Guess I should've put "air gun" accessory in all caps or something.
I see guys selling standard cap mags on there calling them "Pinned at 10 rounds" but no sales to banned states lol. Some are bold enough to put 15 or 17 live rounds next to them. Plenty of bids.
Be a good way to scam folks. They get a real 10 round mag, they really have no ground to stand on.
