The Riflespeed adjustable gas block, .625 journal, 2.4-inch assembly, lets you tune the gas on an AR-15 or AR-10 without tools. A numbered control knob with a tactile click for every setting makes each adjustment repeatable, so you can return to a known setting for suppressed fire, different ammunition or changing conditions. Riflespeed identifies this length as model RS6224, and the last two digits give the assembly length. It requires a straight gas tube, which is not included.

Key Specifications

• The journal diameter is .625 inch, so it fits barrels with a gas block journal of that size.
• The assembly length is 2.4 inches, which is the dimension to check against your handguard and muzzle device.
• Adjustment is tool-free through a numbered control knob with tactile clicks, so settings are easy to read and repeat.
• A rotation stop keeps the knob from turning far enough to unintentionally disassemble the control.
• It requires a straight gas tube, either Riflespeed or an equivalent, and the tube is not included.

Do I need tools to adjust it? No. The control knob is adjusted by hand, with numbered settings and a tactile click at each one.
