Handgaurd/Furniture kit question.
 

First of all, will this get through customs: Link

Secondly, will it fit onto my m4? Here are some photos of the one handguard i have right now:

Due to the angle it looks fairly larger. The hand guard photoed is 6 2/4 inch.

Thanks a lot for the positive answers. People who post negatively will be ignored.

Hand guards usually pass through customs fine. Although customs may take it just because they want to. Thats my positive comment.

Heres my negative one, your a lazy and people are gona get sick of spoon feeding you.

ya it will fit, but minor mods might be necessary. it's just grinding a small part off, not so bad.

and yes, it will pass through, For me, it did anyways.

The only reason why i ask so many questions is because I'm new to the sport. I haven't owned any full-metal AEG's, or even any named brands. I've googled hundreds of different variations of airsoft questions and got hardly any answers. Sorry if it's upsetting the community. I just know I'd be lost by myself for the time being.
