Palmetto State Armory has a Glock lower. That would prevent have to use a mag block, give shorter OAL, and prices are pretty attractive. They offer pistol-length uppers, as well.
I will probably do a more detailed review of the Kriss and hopefully compare it to a few other 9x19 carbines, possibly including the 9mm AR if its done by then. However, I need some more time with it. Although my initial impressions are favorable, I need more time with the gun and more rounds through it.
I personally find all those choices too busy, I like the simple straight stock conventional set ups like the Ruger PC-9 or Marlin Camp series.
Pics?
It would be very easy to SBR and/or thread a Camp Rifle. I don't know why it would be any different. It's also drilled and tapped for a standard 1894/336 scope base so mounting ANY optic would be easy. Same for the Ruger. Both are good designs that were discontinued due to lack of sales.I'm not sure what you consider "busy." However, I will say this. The Marlin camp doesn't offer anything I was looking for. Its not small or compact. It is not a good SBR candidate. It would take considerable effort to thread it for a suppressor. Mag capacity is limited. Its not conducive to mounting a red dot sight. In sum, it doesn't do any of the things I wanted this gun to do. Oh, and it has been out of production since 1999 (likely for a reason.) The Ruger is basically the same thing but it has only been out of production for about 10 years.
My suggestion. Or if your looking for something a little neater you might want to look at the keltec folding carbines.In 9 and 40 using Berreta pistol mags. This rifle is very high quality and is my preference over the JR Carbine. The JR Carbine doesn't hold open after the last round. My friend does competition in PPC with it.

There is no shortage of folks waiting for you to send them a barrel to shorten and thread. I just received a factory 10/22 barrel cut to 16", threaded, with the front sight reattached, bead blasted and blued for the princely sum of $100. Sure, sending a Camp Rifle barrel off to be modified might be a wee bit more difficult than swapping the barrel on an AR or adding a buttstock to a pistol but it's still easy.I suppose the marlin and ruger are easy to sbs and thread if you have a lathe. I don't. Pulling a push pin and installing a stock is a MUCH easier proposition. Getting a rds on the gun is only part of having a gun properly set up for an optic. The ruger/Marlin appear that they would have cheek weld/sight height issues and no ability to co-witness.
Even if you had the equipment and skills to cut the barrel, move the front sight, thread the barrel, etc you still wouldn't have what many of the options above offer.

Not semantics at all. You said the Marlin was not conducive to mounting an RDS and that is simply not true. As far as cheek weld issues, it's no different from mounting an optic on any other rifle with iron sights. In other words, not an issue 99.99% of the time.Even more complicated when one is making an SBR. I'm not really interested in bickering over the semantics of mounting a RDS. I will say when you mount an optic higher than the irons were you have cheekweld issues. Co-witness may or may not matter depending on use. For a fun gun its less important to me. Point is, neither of those long since discontinued weapons really fit into the niche I want this gun to fill nor do I have any interest in them.
