San Tan Tactical®, Hornady Mfg®, and Proof Research® have partnered up on the San Tan new 6ARC rifles. San Tan’s innovative high-quality firearm systems and unparalleled performance in combination with Hornady’s New 6ARC round originally developed for a specialized group within the US DoD, and Proof Research premium carbon fiber barrels take the AR15 platform to a whole new level!

Think the AR platform is only good for target shooting, self-defense, predator and varmint hunting? Think again with the San Tan Tactical STT-15 Big Bore PILLAR Billet Upper Receiver. For starters, the STT-15 Big Bore PILLAR upper receiver is incredibly light coming in at 8.2oz! It features an enlarged ejection port to freely pass .458 SOCOM all the way up to .50 BEOWULF. We designed the STT-15 Big Bore PILLAR upper receiver to overcome the shortcomings we saw in the current offerings. It needed to be lighter, stronger, and different, and all while looking good doing it. We weren’t going to settle for just hacking another receiver out of a block and calling it good!

STT-15 Review By: Nomad, Photography By: Nomad & Will

I was super excited to hear from Will at Black Sheep Warrior when he asked me to build out and field test a receiver set from Chandler Ariz. based, San Tan Tactical (STT).  Possibly like some of you, I had never heard of STT. 

First order of business, visit google and recon this company. I quickly located their website (www.santantactical.com) and began studying their handiwork. I could tell by their mission statement they seemed to care a lot about their work and their customers. The photos and videos on their website were well done and the site itself was very easy to navigate. After I had scoured the entire site, I got offline and began thinking about what parts I would choose to mate with the inbound receiver set.

Chris Tran recently had a chance to take a look at San Tan Tactical’s revolutionary AR lower dubbed the STT-15. After initially dismissing it as just another gimmicky lower, he took a closer look, was absolutely won over and wrote up a comprehensive review.
