Lightweight hunter / squirrel (American Synthetic SR, Hunter Veil or Carbon)

Parts total: ~$170 + thread item (as of Oct 2026; excludes rifle, optics, ammo, tax, shipping)
| ID | Part | Price |
|---|---|---|
| C044 | Talley 11 mm steel rimfire rings | $69.95 |
| C025 | YoDave CZ-457 trigger spring kit (set >= factory-safe weight for field use) | ~$20 (est., not captured) |
| C049 | Spare CZ 5-rd polymer mag | $39.95 |
| C067 | 1/2x28 thread protector / suppressor-ready | varies |
| C053 | 5-rd .22 WMR/.17 HMR mag (if adding a magnum barrel) | $39.95 |
| Total | ~$170 + thread item |
Why: - Rings on the dovetail keep weight down (the Carbon is 2.15 kg). - The spring kit keeps factory adjustability. - A flush 5-rd mag keeps the profile slim.
Add-on: a CZ .17 HMR/.22 WMR Varmint or American SR barrel set (C028/C031, $299) for a two-caliber hunting rifle. Remove the .22 LR mag-housing insert (C056) when running magnum.
