It's a Choate. It comes from the factory in straight black ABS, with two thin strips of very coarse checkering on the forearm and pistol grip. I did the wraparound stipling with a woodburner and applied the paintjob myself. Since that photo, I've added a picatinny handguard and some optics...
I'd like to do that too. In fact it's higher priority than the stock. What was the source of the picatinny rail. I've only found one, for the carbine, and they are right proud of it, as compared to similar mounts for the somewhat similar Mini-14
