The Sig Sauer Airguns AIRMPX177G2 revolutionizes the concept of CO2 rifles, just as the SIG MPX altered the landscape of modern pistol caliber SBRs. The air rifle accurately retains the weight, balance, and controls of the original model, ensuring a realistic practice experience. It is chambered in .177 pellet and houses an 8\" rifled steel barrel. This not only enhances the accuracy but also makes training more readily available.
