In this episode of TFBTV, @Hoplopfheil 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. But it also costs way more, so it really ought to be. ⇒ SUPPORT US AND WIN FREE GEAR EVERY MONTH ⇐ TFBTV is viewer supported. We need you.
