Brownells 75th Anniversary - A Shooting Heritage

The Easy-To-Install Upgrades That ll Make Your AR Easier To Operate Safely

The Battle Arms Enhanced Lower Parts Kit contains three components that will make operation of your AR-15’s controls faster, easier, and smoother, so you’ll have better control over your rifle, especially in speed-critical situations. This kit contains 3 important Battle Arms parts:

BAD-E4S-IC Enhanced Single-Side Safety Selector has the deeply textured, slightly oversized paddle of the ambidextrous "BAD-ASS" selector, but only on the right side. For shooters who do not need ambidextrous controls, this selector helps them engage/disengage the safety quickly. This is a 2-position semi-auto safety with 0 deg. & 90 deg. positions.

BAD-EMC-IC Enhanced Magazine Catch is more robust and lighter than the mil-spec AR-15 mag catch. Its shorter post causes the mag release button to sit lower in the receiver, making it less likely you’ll accidentally bump it and dump your mag at the wrong moment. Compatible with the standard mil-spec mag release button, as well as Battle Arms BAD-EMR, BAD-EMMR, and similar buttons.

BAD-EBC-IC Enhanced Bolt Catch offers a much larger contact surface than the standard mil-spec part, so it’s easier to locate the control and release the bolt when you’re under stress. Pronounced serrations running in two directions provide a non-slip contact surface, while the raised T-shaped heel aids in secure bolt lock back. Compatible with Norgon Ambi-Catch. Bolt catch ONLY - roll pin, detent & spring NOT included.

All three components share the same sturdy construction to ensure years of reliable service:

  • Easy-to-install drop-in replacements for factory parts
  • 8620 carbon steel (investment cast), heat-treated for hardness
  • Matte black phosphate finish matches most black-anodized receiver
  • Fit standard mil-spec AR-15 lower receiver

This Enhanced Lower Parts Kit consists only of these three parts, so it’s not a complete LPK with all the small internal parts, but don’t worry, Brownells sells a number of those. What the Battle Arms kit will do is improve your ability to operate your AR-15 quickly, reliably, and safely.
