Anthony "Croc" is a stand up guy. I trusted a large build with him for a rare spec item. He stayed in contact with me on all timing or acquiring the HTF parts, build was done proper, final product was flawless. I had over $4k tied up in this build that took over a year.....well worth it and I would trust them fully.
That said, he is a true builder with attention to detail, that means that he is working most of the time and not spending time advertising or 'building an online brand'. In fact I can't remember how I was introduced, but it was not via the internet, it was word of mouth with trusted shooters and armorers that I personally know and trust. Their recommendation did not let me down and best way is to call them directly on the phone. 98% of the time they he picked up without a call back.
Phone number can be found by searching the business name of U.S. Equipment LLC, DBA Croc's Gunshop. Glorieta, NM. They cater to the vocational shooter (people that need these for their job and life depends on it). They won't let you down if you purchase from them.
Good luck!
