The Firearm Blog goes over the SIG-Sauer M400 X-Series SDI, which is sorta the SIG Sauer SPEAR AR according to them... "In this episode of TFBTV, Hop checks out the new SIG-Sauer M400 X-Series SDI. Don’t let the awful, terrible, truly indefensibly bad name fool you, the X-Series SDI is actually pretty cool. This AR adopts some of the improvements of SIG’s Spear LT rifle and is more full-featured than the older M400 Tread series rifles.

"The Patented [US Patent No. D684,647] Gear Sector™ offset flashlight mount was designed to provide a low profile, ergonomic solution for attaching a weapon light to a Picatinny rail. We designed the mount to fit perfectly flush with the Tango Down® rail panels for an uninterrupted rail space.
On display during the IWA 2013 & Outdoor Classics is this new series of SIG Sauer Pistols called the X-Series. The Firearm Blog has even better information on these... "SIG SAUER (Germany) has launched a major new line of modular competition pistols. The line has 9 base models, 7 special/accessorized models, and 20 modular accessories. The new X-Series pistols are based on the SIG P226 X-Series and I believe supplants the old SIG P226 X line."
