The ASG STI Duty One is a skirmish-ready CO2 airsoft pistol that excels on the battlefield. This semiautomatic gun has a working hammer and its own individual serial number for added realism. The blowback recoil is both responsive and impressive and compares favorably with other CO2 blowback pistols on the market. The pistol is powered by a standard 12-gram CO2 cartridge and features a full metal slide, 16 rd magazine and a shot velocity of 410-430 fps (using .20g BBs). Attach a flashlight or red dot sight on the tactical rail underneath the barrel for increased visibility & quick target acquisition. The adjustable hop-up system can also be dialed in for solid long range accuracy needed to excel on the field.

    • manideepsai from India asked:

      what can i get with this package

      • Thomas from USA asked:

        The ASG STI duty one pistol is listed as 6mm bore. There is a clip by ASG for STI duty one but it does not list a bore size. Do you sell the 6mm spare magazines for the 6mm bore pistol? If not, can I order some?

        • Erika from U.S. Virgin Islands:

          We do not carry a magazine for this pistol
