  • Torx screw torque value should be approximately 5 In-Lbs. Do not over tighten.
  • Some fitting may be required with Geissele Triggers on the 50° Short-Throw side.
  • BAD-ASS-ST Short Throw Safety Selector will not fit in "standard" AR-style lower receivers designed for 0°-90° throw safety selectors. A relief cut on the left side of the receiver safety selector hole is required to allow the safety pin block device on the BAD-ASS-ST center to pass through. The safety pin block is there for your safety so it cannot be installed on a "standard" AR and allow the safety selector lever to point ambigously between SAFE and FIRE. "Short-Throw" compatible lower receivers with safety pin relief cut and 45° to 90° FIRE marking (such as the BAD-15 Forged Lower and BAD556-LW Lower Receivers) are required for proper installation. Any modification to the safety selector will render the warranty null and void

Accuracy Guarantee

Guaranteed to Perform

We are committed to providing products that meet, or exceed, the expectations of our most discerning customers. We stand behind that commitment. From the moment you unwrap one of our barrels, as you configure it with your receivers and handguards, and as you fire it on the range or in the field, we want you to experience the unique elegance and uncompromising quality that we craft into every one of our barrels.

We also stand behind our commitment to performance. All Ballistic Advantage barrels are guaranteed to give sub Minute of Angle (MOA) accuracy with match grade ammunition.1

If you are not completely satisfied with the form, finish, and fit of any of our barrels, please visit Contact to discuss your concerns. If you find your BA barrel is not performing at the high standard of sub MOA accuracy, please first consult our Troubleshooting Guide on our website. If you need further assistance please visit Contact. Usually, our armorers are able to resolve any issues over the phone. If the issues are not resolved we will ask that the barrel be sent to us for inspection.2 We will either correct the problem or replace the barrel, or if the customer prefers, we will reimburse the purchase price of the barrel.

1 We define sub MOA as a group size of 1 inch or under at 100 yards with a 3 shot magazine fed group, or 5 shot single loaded group.

2 The customer is responsible for the initial return shipping costs of the barrel. If any defects are found, BA will reimburse the shipping costs and either replace or refund the original purchase price of the barrel.
