I've seen some discussion (generally negative) about the Roni conversion system.
I've recently come across the Triarii carbine conversion system by HERA.
Does anyone have any experience with these?
What are the differences, if any?
Further, to legally purchase any firearm in South Africa is very difficult. To get a proper carbine is even more so.
Bearing that in mind, is there any benefit to using a carbine conversion system?
