IMPACT PRECISION NBK MEDIUM ACTION

The Impact Medium Action NBK brings the proven design of the Impact 737R and Short Action NBK into a lighter-weight precision hunting action designed for your next hunting rifle. The Medium Action NBK utilizes the same barrel tenon and headspace specifications as the 737R and can readily accept 737R pre-fit barrels.

The one-piece bolt is designed with proper geometry and clearance for smooth operation under field conditions. Fluting on the top and sides of the bolt body helps carry dirt away, while the smooth bottom portion is designed for smooth cycling. A black carbon nitride finish improves operation by increasing surface hardness and lubricity.

The Medium Action NBK features an EDM-cut raceway and hardened, finish-machined steel action body. Its 75-degree, two-lug bolt design features interchangeable bolt knobs, while the .700-inch diameter bolt uses a Mini M16 extractor.

The action accepts Remington 700 triggers and is cut for AICS and Hawkins Hunter magazines. A trigger hanger allows simplified field maintenance, while the split integral 20 MOA rail and integral recoil lug provide a rigid foundation for a precision hunting rifle.

The Medium Action NBK is specifically not compatible with BDL-style hardware.
