Great review, and nice to see it in one uninterupted piece as well. Small note, on the last-but-one picture (comparison of magazines), you've got the MP7 and G19 mags the wrong way round.

Probably an LCD. I'll try and source as much as I can locally (a metal pipe doesn't need importing from the States ), then order what bits I need to finish it (blade, emittor, etc).
