Drop shipped means illegally coming from Czech. Illegal because you actually need an export license for firearm parts, and the guys Zahal deals with just ship the parts by mail without that license. If it's from Israel, the shipping is quite quick, but if it's from Czech and they don't have it in stock you'll be waiting for a while. Their communication is poor, and the communication out of Czech is even worse so Zahal doesn't know what's going on if there's a delay on the Czech side. Inventory numbers from the Czech side is not accurately reflected on Zahal's website. I would honestly try my hardest to deal with Canadian companies like Wolverine, Wanstalls, Corwin Arms and SFRC. Between the four you should be able to get all the parts you need.
