摘要： An inexpensive generally retrofitable drop-in cartridge-unit of light-weight pneumatic-cylinder design for replacing the conventional metal/compression-spring member housed within the frame of a gun, thereby providing significantly smoother, quiter, more rapid, and more reliable cyclic-action upon firing of the gun. The preferred embodiment cartridge-unit is internally configured whereby a near constant spring-load rise is provided as the bolt-action slides aftward, thereby effectively spreading resultant recoil-action inertial-kickback more evenly throughout the bolt-travel. Hence, substantially reducing disturbing kickback, enabling a more rapid succession of shots per given shot-grouping owing to the shooter's improved recovery-time. Various iterations are set forth, including those of single, double, and tripple telescopic-action, and a hybrid/metal-pneumatic variant, as well as generic-variants providing manual and automatic pneumatic-pressure adjustment. Plus, a further iteration facilitating manual adjustment of air-gun thrust-pressure.
摘要翻译： 一种用于更换容纳在枪架内的传统金属/压缩弹簧构件的轻便气动气缸设计的便宜的普遍可改型的落入式卡盒单元，从而提供显着更平滑，快速，更快速和更可靠的循环 枪的射击。 优选实施例的卡盒单元是内部配置的，由此当螺栓动作向后滑动时提供接近恒定的弹簧载荷升高，从而在整个螺栓行程中更均匀地有效地展开所产生的反冲作用惯性反冲。 因此，由于射手改进的恢复时间，大大减少了令人不安的反冲，从而能够更快速地连续射击每个射击组。 阐述了各种迭代，包括单一，双重和三重伸缩作用，以及混合/金属 - 气动变型，以及提供手动和自动气压调节的通用变体。 此外，进一步的迭代，便于手动调整气枪推力。
