Schmeisser SP15 in .222 Rem - a black rifle turned FDE (or something like that!)

Okay, this is the same rifle, but in yet another video - how many of them have I already published to glorify her?... Far too many, that's for sure, but this one could be the ultimate version of my German girl - well, hopefully! ;)
One of the latest additions to this setup is a Magpul PMAG 30 rounder pinned to 10 rounds to conform to European legislation. I initially thought it was supposed to be in Flat Dark Earth but it isn't: it is officially Medium Coyote Tan, which happens to be the (exact?) same colour as my Warne X-Skel mount - so much for the all-FDE setup! ^^

Why is it in 222 and not 223 Remington?

Hi,
It is an ar15 lower or just something who looks similar ?
Thanks !

The lower is I think the same as on the regular semi-auto Schmeisser AR-15. The bolt and bolt carrier group are definitely AR-15. The main difference is the absence of every part that is related to the gas system, although the gas port is still present on the carrier. Ah, there is no forward assist on this Schmeisser either!
