Semiautomatic firearm having lighter cocking action |
摘要 |
An improved semiautomatic firearm is provided comprising as assembly which reduces the effort of cocking the firearm or loading a first cartridge. A spring tube contains an inner recoil spring which is employed only during cycling of the firearm when firing. For initial cocking purposes, the inner recoil spring is bypassed in favor of a lighter outer spring which is selectively engaged by the user. When the inner recoil spring is engaged, both inner and outer springs are employed without adversely affecting the recoil dynamics of the firearm. |
