WARNING ABOUT MIXING KT 420 AND GEN 2 FORENDS
Everything I have illustrated so far has shown only Gen2 forends used together, but several people have mentioned using a Gen2 forend to extend a Kel Tec 420 forend. I started a mockup of that concept tonight and it appears the KT 420 may not actually center on the barrel but instead hangs below center while the Gen 2 is generally centered. If that is correct, the top and bottom picatinny rails may not line up. See unfinished illustration below. It is still usable but you would not be able to bridge a mount across the sections. On the other hand, it could just be that my sizing is off on the Gen 2 image (too large). That would explain the top rail not lining up but not the bottom.
Can someone who has installed the KT 420 and has both sections check this and report?
