Product Description
Osprey AR15 drop ins are ready to go.
Options available are 18 and 20 inch finished lengths with 0.750" gas boss diameters. All barrels come standard with 5/8-24 muzzle threads. Barrels come with an alignment mark under the gas port for easy assembly.
As usual with all the Osprey pre-fits these are honed and lapped, double normalized (stress relieved) stainless and 100% CNC machined. For accuracy reasons we recommend clamp on style gas blocks, not set screw style. The gas port sizes are setup for optimal performance with unsuppressed systems. If using a suppressor it is recommended that an adjustable gas block or adjustable gas key be installed to aid in tuning the rifle system.
All gas systems in the ARC series are Rifle+2
