1866 CO2 Rifle & Compatible Items

The .177 versions can. They come with a smoothbore barrel that fires .177 steel BBs or .177 pellets at up to 600 FPS. The .22 versions come with a rifled barrel and fire .22 pellets only, at up to 450 FPS. Never fire steel BBs through a rifled barrel, because they can damage the rifling. Load each shot into one of the rifle's reusable metal cartridges.

Each rifle comes with 10 reusable cartridges for its caliber. For spares, the 1866 CO2 Rifle .177 Caliber Pellet Cartridges hold one .177 pellet each and fit only .177 barrels. The 1866 Pellet Cartridges (.22 Caliber) hold one .22 pellet each and fit only .22 barrels. Both come in packs of 10 and work with any standard airgun pellet of the matching caliber.

A rifled barrel spins the pellet for better accuracy. The 1866 CO2 Rifled Barrel Kits come in .177 and .22 caliber, and each includes a rifled barrel, a barrel adapter and 10 matching pellet cartridges. A .177 kit lets a smoothbore rifle shoot pellets more accurately, and a .22 kit lets you switch calibers. Installation is quick and reversible, but watch the installation video first. Kits are for pellets only and fit both the classic and Tactical models.

It uses two 12-gram CO2 cartridges at a time, stored under a cover in the buttstock. With the safety on, lift the cover, loosen the piercing screw with the Allen key stored inside, put a drop of silicone oil on each end of both cylinders and insert them necks out. Tighten until they pierce, without overtightening. Swap both when shots get quieter or start dropping, since nearly empty CO2 is the most common cause of jams.

They share the same internal system, lever action and 10-shot ejecting cartridges, and both come in .177 and .22. The classic 1866 CO2 has a faux wood polymer stock with a gold or black finish. The Tactical is all black with a polymer stock and an M-LOK compatible handguard for accessories. Every version includes a removable Picatinny rail section. The Tactical bundles add 12-gram CO2 and pellets.
