SIG SAUER MPX .177 CO2 Air Rifle, 30-Round RPM Belt, 8-Inch Rifled Steel Barrel, Black
This SIG SAUER MPX .177-caliber CO2 air rifle is a factory-new example of SIG's training analog to the centerfire MPX, featuring AR-style controls and a selector lever safety. It uses an 88/90 g CO2 cylinder housed in the buttstock and the RPM (Rapid Pellet Magazine) 30-round belted feed system. A continuous Picatinny top rail, polymer handguard with accessory rail sections, and flip-up adjustable sights round out a feature set aimed at realistic handling and fast follow-up shots.

Powered by an 88/90 g CO2 cylinder tucked cleanly into the buttstock, the MPX Air delivers true semi-automatic operation for rapid strings. SIG's RPM (Rapid Pellet Magazine) belted system provides a 30-round capacity and smooth feeding for efficient training or plinking.
A rifled steel 8-inch barrel supports .177 (4.5 mm) pellets, while the black synthetic, non-folding stock and polymer handguard are built for durability. The rifle includes a continuous Picatinny top rail and accessory rail sections on the handguard, plus flip-up adjustable front and rear sights for flexible sighting options.
Dimensions closely mirror a compact carbine format, with a 25.75-inch overall length and a 6.2-pound weight for familiar handling. Controls are AR-style, including a selector lever safety, reinforcing its role as a practical training companion to the centerfire MPX.
Factory packaging states up to 600 fps, while the current SIG SAUER product page lists up to 450 fps. This example is the black-finished variant with CE mark and SIG part number AIR-MPX-177-88G-30-BLK.
