Frequently Asked Questions
Ruger AR556 AR 15 for sale
Is the Ruger AR-556 MPR good?
The AR-556 MPR is generally well-regarded for its price point. It's reliable for range use, home defense, and hunting. With a suggested retail price of $899 and street prices typically in the $650 to $700 range, it offers solid value. Whether it suits you depends on your intended use and budget.
What is the difference between Ruger AR-556 and 556 MPR?
AR-556 MPR features an 18-inch barrel versus the standard AR-556's 16-inch barrel. The MPR adds a rifle-length gas system, free-float handguard, improved trigger, and ships with a 30-round PMAG. The standard model suits home defense; the MPR is better for longer-range shooting.
What is the best ammo for the Ruger AR-556 MPR?
For range and training, 55-grain XM193 loads from Federal, Winchester, or PMC offer good value. For precision shooting, 75 or 77-grain match ammunition works well. The MPR handles standard 5.56 NATO reliably across most quality brands. M855 is compatible but skip it if accuracy is your priority.
What does Ruger MPR stand for?
MPR stands for Multi-Purpose Rifle. The Ruger AR-556 MPR features an 18-inch barrel, free-float handguard, and improved trigger, distinguishing it from the standard AR-556 and making it suitable for range shooting, hunting, and defensive use.
What is the best Ruger AR-15?
"Best" depends on your needs. The Ruger AR-556 MPR suits range shooting and hunting with its 18-inch barrel and free-float handguard, typically around $787. The standard AR-556 works well for home defense. The newer Ruger Harrier is also worth considering, reviewed as a potential new benchmark for entry-level ARs.
Is the Ruger 556 discontinued?
Ruger discontinued the SR-556 piston-driven line but replaced it with the AR-556, which remains in production. The AR-556 MPR variant is currently available from multiple retailers, typically priced around $787.
Does the Ruger AR-556 come with sights?
The standard Ruger AR-556 includes an elevation-adjustable A2-style front sight and a Ruger Rapid Deploy folding rear sight. An Optics Ready variant ships without sights. Check the specifications for the specific model you are considering before purchasing.
Where is the Ruger AR-556 made?
Ruger manufactures the AR-556 at its Mayodan, North Carolina facility, which opened in 2014. The AR-556 was the first firearm designed and built there, with all major components machined on site.
