Custom Piece – M110 Semi-Automatic Sniper System SASS SR 25 sniper rifle – 3D Print for LEGO minifigure

A black, toy semi-automatic sniper rifle accessory for a minifigure, modeled after an M110 SASS or SR-25. It features a telescopic scope, a short sound suppressor (as indicated by “短消音”), and a vertical foregrip.”

Specifically, this toy gun most likely represents the M110 Semi-Automatic Sniper System (SASS). The M110 SASS is a military version of the Knight’s Armament Company (KAC) SR-25. Key visual cues are the AR-10-style receiver, the railed handguard, the presence of a scope, and the suppressor. The filename “M110短消音” translates to “M110 short silencer/suppressor,” which matches the accessory. The vertical foregrip is also a common attachment.

While visually very similar and based on the SR-25, the M110 designation usually refers to the specific system adopted by the U.S. military. So, it’s best identified as an M110 SASS, though it shares its core design with the SR-25.
