A Lot Of Love For The Rock River Arms Rifle

This reviewer has a lot of love for the RRA rifle.
Rock River Arms’ new Fred Eichler Series LAR-15 Predator joins a growing number of AR-platform rifles and carbines specifically configured for the serious coyote and bobcat hunter. Sporting a medium-weight 16-inch stainless steel barrel, it represents the top of Rock River’s current four-model line of ARs specifically configured for coyote pursuit.
It was developed and field tested with the extensive help of Fred Eichler, host of the television show Predator Nation. The Fred Eichler series embodies not only the basic functionality of the AR platform that has made it so widely popular with predator hunters in the first place but also an impressive set of individual custom touches that elevate it to a pack leader among this category of guns.
Anyone who is at all familiar with AR-15 rifles understands why they are virtually perfect predator hunting tools and why predator hunters were early leaders in the mass migration of AR-platform carbines and rifles from the world of tactical, military and law-enforcement applications into full status as “modern sporting rifles.”
This is an interesting article, but this bit caught my eye.
There’s a lot of misunderstanding out in the world about the relative “inherent accuracy” of long barrels and short barrels. In reality (all other things being equal), short barrels are inherently more accurate than long barrels because they are stiffer, don’t flex and vibrate so much while bullets are passing through their bore and experience less muzzle displacement shot-to-shot due to variable harmonics.
In other words, the vibration amplitude isn’t as great with a shorter barrel. This is a very interesting point, and one that I’ve overlooked before. Although it could also be observed that the longer barrel is necessary at times to get the full potential out of the muzzle velocity of the round.
In the picture above I have to think they are shipping that rifle with a Pmag or Hexmag if you bought it today.
