I bought one on a whim at a gun show yesterday. As noted, it's got all the ergonomics of a brick. Also, it's a pain to disassemble completely. There is a little guide rod and a plate that are almost impossible to get out, and even less easy to get back in. I ended up needing to use two sets of needle-nose pliers to get the thing back together. Just not enough room to get the fingers in there. It would have been helpful to have a 3rd hand too.
Oh yeah - the trigger is pretty heavy too. The trigger internals actually look pretty similar to how a Glock works. From the top, it almost looks like they may use some OEM Glock parts. Not sure though. I wonder if I could get a Glock target connector in there and help with the trigger pull.
The cocking... things... are pretty stiff, and have a pretty small front face. I can see them making for sore fingers / hands after not many reloads. It almost looks like it would work best pushing the charging rod in on the side of a table at the range. And yeah - there is the thing about having your hand out near the muzzle when charging the chamber.
Ruger BX-25 mags reportedly don't run in the gun. They supposedly have a mag spring upgrade that you have to buy for each mag to get them to work (watch the manufacturer's website videos. All I've ever seen featured on there was the Ruger 10-round mags.) No telling if any of the aftermarket mags will run or not. It's been snowing here so I haven't had a chance to try this thing out yet. I'll see what runs when I get a chance.
I do like that the barrel is easily removable. I'm thinking of sending it off to get threaded, and add a 1/2-28 adapter so I can run it suppressed.
The website shows a goofy-looking buttstock adapter. To be honest, I think they would be better off making a bullpup chassis and offering a 16" barrel to go with it. The way it's put together, it would be easy to install a longer barrel.
Despite all of this, it's still an interesting design. I'm hoping it will be decent. For $200-ish, I'm not out too much if it's a dog.
