Anyone who's built or torn down an AR lower knows the pain of a tiny detent spring launching itself into the carpet, never to be seen again. The Armaspec Spare Parts Kit is built to save that headache. It rounds up the small, easy-to-lose parts that live inside your lower receiver and packages them together so you're never stuck mid-project hunting for a replacement.
This kit covers both AR-15 and AR-10 platforms, meaning it fits 5.56/.223 and 7.62/.308 lowers alike. Everything inside is machined from stainless steel, which gives you better corrosion resistance and a smoother feel compared to a lot of the standard mil-spec parts that ship in budget lowers. That matters for the pieces doing the real work here, like your detents and retainer, since they see constant contact and wear over time.
You get a full spread of the usual suspects: 3 takedown/pivot pin detents and their springs, a safety selector detent and spring, a buffer retainer and spring, a bolt catch detent and spring, and a magazine catch spring. Having three of the pivot detents is a nice touch, since those are the ones most likely to go flying and get lost during install. It's a spare parts kit at heart, not a complete lower parts kit, so keep that in mind if you're building a lower from scratch and need triggers or a grip.
Think of it as cheap insurance for your armorer's box. Toss it in your range bag or leave it on the workbench and you'll have the odds-and-ends parts ready whenever a spring wears out or a detent vanishes. It's made in the USA and backed by Armaspec's lifetime warranty, so it's an easy thing to have around whether you're maintaining one rifle or a whole safe full of them.
Yes, it's designed to work with both platforms, covering 5.56/.223 and 7.62/.308 lower receivers. The detents and springs are the common small parts shared across most standard AR lowers. It fits the vast majority of mil-spec compatible receivers on the market.
No, this is a spare parts kit, not a full lower parts kit. It covers the small, frequently lost detents, springs, and retainers rather than a trigger group, grip, or safety selector body. If you're doing a full build, you'll want a complete LPK and can keep this on hand as backup for the pieces that tend to disappear.
The detents and the buffer retainer are machined from stainless steel, which gives you better corrosion resistance and smoother operation than typical mil-spec parts. The springs round out the package so you have a matched set ready to install. It's a nice step up in materials for parts that see constant wear.
These tiny parts are notorious for launching across the room during assembly or wearing out over time. Having a spare set on your bench or in your range bag means a lost detent won't sideline your rifle. It's simple insurance for anyone who works on their own ARs.
