The standard modes will have the logo lasered into the front of the carrier while the lightweight model will not have the logo engraved.
I have the lightweight carrier and yes, the logo is laser etched into the carrier, barely visible but very well done.
I do t recommend this carrier unless you are co trolling both the gas pressure as well as the buffer tension. If so you will have a great, no recoil machine. I only use these in my builds.
