Semi vs Auto is a key point both philosophically and technically. You can not dismiss it and have any credibility.

Drop in sears were the key item in the easily modifiable. Both the sears and the designs that allowed for them were banned in the US. Also sales of open bolt designs were squashed. Again, key points if you understand what they mean.

Updates to modern weapons require that they be done to close to the same tolerances as the initial design. That is primarily for interchangeability and maintenance. Yes things could be done in a manner similar to what you reference, but the cost would be high and repeatability poor. It also takes some skill. The end product would not be selective fire if it was made from semi automatic firearms currently available in the US. Its reliability would be questionable.

You claim that specific words with specific meaning is geek speak is babble suitable only to those who do not understand that words have meaning and should be used properly. You assertions are the equivalent of claiming single payer is socialism. We don't tolerate that out of the repukes, why should be tolerate equivalent claptrap from you?
