I think it’s closer than pairing it with an LMT. I used to actually have an LMT, but it’s my uncle’s now. The SR-30 is just an SR-15 lower with an H2 buffer. I paired my SR-30 lower with a 14.5” SR-15 upper to make it a complete KAC rifle
It certainly is but now with the new cali laws it's nearly undesirable to buy a new lower with it's identification and needing to register as an "assault weapon."
