Why would anyone pay someone else to cut off shotgun barrels to a legal length (DB's contention) for $100 each? You can buy a hacksaw blade for your sawzall for about $6 and cut off ten or more before you ruin the blade. Legally.
In fact, why would you pay someone $100 to cut one down to a less than legal length? Anyone can cut off a shotgun barrel with a hacksaw, a sawzall, a chop saw w/carborundum blade or steel cutting blade. There is nothing special about it. With a good eye and a steady hand you can do a very nice job of it. It's not a gunsmithing level job. It's an 'average-construction-laborer-been-on-the-job-one-day' job.
Yep youve made me looks real dumb thar genius.
