Geissele Automatics Rifle Lowers for Sale

Geissele Automatics, LLC of the United States built its presence in AR-15 rifle lowers by 2019 with Super Duty lower receivers, later adding stripped lowers and receiver sets, and in 2026 introducing the fully ambidextrous MOD1-A lower. Their lowers are forged 7075-T6 with an enhanced flared magwell and are often paired with Geissele’s upgraded lower-control parts; the 2026 MOD1-A configuration adds a distinctive fully ambidextrous control scheme that includes a dust-cover-actuated right-side bolt lock and release.
