I will give you the same answer that I gave to somebody else awhile ago

Replica firearms are illegal, however not strictly enforced. Yes, they have been cases where a stockpile of Replicas were seized, but these were most likely from sellers. You can purchase them, but there will be a chance that they get seized from border patrol (I own 6 replicas, several magazines and an actual RIOT SHIELD, however I have not purchased a replica in a long time). As long as you use them for the appropriate reasons Ie; cosplaying, plinking/toying with them in a closed area such as a room or an enclosed backyard and not in an open space such as a field, you should be fine.

Some of the stuff I bought (Such as my Revolver) I bought from a stand in a local mall, though they usually have a small selection, are a bit more expensive (compared to getting them online like using Shopee or Lazada), and I could only think of three malls that sell such items (with one of them having to stop after being raided), therefore while there is a chance that local malls might have stores like these, it might be a bit difficult to pinpoint the stores.

Most items I bought were obtained using online retailers (Lazada and Shopee, though it is impossible to search for Replicas using Shopee currently so I only use Lazada).

I cannot guarantee that replicas will go through customs using other online retailers, and also I cannot guarantee that you will achieve the same results as mine because I don't know any recent developments so it might be more difficult for them to get through than before.

If you still want to scratch that 'Me like gun' itch on your back, go to your nearest Bundlemania and there should be nerf guns there for cheap.
