Although LWRC International didn’t submit a candidate for the US Army’s Compact Semi Automatic Sniper System solicitation, they did develop one. This is their solution.
Obviously, this 12″ gun is chambered in 7.62 NATO. Now get this, it has a 20 position gas block. You should be able to run just about any ammo, suppressed or unsuppressed. It’s a monoforged upper receiver with an LWRCi NiCorr treated spiral fluted barrel. The CSASS comes standard with LWRCi Skirmish Back-Up Iron Sights. The lower is fully ambidextrous including bolt catch and release, magazine release and selector lever. The trigger is a Geissele SSA Two-Stage Precision model.

12″ 308 SBR sniper gun, for when you really want 308 to suck more than normal. I realize that 308 is more forgiving than 556 of velocity loss, but having shot some of these super compact suitcase sniper guns, there is a point of diminishing returns.
It looks like there were other barrel lengths that had been designed as well.
