It's a body cover for an FN series of rifles. I think it's the mount for the UK Suit sight without the sight of course...

Thanks appreciate the help. Does it have any value? It was in a bunch of carbine parts I bought in an auction.

Not unless you need one. Here's some for sale in the UK for example. Convert the GBP to USD and see what it's value is. Could likely ask $125 USD for it as it's about new? Still need a guy that needs it.

Scopes and Sights

These body covers were usually machined to spec for optic sights and fit tighter than the normal ones. Not rare but not common either.

Thanks for the help and information. If anyone has any idea where I can list it for sale please let me know.

You could list it here in the WTS forum, we have collectors of FN family rifles...one has an extensive collection.

Thanks will do that.
