Rock River Arms LAR-15M 17 HMR | 18-inch | 10rd | 17HMR1325

The Rock River Arms LAR-15M is a purpose-built modern sporting rifle chambered in .17 HMR, configured with an 18-inch threaded nitride steel barrel and a 15-inch M-LOK free-float handguard. It ships with a Magpul SL-K synthetic stock, Magpul MOE-style pistol grip, a two-stage RRA Ultra Match trigger, a detachable 10-round magazine, and a case. For a compact, reliable optic under $1,000 that pairs well with this carbine, consider a Vortex Crossfire II 2-7×32 — it provides a clear sight picture and enough magnification for typical varmint work and range use.
