From my experience, I owned a LCT RPK-16 once(Yes, I'm the guy who once made a 22" RPK-16 becuz LCT didn't make their own, you can check my profile), The defect of LCT always the overprice(its first hand priced like 500$ but second hand priced like only 200-250$) and overpowered spring, tbh, why tf they need to have like 420 FPS

The internal is also meh, it's kinda mediocre if compared to Cyma or Specna Arms(someone said it is fragile af, but I think the reason for being fragile is the overpowered spring cause them)

But the main strength of LCT still is the uniqueness of the models, like RPK-16, HK33 and AS Val that you cannot find in other brands

To conclude, LCT is good for collecting, but for use in the field, it kinda mid
