Last night i ordered online direct from ST their lower receiver w/ enhanced kit and without stock. For the stock i plan to put Magpul CTR or Vltor Imod. I been wanting to build an AR with Spike's Tactical or RRA lower receiver. And made up my mind with ST lower as i feel in love to the Spider logo so much. This build will be my 2nd AR as my 1st was a complete DD v4. And now i'm still debating of the upper receiver. Whether should i get the DD SBR MK18 or the Spike's 11'5 with 9" SAR. My question.. had any of you ordered lower receiver from ST and how long was the wait? And should i get the ST or DD SBR? Thank you for any inputs or tips.
