I have 2, a second hand XM177E2 I bought from a guy in the Netherlands and also a Model 602 I had custom ordered from VT directly. I live in the UK and had no problems getting either of them shipped to the UK. I've heard horror stories from before and during covid but since then, at least for me I got them both within a week or 2 of them getting shipped out.
Long story short: the hefty price tag is for the highest quality replica of a real AR-15 with the best recoil you'll ever experience. All depends if its worth it to you spending the money or not. There isn't much information out there to go by in terms of research but I will point you in the direction of Catgut of Explosive Enterprises. He has done extensive experimenting and custom work on the Vipertech platform and is probably the best source of info regarding them. Start with this video and work though the rest of his videos and you'll get a good idea of the kind of thing you're getting into. 
Any other questions I'll be happy to answer or if you want to DM any time feel free🙂
