Specifications & Details

| Model | Pineapple Grenade Stripped Lower |
| Finish | Black Hardcoat Anodized |

Built from a 7075-T6 aluminum forging, this lower meets the rigorous mil-spec standard for strength and durability. The weight is a typical 8-9 ounces for a stripped lower, keeping your final build light. Its dimensions are precisely machined to ensure compatibility with the vast ecosystem of AR-15 parts. Look, the real value here is in the branding—you’re paying a small premium over a basic lower for that recognizable Spikes Tactical roll mark and grenade motif, which is a fair trade for many builders. The multi-caliber designation means the lower itself is not caliber-specific; it’s the upper receiver and barrel you pair it with that determines the final chambering. This opens up a world of possibilities from a single registered firearm component.
Who This Lower Is For
This is for the budget-conscious builder who wants a touch of personality without venturing into Gucci-gear pricing. It’s ideal for someone assembling their first AR and wanting a foundation with some character, or for a seasoned enthusiast adding a themed build to their collection. If you appreciate the military heritage aesthetic of the pineapple grenade symbol and want a reliable, no-frills lower that fits out of the box with standard parts kits, this is a strong contender. It’s also a smart choice for those planning multiple uppers in different calibers, as one registered lower can legally host several different complete uppers.
Pros & Cons
Pros: The standout pro is the unique visual appeal at a very accessible price point. The mil-spec compatibility is a huge plus, guaranteeing wide parts availability. The durable hardcoat anodizing means it will look good through years of use. Finally, its multi-caliber nature offers excellent long-term value and build flexibility.
Cons: As a stripped lower, it requires additional investment in a parts kit and tools for assembly. The textured grenade pattern, while cool, might not suit every builder’s taste for a sleek, minimalist look. Compared to a generic, unbranded lower, you are paying a bit more for the logo and design—but that’s the whole point, isn’t it?
Frequently Asked Questions
Q: What parts do I need to complete this stripped lower?
A: You’ll need a Lower Parts Kit (LPK), which includes the trigger, hammer, safety selector, magazine catch, and pivot/takedown pins. You’ll also need a buffer tube kit (buffer tube, spring, buffer, and castle nut) and a stock or pistol brace. A pistol grip and trigger guard are also required, though some LPKs include them.
Q: Is this lower compatible with Palmetto State Armory (PSA) or Aero Precision upper receivers?
A: Yes, absolutely. Since it’s built to mil-spec dimensions, the Spikes Pineapple Grenade lower is designed to be compatible with the vast majority of mil-spec AR-15 upper receivers, including those from major manufacturers like PSA, Aero Precision, BCM, and many others. Proper fit is always recommended, but issues are rare with in-spec components.
Q: Can I build a pistol or a rifle with this lower?
A: You can build either, but the initial configuration is critical. If you intend to build an AR pistol, you must first assemble it with a pistol buffer tube/brace, not a rifle stock. The lower is transferred as an “other firearm” and its final classification depends on how you first configure it. Always consult current ATF regulations.
For a distinctive start to your next AR build that balances cost and character, the Spikes Pineapple Grenade lower is a solid pick. Explore its availability at firearms-missouri.com for Missouri residents and nationwide.
