Strike Industries
The Strike Industries AR Mil-Spec Buffer Housing is a precision aluminum component built to help you dial in your AR-15's gas system. Whether you're running a piston gun, suppressed setup, or just want tighter control over your rifle's cycling, a properly weighted buffer makes a real difference—and this blue anodized housing gives you the platform to tune it. Machined from 6061-T6 aluminum, it's built to spec and plays nicely with standard mil-spec receiver extensions and carbine-length tubes.
What sets this housing apart is its modularity. It ships empty—no weights included—so you choose your own weight recipe. That's a genuine advantage: you're not stuck with whatever the factory packed in, and you can experiment with tungsten, steel, or aluminum weights (or spacers) to match your exact setup. Want a softer recoil impulse? Lighter cycling? A bit more bolt velocity for reliability? Mix and match weights to get there. The NBR rubber buffer pad absorbs impact and stays put via a roll pin, and the anodized finish is durable and good-looking.
This is old-school tuning—the kind that precision shooters and builders have relied on for years. It's not flashy, but it works. If you're the type who sweats the details of gas system balance, this housing is worth the investment. Just remember: you'll need to source weights separately and install them before use—running it bare will damage the receiver.
| Brand | Strike Industries |
| Material | 6061-T6 Aluminum |
| Finish | Blue Anodized |
| Compatible Receiver Extensions | Mil-Spec Standard and Carbine-Length |
| Weight Diameter | 14mm (0.55") |
| Maximum Weight Stack Height | 14.20mm |
| Buffer Pad Material | NBR Rubber |
| Included Weights | None |
| Included Hardware | Roll Pin |
Yes, if your rifle uses a mil-spec standard or carbine-length receiver extension (buffer tube). This housing is designed to drop into either configuration. If you're unsure what you have, measure your buffer tube diameter—mil-spec tubes are 1.148" OD.
The housing comes empty, so you'll source weights separately. It accepts standard 14mm (0.55") diameter mil-spec weights—tungsten, steel, or aluminum—stacked to a maximum of 14.20mm total. The specific combination depends on your gas system, ammunition, and desired recoil impulse. Start with what other builders recommend for your barrel length and gas port size, then adjust from there.
No. Running the housing without weights installed will damage your receiver. You must install at least some weight before cycling the bolt. If you're not ready to source weights, consider a complete factory buffer assembly instead.
This housing gives you the freedom to tune your gas system independently. If you already have weights you like, or want to experiment with different weights for different loads or barrel lengths, this platform lets you do that without buying whole new assemblies each time.
