Rainier Arms 5.56 NATO AR-15 Barrel - 6.75" Satin (Contract Overrun)

Occasionally we have orders for custom guns that leave us with spare parts at the end of the process. In those situations, we often have products in non-standard configurations that, while functional, aren't going to be carried in the future. This is the case with our Contract Overrun 5.56mm 6" barrels. These are machined out of the highest quality blanks that you expect from Rainier Arms. However, since these were made for a custom project there is no accuracy guarantee on this barrels due to the barrel length, ammunition variance, build components, etc. Features: Stainless Steel Match Grade Blank Length: 6.75" Twist: 1:7 Thread Pitch: 1/2x28 .750 Gas Block Seat 5.56 NATO Chamber Pistol Gas System (Gas Tube Not Included) M4 Feed Ramps Proprietary Contour Beat Blasted Finish Weight: 14.9 oz
