LSW Parts-L86A1 (SA80)

Hi guys,
I have the upper receiver, NO BARREL, complete bolt (A1), spring guides, outrigger, flash hider, bipod and a few other bits from the LSW version of the British L86A1 Light Support Weapon which I am considering selling and I honestly have no idea of its value. I know that the new L85A3= SA80A3 is using the LSW receivers as the foundation of the recent upgrades.
Could any members give me a ballpark on this matter? I had collected the parts over the last decade to make a dummy LSW for my collection by adding these parts to a Airsoft version, but have decided that I need the funds for another project. Any help will be greatly appreciated.
ATB,
Wesley
