Knowing Kel-Tec, looking at the actual rifle, looking over schematics as compared to the SU-16/PLR-16, and then looking at what is already out there in 7.62mm, I would bet on actual retail in the $1,200-$1,500 range for the 18" and 24" guns, with the 32 incher being a good $200-$300 higher. There was a whole lot more engineering in that than the SU/PLR. Also looks like a lot more steel, which means higher production costs.
If it comes in cheaper, great. If not, it will still be the ONLY bullpup 7.62mm on the US market. The fact that it uses cheap and readily available FAL mags is a big plus.
The only thing that even comes close to that size/weight is the JLD PTR-91 Para, which goes for ~$1,400.
That KT is a good bit shorter and lighter than my AR-10 carbine, even with the stock fully forward.
I will definitely be driving the local shops crazy trying to get one as the time nears.
