What Is a Foldable Rifle?

A foldable rifle is a firearm designed with a collapsible or folding stock, allowing it to become significantly more compact for storage or transport. Unlike traditional rifles with fixed stocks, foldable rifles can reduce their overall length by up to 50%, making them ideal for concealed carry, tactical operations, or situations where space is limited.

The most advanced models, such as the FoldAR, take this concept further by incorporating multiple folding points—not just at the stock but also between the upper receiver and handguard. This innovation enables the rifle to fit inside a standard backpack while still maintaining full-sized rifle performance.
