Frequently Asked Questions
What barrel diameter does this gas block fit?
This gas block is bored to .750 inches, fitting the most common AR-15 barrel diameter at the gas block seating area. Always measure your barrel at the gas block location before ordering — common diameters are .750, .875, and .936 inch depending on barrel profile.
What is a set screw gas block?
A set screw gas block uses screws that press directly against the barrel surface to hold the gas block in place. Degrease both the barrel journal and set screw tips thoroughly before installation. Apply thread-locking compound to the set screws and torque to manufacturer specifications to prevent loosening under recoil.
How do I install this gas block?
Remove the existing front sight base or gas block, degrease the barrel journal and gas block bore, align the gas port in the block with the gas port in the barrel, and torque the set screws to manufacturer specifications with thread-locking compound applied. Confirm the gas tube seats and routes correctly to the upper receiver before completing the build.
