Details & Specs

Olympic Arms® UMAR-22250 .22-250 Semi-automatic Rifle

That's right... an AR-15 that shoots .22-250 cartridges. And made to be accurate, round after round. Take a look and you'll see what sets this Olympic Arms UMAR above the rest.

  • Modified UMAR AR-15 lower receiver magazine well. Designed specifically for the UMAR magazines to accept the venerable .22-250 caliber and long WSSM loads.
  • Threaded bolt catch hole: designed for a quick and easy change of your bolt catch between standard 5.56 magazine and the UMAR magazines
  • All modified UMAR lower receivers can also readily accept every standard AR-15 upper and caliber option. The UMAR lower is applicable to all AR-15 calibers from .22 LR and 5.56 NATO, to the WSSM and .22-250 calibers. Just swap the upper, the magazine and the bolt catch (if needed)
  • 24" button-rifled bull barrel
