Looking for advice on a handguard.

[bellavite1]

So I am building an AR pistol in 300BLK.
It will host a Griffin Optimus suppressor.
I've got me a 10.5", with a pistol lenghth gas tube.
Now I need to get me a free float handguard.
Ideally it would be a 10" lenghth, going partially over the suppressor.
Now, the suppressor's diameter is 1.375" and I am having a real hard time finding a handguard that will fit over it, moderately priced (<$100).
For whatever reason ID is not specified on most "budget" free float handguards.
Can anybody suggest something that will fit the bill?

More like the high $100's to low $200. MI has a few options available.

Chandlerhardwoods.com has some affordable hands guards, but I don't know about measurements. Worth a look.

Thanks guys.
Chandlerwoods was all out of stock.
I ended up with MI, playing it safe...
