More Improved & More Reliable Bolt Catch Release For AR-15

The Phase 5 Weapon Systems AR-15 Extended Bolt Release V3 is the more improved one-piece replacement part for the mil-spec bolt catch found in all AR-15/M16 lower parts kits. This bolt release helps in clearing jams more efficiently and reduces unnecessary hand movements by extending the lever into the trigger well for access on the right side of the weapon.

It is compatible with all mil-spec AR-15/M16 receiver sets as well as many billets, side charging, and even left-handed weapons.

Heat-treated, High-Strength Alloy Steel

The Phase 5 Weapon Systems AR-15 Extended Bolt Release V3 improvements include grip serrations to the elbow and the end of the extended bolt release lever, a larger index finger tab for bolt release, and an improved magazine follower catch that aids in quicker and more efficient magazine reloads.

Compatibility: The EBRv3 is compatible with nearly all AR-15/M16 platform rifles and pistols. This includes many sides charging upper receivers, and billet receivers that cannot accept a bolt-on Extended Bolt Release.


  • Heat-treated, high-strength alloy steel, same as a mil-spec bolt catch.
  • Secure patented monolithic design, direct replacement component, no screws to come loose.
  • Low profile bolt catch, fits many aftermarket billet upper receivers and most side charging upper receivers.
  • Grip serrations added to elbow and end of Extended Bolt Release lever.
  • Improved magazine follower catch.
  • Larger index finger tab for bolt release.
  • Made in the U.S.A


  • Material: 8620 Carbon Steel
  • Weight: 0.7 oz.

bolt release

awesome work pretty good thank you

Andrew Thornton

Very well made but dint fit what I wanted it for.

Nearly There but Unusable

for a product that is on its 3rd version I would think the designers would have tested it a bit more. In using it on a Aero M4E1 Lower it sat to close to the trigger (drop in CMC flat trigger) that my finger was not able to fit without hitting the bar. If it followed the profile of a magpul BAD Lever it would be the perfect addition. Its light and strong but due to it being way to close to the trigger I am giving it 1 star.

AT3 was awesome in their shipping and help in returning this item.

So sorry to hear that the item did not meet your expectations, Brian. We forwarded your feedback to the manufacturer, we appreciate you taking the time out to leave this review.
