WE also makes a Tan HK 416, I just sold one a few weeks ago.
Aside from repeating what Ballcancer just mentioned, if you're dead set on a 416 just for plinking then grab a WE. Great externals and in my personal use, good enough internals that if you don't mess with anything they're good to go OOB.
I've owned 7 of these things so far and not had any serious breakages or anything that even a novice couldn't fix. The 416 is especially easy to take down, even more so than a regular AR.
