No it's a "good thing"
Not at all...how is one to get parts? As well none of those that are cut are transferable anyway...so it's not like the average joe can buy one.
I'm glad people are importing parts kits, reimporting lend/lease kits etc.
It's the only way people can keep their transferables running.
What kills me is when someone chops of a post sample of a gun that's hard to get...that kills me....
