I have an Armstrong receiver sight I took off of an 03 A3 sporter. It seems to be in working order and I am giving it a good cleaning and a once over. Are they collectable or have any monetary worth? Has anybody heard of this brand?

They were made in the mid 50's, I've had several on FN Deluxe sporters, there are at least 2 variations on FNs, worth about $50 depending on condition, they come up on eBay occasionally.

You have PM.

Do you want another one? It looks to be operational and in very good shape.
