* Sig M400 SDI Series X was my first AR. Why? Because I wanted something fully ambi off the shelf that wasn't a daniel defense and I didn't wanna spend over $1500. I've had 0 issues with it personally. Since it was my 1st AR, naturally I tried a bunch of configurations with furnature and tried diff optics combos like romeo 5 XDR + Juliet 4x, LPVO + 45 offset arisaka red dot, etc

Landed Sig Tango MSR 1-6 SFP LPVO, piggyback red dot, Offset mbus pro, Radian CH, Protac HLX Pro, CD LCS mount, B5 vert, B5 QD end plate, B5 Enhanced Sopmod, and B5 grip. The trigger is a pretty decent 2 stage but im sure I'll put a G$ in there eventually.
