The LRR (full name Long Range Rifle)is the British designation of the famous Artic Warfare rifle, added as of 1.9.0 to the Dayz Mod.
The LRR is currently one of the most rare and powerful weapons found in the Dayz Mod. It has the longest range and zeroing of any weapon in the mod, capable of hitting targets over 1000 meters away and being zero-able to 1400 meters. While it is still not as powerful or as ranged as the now removed AS-50, it still outclasses most rifles in terms of damage and range.
The LRR however has 2 major drawbacks that reduces its effectiveness, it's magazines and sound. The .338 ammunition is very rare, with both magazines being uncommon and only containing 5 rounds. A survivor can quickly find that most of the Dayz sniper rifles are more useful then the LRR. Nearly all the other sniper rifles have more common ammunition, especially the DMR and other NATO bolt action rifles. Even the MK-48, the original rarest weapon, has more common ammo. Added to this is that in Chernarus sight lines rarely extend past 800-1000 meters. The LRR is also a very loud weapon, both it's distinctive shot and cocking sound can be heard over great distances. When you fire, you can bet every survivor and bandit in the area will be hunting for you and your shiny LRR.
