Police trade in AR15 gets CHEAP upgrades. SUB $1000 ALL IN!
This video details the ergonomic and aesthetic upgrades made to a police trade-in Rock River L15 AR-15, aiming for a sub-$1000 total build cost. Key modifications include adding a BCM forward grip with goon tape and Magpul grip panels to mitigate the harsh texture of the original Surefire quad rail. A Trijicon ACOG RX01 optic is installed for its battery-free, tritium-powered illumination and robust build, fitting the retro aesthetic of the rifle.
