Bear Creek Arsenal's New BC-15 17HMR Billet Upper Receiver
The .17HMR is one of my favorite rimfire calibers. The hot 17 caliber rimfire cartridge is both supremely accurate, and light recoiling making it a good step up from .22LR in terms of both inherent accuracy and range. Bear Creek Arsenal is following up the success of their .22WMR AR-15 upper with the release of the new BC-15 17HMR Billet Upper Receiver to give rimfire enthusiasts access to yet another popular rimfire cartridge that they can plink, hunt, or target shoot with by simply slapping it on an AR-15 lower receiver.

Is there something about the shape of the .17 HMR cartridge that limits mag capacity to 10 rounds? I never see .17 HMR guns with ~30 round mags and I’m guessing there’s a reason for it that I’m unaware of.
What is the operating mechanism they're using here? If it's straight blowback, then it's going to be recalled and discontinued like EVERY OTHER BLOWBACK 17HMR that has ever reached the market.
They blow up and cause issues. The only semi-auto 17hmr's that remain on the market these days are using a delay system or some other operation. But blowback guns blow up and get recalled/discontinued every single time.
