Handguard extension

[flyguy123]

Hi all,
Just bought a new upper for my ar15 and it has a 10" quad rail on it. So far happy but I see 4 screw holes on the end and I'm wondering if there's a way to get another 5" or so worth of rail on there. Seems like it should just bolt on and give me a 15" quad rail. Any ideas?

Who’s the manufacturer of the handguard? Got a pic of the 4 screws? Does it look like this?

That's the type. Not sure on the manufacturer. I don't see any markings on it.

I have never seen an "extension" for a handguard. Likely would just need to get another handguard. (And maybe gas block, depending on gas length/block type)

Those holes are for an end cap, like KS posted a pic of .

What you have is just an end cap that covers the hole on the end of your handguard. You can’t attach another HG to it to gain more length. Either work with what you’ve got or purchase a longer handguard.
