For the last couple years I have been making Followers for the three big bore AR rounds. It all started after I bought my 450 bushmaster and went looking for magazines. At that time no gun shop that I could find carried magazines, so I pitched the idea of making followers to a friend and that launched a new business, Chamber Tactical. We make these parts in our small shop. We make our own molds and inject the parts ourselves.
After creating a successful Follower, we came up with the idea of making a conversion adapter to quickly and easily convert the AR magazine back to any other caliber that one might have. Now I use the same magazine for my 450 bushmaster and my 223 AR-15's.
We also make a magazine capacity limiting device.

Here are a couple links to our website, some instructional videos we put on YouTube. We also sell on Ebay.
