Lots of people make add-ons for the AK, but I was actually rather taken aback by the M10X rifle being announced by M+M Industries (at the time of this writing, there is nothing about the new rifle on their web site) at SHOT this year. They really have done something different, and it looks both interesting and promising.
Picture taking a normal AK, removing the rear sight block and dust cover, and pinning a full-length handguard and receiver cover to the front of the receiver. The gun has a disassembly latch underneath where the stock attached to the receiver, and allow the whole thing to pivot open like an AR or FAL. The monolithic handgard includes a single rail running the entire length of the gun, so you can put on an optic or use iron sights back at the rear of the receiver (and not have to work around the standard AK’s lack of solid mounting points back there.
The rifle uses standard AK mags, standard AK fire control parts, and AR-compatible stocks. All in all, I think it’s a refreshingly original take on the AK with a lot of very real improvements, and I’m eager to see how well they work!
