“Every great company goes through an evolution cycle. I am proud of what we’ve built and where we will take this company under the ZRODELTA brand.”Mark Deros
We began with the startup of an aluminum foundry manufacturing machined components for racing motorcycles in 1960. This introduction into the world of metal casting soon outran motorcycles and over the next 25 years spawned a full service foundry organization producing foundry patterns, tooling and a wide range of aluminum, bronze and iron castings.
In 1985, we began offering assistance to customers in procurement of tooling and all manner of cast products. With our foundry background, we were able to assist and become the “one-stop” shop for tooling, castings, machining and become the managers of the customers’ inventory. As we progressed, in 2000, to assure quality products and positive deliveries, we initiated another change in our organization. We built our first building, bought our first CNC lathe along with some manual machinery and started full, finished and inventoried products for turn-key complete products for our customers.
Now, with the best staff available, we have grown our ISO 9001:2008 certified U.S. facility to over 66,000 square feet, dozens of precision CNC lathes and mills, fully-automated Laser Cutter, CNC Press Brake, fabrication capabilities, and full CAD/CAM engineering facilities to service a wide range of products and a wide variety of customers and industries. Our coatings shop, Coating Specialists, was formed recently to fulfill our customer needs in Cerakote, hydrographics, powder coating and other processes.
Today, ZRODelta, a division of CSJB Holdings, Inc., through the license acquisition of all products, technology, and IP of Samak Enterprises (Alamo Four Star (A4S)), manufactures quality optic mounts and firearm accessories. ZRODelta carries forward the reputation for quality mounting solutions, muzzle brakes, and other precision shooting related accessories.
Samak Enterprises Founder, Mark Deros, comments: “Every great company goes through an evolution cycle. I am proud of what we’ve built and where we will take this company under the ZRODelta brand.” Deros remains an active participant to oversee product development as the company is already expanding its line of optic mounts to include custom OEM offerings.
ZRODelta (formerly Alamo Four Star) is a world-wide leader in firearm accessories for military, recreation, and sport shooting needs. Our work stands apart in quality and effectiveness. With our patented and patent pending products, you can be certain that any critical firearms need is met and exceeded in even the harshest conditions.
All mounting products are fashioned around the patented DLOC M1913 rail interface. The DLOC uses a unique rail interface that allows for consistent zeros and a damage free method of attaching accessories to the M1913 rail allowing to quickly change optics without needing to re-zero your rifle every time.
Our Cowl Induction Breaks reduce recoil by up to 71% while managing muzzle rise and reduces sound directed toward the shooter. Our cross milled port design redirects escaping gas to increase efficiency over the standard muzzle break, reducing recoil and adding to the enjoyment of time spent at the range.
We pride ourselves as a U.S. based manufacturer of quality optic mounting systems and accessories for precision shooting, and bring our passion and innovation to work with us each and every day.
