Faxon Firearms Match Series Gunner 1:5T Barreled 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.

Features:

• 300 BLK (300 AAC Blackout), 7.5" Gunner-profile pistol-length Match Series barrel, 1:5 RH twist, 5R button rifling, 5/8x24 muzzle with a recessed crown
• 416R stainless steel barrel, salt-bath nitride (QPQ), NP3-coated barrel extension
• Faxon patented adjustable .750" 3-screw low profile gas block with 14 settings, pistol-length gas tube
• Faxon MuzzLok Plan B flash hider, 5/8x24, .375" bore, 17-4 PH stainless
• Faxon Streamline aluminum 7" free-floated M-LOK handguard
• Faxon Enhanced Forged AR-15 upper receiver with a forward assist and dust cover
• Barreled upper assembly: it does not include a bolt carrier group, charging handle, lower receiver, or magazines

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.
