Wanted: CZ UB Bren 2 Handguard

Looking for the long European version of the Bren 2 carbine handguard as shown in the photo. I'd like to offer you up to $500 (based on condition) for it if you intend on upgrading yours to the HBI handguard. 

I do not care about the condition (as long as it's still functional) or stripped screws. Not interested in the American handguard with 5-sided M-Lok, thanks.
