This upper includes a gas piston system and comes with one .17 WSM magazine that’ll work with your standard MILSPEC lower receiver. It also requires an A2-style or rifle-length buffer tube and spring to cycle correctly. Some aftermarket triggers might not provide reliable ignition with this cartridge; check with the trigger manufacturer to ensure compatibility – you’ll want a full-power hammer spring and full-weight hammer if you’re swapping triggers.
We’ve had folks use these for varmint control on larger properties outside of Birmingham, and they perform well for keeping small game under control. It’s also a good option for a dedicated .17 WSM upper for precision shooting. This isn’t a heavy barrel, so it’s manageable for all-day use in the Alabama heat.
