Building an AR-15 from a stripped lower is one of the more satisfying weekend projects out there, but it only goes smoothly when you've got every tiny spring, detent, and pin ready to drop in. The Aim Sports ARCLPK Complete Lower Parts Kit rounds up all those pieces into a single package so you're not hunting for a missing bolt catch spring at the worst possible moment. It's a straightforward mil-spec style kit built to fit standard AR-15 lowers, and it comes in a clean matte black finish that blends right in with the rest of your build.
The kit ships with the trigger and hammer assembly, safety switch, bolt and catch, front and rear receiver lock pins, magazine release assembly, and trigger guard. Rounding it out is a black polymer A2-style pistol grip, so you've got a functional grip in the box without needing to source one separately. That said, plenty of builders swap the A2 grip for an aftermarket ergonomic option down the road, and this kit gives you a solid starting point either way.
Installation is a rite of passage for AR builders, and this kit plays nice with common bench tools like a vise block and a set of roll pin punches. The springs and detents are the fiddly part on any lower build, so take your time with the bolt catch roll pin and the buffer retainer. If you've done one before, you'll knock this out in an afternoon. If it's your first go, keep a build video handy and work slow.
Aim Sports has been turning out affordable parts and accessories for the modern sporting rifle crowd since 2007, and this kit fits that mold nicely. Whether you're finishing a fresh build or replacing worn control parts on a rifle that's seen some rounds, the ARCLPK covers the core hardware without any drama.
It comes with the trigger and hammer assembly, safety switch, bolt and catch, front and rear receiver lock pins, magazine release assembly, trigger guard, and a black polymer pistol grip. In short, it covers the core control parts and small hardware needed to finish a stripped AR-15 lower. You will still need a buffer, buffer tube, spring, and buttstock or brace to complete the full lower group.
Yes, the ARCLPK is built to mil-spec style dimensions and is made to drop into standard AR-15 lower receivers. Most mil-spec lowers on the market are designed for broad compatibility with kits like this one. If you have a specialty or non-standard receiver, it's always worth double-checking your specs before you start.
It works well for first-time builders since it bundles all the small parts into one package so nothing gets left out. The trickiest steps are the springs and detents, particularly the bolt catch roll pin and buffer retainer, so having a vise block and roll pin punches on hand helps a lot. Follow along with a build walkthrough and take your time and you'll be fine.
Absolutely. The kit comes with a functional A2-style polymer grip, but the grip is one of the easiest parts to upgrade later. Plenty of builders start with the included grip and move to an aftermarket ergonomic option whenever they're ready.
