the ACR subsection of the armory is slightly dead, but we do have 3 other rifle types (that i an think of) that do not have a home and could be joined with the ACR group as they all have a similar function and style

so i am suggesting the subsection become piston rifle forum]
including acr, cz bren, beretta arx100 and rob arms xcr. 
they are all folding stock, piston rifles who do not have a home in our forums.
