So I’ve managed to source a few 106mm barrel options for my rmr build.
However upper parts kits are somewhat hard to find for the gen4.
Aside from the recoil spring and maybe empty chamber indicator, will most Gen3 parts work!
As well can anyone lead me towards a Canadian sticking dealer for parts kits?
