The Armaspec ARM137-BLK takes the standard AR-15 takedown and pivot pin and adds three practical features that make installation and field-stripping noticeably easier. The convex head can be pushed in from any angle — useful when you don’t have a punch perfectly lined up. The extended concave tip gives you a solid contact point for removal using a flat-head, a bullet tip, or anything pointed. The EZ-Set hole lets you hold the detent in place while seating the pin, eliminating the common frustration of the detent springing loose mid-install. Both pins are steel with a black nitride finish for corrosion resistance.
What’s Included in the Armaspec ARM137-BLK Set
- 1x enhanced takedown pin — steel, black nitride, convex head, EZ-Set hole
- 1x enhanced pivot pin — steel, black nitride, convex head, EZ-Set hole
What the Armaspec Enhanced Pin Set Does Not Include
Detents and springs are not included. The EZ-Set hole is designed to assist with detent installation, but the detents and springs themselves must be sourced separately. No bolt carrier group or charging handle is included.
