An in-depth review of the new Krytac MKII CRB and SPR AEGs is done by VIPAirsoft in this video... "The new Krytac MkII's deserve a long and in-depth review to talk about how great it is for a company to make these small changes. I do hope you stay for that discussion, but if you're only interested in the pure review, that's fine as well. Just give these fantastic guns a look, and find @KrytacArms and @KrissArms on Instagram and elsewhere, and let them know how great it is that they've done this."
