To select the correct length kit use the following measurements :

• Pistol: 4.846″ from barrel extension to shoulder
• Carbine: 7.866″ from barrel extension to shoulder
• Mid: 9.866″ from barrel extension to shoulder
• Rifle: 13.241″ from barrel extension to shoulder
• For 300BLK we only recommend a Pistol Gas Length and a Low Mass Carrier for optimal performance.

• Adams Arms recommends using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.

  Micro Gas Blocks should have the set screws torqued to 55-60 in-lbs
