Learn about barrel blank manufacturing

We offer barrel blanks with industry leading precision. Entrust uses UNISIG precision machine tools in manufacturing, to elevate the standards for firearm accuracy with approachable costs. Our tech center can offer very short lead times on new barrel designs, due to our application experience, stocked material, and strong relationships with tooling suppliers.

The prototyping phase includes both part and process development, and prototype production. This allows customers to justify the purchase of dedicated UNISIG barrel manufacturing equipment, and simplifies the startup of production volumes in our customers’ own facilities.
