Semiauto Open-Bolt MAC-10 (They Made More than 100,000 of These)
This review details the RPB Semiauto M10 SAP, an open-bolt pistol developed as a cheaper alternative to the full-auto MAC-10. It highlights the firearm's simple blowback operation, unique RPB 'Cobra' logo, and the ATF's 1982 ruling that reclassified such designs, leading to production cessation. The video also contrasts the semi-auto trigger group with its full-auto counterpart, noting the ease of conversion.
