Griffin Armament Primo Low Profile AR-15 Gas Block - Set Screw - .750"
Details
The Griffin Armament Primo Low Profile AR-15 Gas Block is machined from 416R stainless steel for a durable, corrosion-resistant gas block that's ready to be pinned or run with set screws alone. Built for .750" barrels, it fits most AR-15 barrels and some AR-10 barrels, giving builders flexibility across platforms and barrel manufacturers.
Features:
- 416R stainless steel construction
- QPQ Nitride finish
- .750" inner diameter
- Low profile design
- Drilled for optional barrel pin installation
- Knurled grip cup point set screws
- Includes hex key and gas tube roll pin
- Compatible with some AR-10 barrels
- Backed by Griffin Armament's perpetual lifetime warranty
Two set screws with knurled grip cup points bite into the barrel for a secure hold, and the block is pre-drilled if you'd rather pin it to the barrel for an extra margin of security. The QPQ nitride finish over 416R stainless steel gives the block strong resistance to heat, corrosion, and wear, and Griffin backs it with a perpetual lifetime warranty against manufacturing defects, so it's a part you install once and stop thinking about for the life of the rifle.
Griffin Armament builds suppressors, muzzle devices, and rifle components in the United States, backing its parts, including this gas block, with a perpetual lifetime warranty.
