Modifications to a 10/22
Gbodyolds, I trust you have a pretty clear picture by this time, but I'll belabor the point just a bit further.
Since three of your four posts to date deal with alterations/ modifications/ accessorizing the Ruger 10/22, I'll guess this is your major area of interest. Your fourth post deals with a possibly expensive restoration of an inexpensive shotgun. This all tends to indicate that you are still a novice with firearms.
Sir, you are most welcome on TFL, to learn and grow in your new knowledge. You'll find that most members here are eager to help the new enthusiasts, and also that they'll try to help you keep from running afoul of the various laws.
Sometimes a question is asked, "CAN such-and-such be done?" Frequently, the answer is "Yes, BUT . . ." None of us want to see a new person get into legal troubles by use of information garnered on TFL. Sometimes, the advice you receive (No, NO, DON'T DO THIS THING!) may seem a little strident. Believe me, this is out of concern for you and for us as well. YOU don't need legal problems, and TFL in general doesn't need bad publicity.
In line with the "Yes, BUT - -" answers - - I note your probable location. The "Authorities" in many large cities are very sensitive to modification of sporting arms which leads to the appearence or general effect of machine gunnery. Some modifications which might be perfectly acceptable in certain localities could possibly draw unwelcome attention in, say, the New York City or Boston metro areas. It wouldn't be the first time that installing a (n entirely legal) hand crank rapid fire device was misinterpreted, resulting in a lot of legal red tape.
Thanks to the other members who have given good counsel to the new member, on ways to avoid legal problems.
Best to all.
Johnny
