Pro Arms Replacement Spring Set – TMG17 Gen 5 MOS

Springs are the heartbeat of any gas blowback pistol. Over time, repeated compression weakens factory springs, leading to reduced gas efficiency, sluggish slide cycling, and inconsistent trigger breaks. The Pro Arms Replacement Spring Set for TMG17 Gen 5 MOS is precision-engineered to return your Tokyo Marui G17 Gen 5 to factory performance standards—or improve upon them.

Key Features

• Direct fitment for Tokyo Marui G17 Gen 5 MOS GBB pistol

• Restores reliable slide cycling and gas efficiency
• Improves trigger reset speed and consistency
• Cost-effective alternative to full pistol replacement

Real-World Use Cases

Whether you’re running CQB skirmishes, outdoor range sessions, or casual target shooting, worn springs will eventually compromise performance. Field stripping your TMG17 Gen 5 MOS reveals the culprit: a sagging recoil spring or weakened hammer spring. This set lets you perform a full spring refresh in minutes, extending your pistol’s competitive lifespan and maintaining the snappy performance that makes Tokyo Marui pistols so reliable.
