Good insight, I'm of a similar suspicion re: the hypothetical digitization and retention of 4473’s you've described. Good thing for 80% lowers. For now.
Speak with civility, or leave the discussion. This is a forum for responsible, mutually respectable adults. We do not have time to coddle to the immature and flagrantly-spoken.
Form 4473 records individual information pertaining to the firearm and buyer. The numbers reported by the FBI only record NICS background checks. Call them yourself and confirm, like I did.
https://www.80-lower.com/ Better kits at a better price can be had here, in my humble opinion. Nitrided barrels, free-float lightweight guards with torque plates and centering bars for the top rail to line up w/ the receiver, good parts kit and triggers, very affordable. There’s also a pretty good selection of pistol kits (1911, glock, sig, etc)
Respectfully, I disagree. I wouldn’t risk blowing my ear drums out at the range, ever. Especially considering it’s going to ruin my auditory situational awareness if it’s ever needed. — Fires NCO/JFO, ret. (with Tinnitus)
You illustrate the point perfectly with this product as an example: Where does the limit of vagueness end? By Shapiro’s own words, a firearm is to be defined by its physical shape. There is nothing else substantial — or even logical or measurable — in his brief. My hope is his office becomes inundated with examples of “homemade firearms”, because by his words, damn-near everything capable of withstand a little heat and pressure could be considered a firearm.
You’re certainly right on the technical specifications and ballistic comparisons of 300 bLK to 7.62, .45 ACP, et al.
Except many shooters do enjoy this round because it provides unique advantages, like the ability to swap from supersonic to subsonic and suppressed with nothing more than a magazine change. Most would agree a cartridge with the ballistic performance of .45 ACP and the stability, accuracy, and increased range of the AR platform far out-performs any other sub-gun or pistol configuration.
It’s also important to remember 300 BLK was developed specifically for US special operations. It doesn’t translate into much practical use in the civilian world, but it’s a wickedly fun (and still potent) cartridge nonetheless.
