Robinson XCR-L

And a PPS43

I haven't shot the XCR yet (got it today) but man was it ever an odyssey of lies and ineptitude getting it. The dealer I got it through said he wouldn't be ordering any more, ever, unless Robinson starts going through distributers. I don't blame him. I'll save the story for when someone asks.
It's obviously built really well. The fit and finish is great and the parts all work together like nicely designed and machined parts should. The stock opens and closes easier and smoother than any side-folder I've ever used. It's unbelievably easy to change calibers (and several calibers are actually available for it, unlike other multi-caliber rifles out right now), and it's all metal instead of polymer. Polymer doesn't bother me, but it's nice to have a metal lower in a rifle like this. If it shoots as well as it's built, and is reliable, then it's a winner for sure. The only thing that bothers me a bit is the fact that every part in this rifle is unique to the XCR (no commonality with ARs, for example), and Robinson's long-term viability is an issue. They'll probably be around, since they clearly don't want to get bigger, but it's conceivable that parts may be a problem in the distant future if they go under. I'm going to shoot it Friday morning so I'll have a basic idea of what that's like soon.
I have, however, shot the PPS, and man is that a fun gun to shoot! It's 7.62 x 25, which is dirt cheap (I got 1,260 rounds for $100), and is a much more suitable caliber for a subgun than 9mm. I have several pistols in that caliber as well. The stock is pinned in place, but if you're willing to title the receiver, you could "un-pin" it. Worst case scenario would be milling the parts out and replacing them with a cheap parts kit, which are available. The barrel is already the standard short length, so the stock is all you'd have to do after getting your SBR paperwork approved. The thing is accurate, fast-firing, and gets a lot of questions from people around you. I brought three different types of ammo, and it shot the Russian and Polish stuff flawlessly. The Romanian ammo was inconsistent enough to be useless. Some rounds were so overpowered it was like shooting a 10mm, and others were so underpowered they felt like a .22 and wouldn't cycle the bolt. Everything in between, too. That was a box I picked up at a gun show a few years ago, rather than from a sealed tin, so I won't indict all Romanian ammo based on this one instance. I have a whole tin of it that I'm going to break open and shoot some from it on Friday.
It's built by the Łucznik Arms Factory in Radom, Poland, so you're getting it right from the Commie source. No mismatched parts on built-up American receivers; this is all Polish and built by a company that's been doing it forever. Their American name is Pioneer Arms, but it's the same factory that makes assault rifles, pistols, and subguns for the Polish military. It was taken over by the Germans in WWII, and went back to polish/soviet control after that mess was sorted out. So there's a lot of history here, if you're into that.
Best thing about the PPS? $449, with four mags, and all the ammo you can shoot for about eight cents per round! They have a bunch of them at both Bill's locations.
