Kel-Tec PR57 5.7x28mm 4.64" Pistol Black 20rd - $249.99

I don't think there is any mechanical or tactical advantage to top load, but I don't think that is the point of this design. Considering the many restrictive states, counties, cities regarding magazines and appearances, I believe this design is an option to allow higher than 10 round counts for those buyers. Just my guess on this Kel-Tec product. As an FFL holder I am absolutely disgusted by the obscene and endless laws I and my customers have to navigate. "Infringe" is an understatement.

Otter Creek Polonium 30 - $439.99 (Add to Cart for Best Price)

I did indeed do that and it wasn’t working. Also the $532 was a reduction from a higher price $589 IIRC when added to cart. Looks like this was fixed. Thanks for being a master of the obvious.

INLAND Suppressor 22LR BLK Aluminum - $225.99

There needs to be more companies to embrace the maglite styling on cans. The fancy designs add machine time and cost. Give us knurled black tubes.

Kel-Tec PR57 5.7x28mm 4.64" Pistol Black 20rd - $249.99

Can anyone actually see the advantage of having to top load a pistol one by one or with clips?? I'm respectfully curious.They are saying the 21 round capacity is an advantage but just about every other 5.7 pistol have near or the same capacity with mags..so I don't understand why anyone would buy this over say a TISAS 5.7, RUGER 5.7 and PSA 5.7. The other question is what happens if you have a malfunction or failure? How do you clear it fast? You obviously can't strip the mag and clear the round then quickly change mags to stay in the fight if needed.
I'm truly curious. If I missed something about it let me know respectfully

Feyachi HL-20 Pistol Light 1500 Lumen Upgrade LED Weapon Light Compact Rail Mounted Handgun Tactical Flashlight Rail Locating Keys for Picatinny, Sand - $24.54

I've got no issues with mine. Lives on the pic rail on my 9" AR22 so the light is about flush with the end of the hand guard. The switch falls right where my fingers are while gripping. A couple thousand rounds and no issues. Have hit some barriers, chairs and tables. Still lights up. And the fde isn't too far off my handguard's color. So it looks decent too. I do like pistol lights on SBR's due to hand placement and use.

Not a bad deal considering how hard these are to find in stock currently.
