The Remington Nylon 66 is a semi-automatic .22 Long Rifle rifle introduced in 1959 by Remington Arms. It was a groundbreaking firearm that used a synthetic stock made from DuPont Zytel nylon instead of traditional wood. The stock carried most of the structural load, allowing a lighter overall weight of about 4 pounds. The Nylon 66 featured a 19.5-inch barrel with a tubular 14-round magazine. Its chemical-resistant, scratch-resistant stock was available in distinctive colors including Mohawk Brown, Seneca Green, and Apache Black. The Nylon 66 was one of the first commercially successful firearms to utilize synthetic materials on a large scale.

The Calico M900 is a semi-automatic carbine chambered in .22 Long Rifle, produced by Calico Light Weapon Systems as a rimfire companion to the M100. It uses the same distinctive helical-feed magazine mounted above the receiver, available in 50 or 100-round capacity. The M900 features a blowback action and a full-length Picatinny rail on top of the receiver. Its lightweight construction and massive magazine capacity made it popular for plinking and competition. The M900 was one of the few rifles capable of firing 100 rounds of .22 LR without reloading. It was also produced in a select-fire variant.
