1 = A Decent .22lr Semi,
the other is a toy that happens to be able to shoot / fire .22 lr..

ok, so a S & W is plastic...., but,
you try to strip & clean a Colt ..!!?!!! or change the trigger group !!??!!

as was already well said....
1 was built to look like an AR the other was built like an AR..
