Thanks! The info provided is very helpful. We have a buyer for the FN30's. Now we can sell the a4's.

Thanks for the response. My purpose is to put together functional kits for sale. Here are some additional pics that may help. https://imgur.com/a/Nr6WBdz

https://imgur.com/a/wN5Ot72 https://imgur.com/a/PvzFieq My first post, so, please forgive any mistakes. I am helping a friend sell several FN30 kits that belonged to his dad. The kits have been mixed up, and includes spares and other parts. I have figured out most parts, but there are variations in parts I cannot figure out. First up are the barrel extensions/bolt carriers. Can anybody let me know what are the reasons for the differences? Thanks.
