Important Safety Warning
Aguila Quiet Colibri is a specialized primer-powered rimfire cartridge.
Your supplied product data includes this warning: these rounds must only be fired in handguns, and if fired in rifles, the bullet may remain lodged in the barrel.
Keep that warning visible on the product page.
Also note that Aguila’s current product page describes Colibri as designed for bolt-action or revolver platforms. Because warnings may vary by exact SKU, packaging, and production lot, buyers should follow the current box label and firearm manufacturer instructions before use.
Do not use this ammunition in semi-automatic firearms if reliable cycling is required. This load will not cycle the slide of most semi-automatic handguns.
Built for Quiet Close-Range Practice
Aguila Quiet Colibri 22 LR ammo is made for shooters who want very low noise and minimal recoil from a specialized rimfire load. Its 20 grain lead bullet and low velocity make it different from standard high-velocity .22 LR ammunition.
This product is best suited for controlled close-range practice in approved firearms. It is not intended for general-purpose rimfire shooting.
Best Uses
This Aguila Quiet Colibri 22 LR ammo is a practical choice for:
- Quiet close-range practice
- Low-recoil rimfire training
- Controlled target shooting
- Revolver use where appropriate
- Firearms approved for Colibri-style loads
Always confirm firearm compatibility before use.
Buyer Notes
This ammunition may not cycle semi-automatic firearms.
Because this is a low-power, primer-powered load, shooters must watch for possible bore obstruction. If a shot sounds unusual, feels weak, or the target is not struck, stop immediately and inspect the bore safely before firing again.
Use only in firearms marked for the correct caliber and approved for this type of load.
Buyers are responsible for following all federal, state, and local laws before purchasing or using ammunition.
