Anyone who has assembled an AR-15 lower knows the story: you set a detent on the bench, reach for the buffer retainer, and by the time you look back one of those tiny pins has pinged off into the void. Strike Industries built this PRO pin kit to end that headache for good. Instead of a single set of parts, you get bulk quantities of the small hardware that holds a Mil-Spec lower together, so a lost detent or a mangled roll pin never brings your work to a halt.
This is the larger PRO version, not the single-build kit. Inside you get 20 takedown pins, 20 pivot pins, 40 trigger/hammer pins, 20 buffer retainer pins, 20 bolt catch plungers, 20 bolt catch roll pins, 40 takedown/pivot pin detents, and 20 safety detents. That is enough to service or build a stack of lowers before you ever need to reorder. Every piece is cut to Mil-Spec dimensions and finished in a low-glare matte black that blends right in with standard AR-15 components.
Armorers, FFL assembly benches, and home builders working through more than one lower are the sweet spot here. If you build in any kind of volume, staging a full set of these consumables on the shelf keeps production moving instead of stopping to source one four-cent detent. Builders who like keeping spares around for the inevitable oops also get a lot of mileage out of it, since these are exactly the parts that walk off and disappear.
These are AR-15 parts through and through, sized for Mil-Spec lower receivers. The bolt catch roll pin, pivot pin, and takedown pin are not compatible with AR-10 lowers, so keep this kit dedicated to your AR-15 platform work and you will be in good shape.
The standard kit gives you one of each pin and detent, which covers a single lower build. This PRO version stocks bulk quantities, like 20 takedown pins and 40 trigger/hammer pins, so it is meant for armorers and anyone building or servicing multiple lowers. If you only need to finish one lower, the smaller kit will do, but the PRO kit saves you constant reordering.
No, this kit is dimensioned for AR-15 Mil-Spec lower receivers. Strike Industries specifically notes that the bolt catch roll pin, pivot pin, and takedown pin are not compatible with AR-10 lowers. Keep this kit dedicated to your AR-15 platform work.
Basic AR-15 build tools help a lot, like a roll pin punch set and a bolt catch or pivot pin installation tool. The detents and takedown pins can often be seated by hand or with light punch work, but roll pins go in cleaner with the right punch. Having a proper punch set keeps you from marring the finish on your lower.
Yes, the pins and detents are cut to standard Mil-Spec dimensions and follow industry sizing, so they drop into standard AR-15 lowers as replacements. The matte black finish also matches typical factory AR-15 hardware. Feedback on these parts consistently points to solid quality for the price.
