Don’t let our competitive price fool you about the quality. Our modern manufacturing facility allows us to manufacture precision machined  firearm accessories, threaded adapter / converter and protectors at a popular prices.

Every Hughes thread adapter is CNC machined to precision tolerances. Hughes Precision threaded adapters are manufactured using AISI 4140 Alloy Steel-US (the same alloy steel used in firearm barrels). Hughes Precision threaded adapters are machined on Swiss Type CNC Lathes ensuring exact internal and external thread alignment (concentricity* and angular alignment*).

* Concentricity  is a complex tolerance used to establish a tolerance zone for the median points of a cylindrical or spherical part feature. Concentricity is generally reserved for high-precision parts, and only when there is a need to control median points.

*Angular Alignment.  Angular misalignment involves an angle just as the name implies. It occurs when one of the bore or thread axes is at an angle in relation to the other. It’s as if you have a broken tree branch; if the lines of each were extended, they would intersect, but are not parallel.

Hughes Precision Products LLC manufactures thread adapters for firearm manufacturers, firearm wholesalers, local retail gun shops and our you on-line internet customers.

 Manufactured From AISI 4140 Alloy Steel With Black Oxide (blued) Finish.

All products are manufactured by Hughes Precision Products, LLC

We only make parts for the shooting sports.
