Every AR-15 fire control group lives or dies by two tiny pins, and this 10-pack from White Label Armory keeps you stocked. These are the pins that hold your hammer and trigger in the lower and let them pivot every time you break a shot, so getting them right matters more than their size suggests. Each one is turned on precision Swiss CNC machines and cut to standard mil-spec 0.154-inch dimensions, which is the diameter that plays nice with the vast majority of AR-15 lowers and two-piece triggers on the market.
The pins wear a phosphate coating that helps fight corrosion and takes a little of the friction out of the pivot, so your trigger and hammer swing smoothly instead of dragging. Because they are held to tight tolerances, you get a consistent fit without the sloppy play you sometimes find in bargain-bin pins. All ten are 100 percent American made, which is a point of pride for White Label and something a lot of builders look for when sourcing internals.
A standard AR-15 uses two of these pins per rifle, so this pack covers five complete builds or leaves you with a solid stash of spares. Pins are exactly the kind of small part that walks off the bench, rolls under the safe, or gets buggered up during a hammer-and-punch install, so having backups on hand saves a trip and keeps a project moving. Builders, hobbyists, and anyone doing regular maintenance on multiple ARs get real value out of buying in bulk.
Installation is straightforward with a bench block, a set of punches, and a little patience. These are a great match for standard mil-spec fire control groups and make a smart addition to any parts drawer or armorer's kit.
These are standard mil-spec pins measuring 0.154 inches in diameter. That size is the industry norm for AR-15 hammer and trigger pins and fits the large majority of mil-spec lower receivers and two-piece fire control groups. If you are running a receiver machined for the older Colt large-pin size, you would need a different pin.
A standard AR-15 uses two fire control group pins, one for the hammer and one for the trigger. That means this pack outfits five complete builds, or gives you a full set plus a healthy pile of spares. Pins are easy to lose or damage during installation, so the extras tend to come in handy.
These pins are built for standard mil-spec two-piece fire control groups. Many drop-in and cassette triggers ship with their own pins or use a specific retention setup, so check what your trigger requires before installing. For a traditional hammer, trigger, and disconnector build, these are exactly what you want.
A bench block to support the lower, a set of punches, and a small hammer will get the job done. Take your time seating the pins and support the receiver so you do not mar it. The phosphate finish and tight tolerances help them slide in cleanly without excessive force.
