Anywhere online still have any of the x39 shorter barrel versions (i.e. not the 14") with the SBA3 brace? Prepper Gun Shop appears sold out.

I think a lot of manufacturers forego the AK mag compatibility in newer designs because of the utter crapshoot surplus AK mags are. Variations in dimensions, materials, quality, etc. No matter what they do, you still end up only working with 7 out of 10 magazines and having your product blamed for being junk because it won't run these rusty Egyptian magazines some dude found in grandpa's basement.
Sig 556R, PTR-32, PSA KS-47, and so on all suffer from this. There's no way a manufacturer can realistically test for all the possibilities, so then they end up hitching their best quality on the worst mag someone can find and post all over the internet. CZ using a proprietary mag makes sense in that world, plus it increases profits for them. Steyr was using their own design for the 7.62x39 AUG that's turned up at some Euro shows. The smart move would be for CZ, Steyr, and other interested parties to come up with a unified modern 7.62x39 design that was cross-compatible between firearms to help sell the idea of a refreshed ecosystem. It's been said before, but the fetishization of the AR/AK/Glock mag is tiresome and holds back sometimes better alternatives. |

These mags seem to be working fine for the French GIGN....
Progress is a good thing and CZ doesn't make garbage. Im sure these mags will be absolutely fine in the long run and the weight savings is fantastic. |

Still a niche, as almost everyone is moving to 5.56. |

In all other regards, though, it looks pretty awesome. They are small enough to be out of the way and not prone to be touched while firing, but if you retrain yourself, they are actually more convenient than the normal control on the left. Also, it's a ridiculously simple mechanism. It's all just one piece that slides up (or down) and is attached to the standard bolt hold open lever that an AR would have. (Push up, and it pushes up on the bolt hold lever, push down and it pulls the bolt hold lever down with it.) If it really bothered you, it'd be stupid simple to remove and not effect anything else at all, and you could use the control lever on the left, just like any AR. |

Anyone comment yet on how paper-thin the receiver is in those lightening cuts on the side? It's the one design choice that gives me some pause...but on the other hand, it's probably 7075-T6 and pretty dang tough, plus you'd have to strike the gun with something sharp to avoid the thicker sides of the pockets. I dunno how much better the SCAR would handle things in that department (and I don't plan on braining any of my guns with a ball-peen hammer)
Mostly the receiver looks like it'd be annoying to machine as nicely as they did it |

I'm loving the looks of the flash suppressor on this rifle, I'm wondering if it will be made available by itself in 1/2 x 28 so we can put it on anything we want to.

Can anyone who has a Bren 2s in 5.56, confirm if their flash supressor is bored out bigger for the 7.62x39?
