David Crane at Defense Review has an interview (and some of DF's trade-mark high-quality pictures) on Primary Weapon Systems new Diablo SBR, an item unveiled at SHOT Show. It's a seven inch barrelled, gas-piston AR with a proprietary flash hider/compensator. It's a great interview and it's fascinating to hear a little behind-the-scenes on the development of the system. The comments about the design of the flash-hider are especially interesting. The video below shows the Diablo in action- and PWS' claims about controllability on full-auto seem to be completely spot on.
