I guess they draw the line when things start to become canons/explosives rather than firearms?
There aren't any guns that are illegal in our Great Commonwealth (see below for funny exceptions). Cannon are fine. Explosives are fine. Tanks with cannon, etc.
There actually are a couple of firearms that are technically illegal in Pennsylvania but I don't think anybody has ever been charged with it. It is not intentional, it is due to unexpected conflicts in the laws. One is a "sawed off" black powder shotgun. But a real "sawed off" shotgun (short barreled shotgun, SBR) is legal
Thee is one other quirk like that I think. But other than that, all guns are legal.
Regarding explosives, they are legal but there are storage requirements if you keep them for more than 24 hours, licensing requirements for high explosives kept for more than 24 hours, and serious federal transportation requirements.
However, Explosive Destructive Devices are illegal in Pennsylvania. This would be hand grenades, mines, explosives turned into weapons. It also includes projectiles containing explosives over 1/4 oz. per projectile. The .50 caliber Raufos MK211 round contains just a hair under 1/4 oz of RDX and is legal in Pennsylvania. There are also a few 20mm High-Explosive rounds which contain 1/4 oz of explosive. Once we get above that, we can't own them in Pennsylvania if they have an explosive filler. However, 1/4 oz is also a federal cuttoff that would require a $200 tax stamp
per device (per round/grenade/etc.) anywhere in the US unless you decide to be a licensed dealer or manufacturer. So for the average Pennsylvanian it doesn't mean that much.
Also, keep in mind, unless you want to get a dealer's license or a manufacturer's license (which you certainly can) then all civilian machineguns in the US have receivers registered by 1986. So they are very expensive, around $4,000 for a MAC M-10 and around $12,000 for the cheapest rock-bottom version of a converted M16 (up to $25,000 for factory guns). While this is all extraordinarily expensive, that brings necessity into play. And necessity is the mother of invention
A 1986 receiver (or even a simple registered sear part) does not an old gun make. You can change anything you want on it within reason. M16s can be turned into belt feds in multiple calibers including .22. Every machinegun has a .22 conversion available for it with giant magazines
That $4,000 MAC can shoot 9mm, .45 caliber, 7.62x25, .380, .22, 5.56 (although the SABRE is suspended and we are waiting for a newcomer). One machinegun can be a subgun, an assault rifle, a light machinegun, and a beltfed in 10, 20, or 30 calibers.
