is a great forend! It is durable and lighter than you would expect with that kind of durability! I wasn’t going to get this at first but Chris from the Sales team at CBC assured me it was going to be a no brainier once I got my hands on it. I have come to trust Chris and what he says about the products so I gave it a try! I was not disappointed!! I would recommend this to anyone who wants a solid well built and light product to use on their AR!

    Just an awesome looking piece of hardware that’s extremely functional. I would have paid more for it but got lucky and found it at cbc. Easy to mount … watch the vids on YouTube.

    You will not find higher quality products at lower prices. Value, Engineering, & Aesthetics are all inherent in CBC Industry Products.
    Compare, do your homework, and then give them a phone call!
