The DoubleStar AR790 DSC Bolt Rebuild Kit for AR-15 rifles is a practical solution for shooters who need to service or restore a bolt carrier group without replacing the entire assembly. Whether you're maintaining a well-used rifle, bringing a spare bolt back into service, or working through a deep cleaning, this kit gives you the individual components that wear or need periodic replacement. It's the kind of thing serious AR owners keep on hand—a way to extend the life of your platform without unnecessary expense.
AR bolt carrier groups see real wear over time, especially the extractor and gas rings that handle the punishing cycle of firing. The DoubleStar kit addresses the most common wear items: an extractor, spring and bumper pad assembly, a fresh set of gas rings, an O-ring, and the extractor pin. This means you can rebuild a bolt to like-new condition without buying a whole new carrier group. It's a smart move for shooters who run their rifles hard and want to keep spares ready or refresh a rifle that's seen heavy use at the range or in the field.
DoubleStar is known for straightforward, no-nonsense AR parts that work. This rebuild kit follows that pattern—good parts at a fair price, no marketing fluff. If you're comfortable doing your own maintenance (or learning), this kit pays for itself quickly compared to buying a full carrier group replacement.
| Brand | DoubleStar Corp |
| Product Type | Bolt Rebuild Kit |
| Fits | AR-15 Rifles |
| Components Included | 1 Extractor, 1 Extractor Spring with Bumper Pad, 3 Gas Rings, 1 O-Ring, 1 Extractor Pin |
This kit is designed for standard AR-15 bolt carrier groups. It provides the individual wear components—extractor, spring, gas rings, O-ring, and pin—that fit AR-15 platforms.
The kit supplies the components; you'll need basic gunsmithing tools and knowledge of AR bolt assembly to install them. If you're unsure about the process, consult an armorer or detailed assembly guide before starting.
This is a rebuild kit containing individual replacement components—extractor assembly, gas rings, O-ring, and pin. You'll use these to service or rebuild an existing bolt; the kit does not include the carrier or bolt itself.
Extractors and gas rings are wear items. If your rifle is short-stroking, failing to extract, or cycling sluggishly, a rebuild with fresh components from this kit can restore reliable function. Regular shooters often refresh these parts as preventive maintenance.
