    TriArc TSR-15 Service 10.5" TRACK 5.56MM Complete Upper with 9.5" TRILOK M-LOK Rail


    The TriArc TSR-15 Service 10.5" TRACK 5.56MM Complete Upper with 9.5" TRILOK M-LOK Rail (TSR-15-S-UPPER-105-556-BLK) has a clean finish and perfect for an AR pistol or SBR setup. The TSR-15 Service Upper comes with a NP3 coated BCG and a Radian LT ambi charging handle. The upper receiver is forged from 7075-T6 aluminum and the 9.5" TRILOK rail has seven sides for attachments in the M-LOK format.


    The TSR-15 upper is built around TriArc’s 10.5” 4150 Chrome Lined TRACK barrel. This particular barrel is a hybrid of standard and polygonal rifling that reduces deformation of the bullet. Essentially, the bullet moves through the TRACK barrel in a straighter line, which increases the overall accuracy. The barrel is chambered for 5.56MM, has a 1:7 twist rate, and a NP3 coating on the barrel extension to enhance the barrel's resistance to wear. Additionally, the barrel features a balanced profile which enables heat to disperse more evenly.
