We all know precision barrels for the AR-15 don’t come cheap and you generally get what you pay for. The Rainier Arms Select 5.56MM Barrel turns that convention on its ear. It offers features and performance that can usually only be found on barrels that cost twice as much.
These barrels feature polygonal rifling which is a functional feature that is usually reserved for more expensive barrels. Polygonal rifling forms a tighter seal around the projectile which leads to higher velocities, and, because it lacks the grooves of typical cut rifling, it tends to suffer from less copper and lead build up. Barrels with polygonal rifling also tend to last longer than their cut rifling counterparts.
Other features include:
- Bead blasted stainless or black oxide finishes
- 416R stainless steel construction
- 1×8 Twist
- M4 feed ramps
- 5.56 chamber
- Midlength gas system
- The Rainier Arms Select 5.56MM Barrel
- 16″ length
The Rainier Arms Select 5.56 Barrel offers some pretty staggering features for a barrel that sells for just $189.95! Check out these barrels at the Rainier Arms webstore or visit the Rainier Arms Industry Forum on AR15.com.
