Design and key specifications
The ALEXANDER ARMS UST17 UPPER RECEIVER features an 18″ barrel with a 1:9 twist rate, tuned specifically for the 17 HMR bullet weights to stabilize projectiles for tight groups. The muzzle comes 1/2-28RH threaded and includes an A2 flash hider, giving you immediate muzzle protection and the option to attach alternative devices. The upper employs a blowback operating system well-suited to rimfire cartridges for simple, reliable cycling and easier maintenance.
What’s included and weight considerations
This upper ships in black and can be upgraded with Cerakote finishes for corrosion resistance and aesthetic customization. It includes two 10-round magazines and a parts kit for lower conversion, so you can outfit a dedicated 17 HMR AR quickly. At 4.5 pounds, the upper adds modest weight to a rifle while preserving balance for optic work and controlled follow-up shots. Priced at $989.99, it targets shooters who want a factory-configured, ready-to-shoot solution that reduces the work of parts sourcing. View product details
Performance and applications

The 1:9 twist and 18″ barrel length produce efficient velocities and inherent accuracy for targets out to the practical limits of the cartridge. The blowback action keeps operating complexity low, making field maintenance straightforward.
