Faxon Firearms Match Series Gunner 1:5T Complete AR-15 Upper Receiver - .300 BLK - 7.5" - Suppressor Ready

The Faxon Match Series 7.5" Gunner .300 BLK 1:5T upper is a suppressor-ready upper with a 416R stainless Match Series barrel in a 1:5 twist, an adjustable .750" gas block, a MuzzLok Plan B flash hider, and a 7" M-LOK handguard, in barreled and complete versions.

• Faxon patented adjustable .750" 3-screw low profile gas block with 14 settings, pistol-length gas tube

• Does not include a lower receiver, buffer and spring, magazines, or a suppressor

The 1:5 twist helps long, heavy subsonic bullets stay stable from a short barrel, and 5R rifling is gentler on jackets than sharp-shouldered rifling. The adjustable gas block handles the difference between subsonic and supersonic loads, with or without a suppressor. Match Series barrels are 416R stainless, button rifled, stress relieved, and salt-bath nitrided, and each one is 100% magnetic-particle inspected, air-gauged, and headspace checked.
