Please note: AR15 receivers are in very high demand and very hard to find right now. I assure you we are running the machines full time and making weekly shipments to our distribution partners. If there is a particular receiver you are looking for, the best I can suggest is to sign up for the, "notify me when in stock" on Rainier Arms, Brownells, or Palmetto State Armory (or other) websites and then be ready to move quickly when you get the notification. Most inventory doesn't last a full day when it arrives at those online locations. I also suggest checking gunbroker.com. A lot of gun stores across the US will list their new-in-box inventory there so that site is always worth a look. - John Sharps. Founder, CEO. Sharps Bros.
