Thats a general issue with attaching items to each other. Guns are always the same size regardless of having a buttstock/scope/suppressor or not.
Combining a gas stove, gas canister and cooking pot/frying pan will always result in a 1x2 item even though the parts are 1x2, 1x/2 and 2x2. You can even store items inside the pot/pan.
