Battle Arms Development produces the Enhanced Takedown and Pivot Pins Set (EPS) for AR15 users who require the best in every single part of their rifles.

The EPS makes disassembly easier than ever. The enlarged pin tips make it a breeze to push the pins through from the left side of the rifle without creating a snag point. The pin heads are knurled around the sides and tapered inward to form a superior gripping surface.

Another useful feature is the presence of cone-shaped dimples on both sides of the takedown pin, which prevent pin punches from sliding off and scratching the receiver during disassembly or reassembly. The EPS is also fully compatible with ambidextrous safety selectors.

    I bought these for my son's first AR15. I use them also, that's why I recommend him get the set. I have a set of A Strike Industry ones, but they dont compare the B.A.D. set

  • Buy These from Wing Tatical

    These are nice but fit poorly. Learn from me - Buy these from Wing Tactical so you can return them if you don't like the way they fit. The bottom of the pivot pin head does not fit flush when you push it all the way in and it sticks out clearly leaving a gap and looks bad. This was on both a Spikes and an Anderson lower. I contacted B.A.D. and they wrote, "We will inspect the pins to see if it is out of spec and if it is in spec, there isn't much we can do since you purchased the product from.......... and you have received what you paid for."

  • BAD-EPS will be on all my builds

    Typical battle arms quality and fitment. These pins look and perform flawlessly. I will definitely be recommending these pins to anyone completing a build or just looking to upgrade their current AR
