Strike Industries AR-15 Carbine Flat Wire Buffer Spring$19.95
Availability: In Stock
The Strike Industries AR-15 carbine aluminum buffer housing is a precision-machined component that lets you dial in your rifle's gas system tune without overspending. Unlike the trigger or barrel that get all the attention, the buffer housing and its weight configuration directly control how your upper and lower receiver cycle together—and getting it right means smoother shooting, better recoil management, and a more reliable platform overall. Strike Industries built this one from 6061-T6 aluminum, a material that's both durable and light enough to keep reciprocating mass exactly where you want it.
What makes this housing genuinely useful is the flexibility it gives you. It ships empty—no weights included—so you can swap in your own tungsten, steel, or aluminum weights to match your specific barrel length, gas port size, and ammunition. That modularity transforms tuning from a guessing game into a straightforward process. The NBR rubber buffer pad absorbs impact and locks in place with the included roll pin, and the housing itself is sized for Mil-Spec standard or carbine length receiver extensions, the most common setup in AR-15 builds.
This is the part of the gas system that most builders overlook until their rifle starts short-stroking or over-gassing. By adjusting reciprocating mass through weight combination, you're essentially fine-tuning how hard the bolt carrier group cycles—heavier buffers slow the cycle rate and reduce recoil impulse; lighter ones speed things up. Strike Industries' modular approach means you're not locked into one configuration; you can experiment and refine until your rifle runs exactly the way you want it to.
| Material | 6061-T6 Aluminum |
| Buffer Weight Diameter Compatibility | 14mm (0.55") |
| Maximum Weight Spacer Height | 14.20mm |
| Receiver Extension Compatibility | Mil-Spec carbine length and standard length |
| Buffer Pad Material | NBR rubber |
| Weights Included | None—housing only |
The Strike Industries housing is compatible with Mil-Spec standard length and carbine length receiver extensions. Verify your current tube diameter and length before purchase if you're replacing an existing housing.
Yes. The housing accepts standard 14mm (0.55") Mil-Spec buffer weights and spacers, up to a maximum height of 14.20mm per spacer. You can reuse weights from another buffer or purchase new ones separately to dial in your preferred configuration.
No. This is the housing only, with no weights or spacers included. You must install weights before using the buffer; do not operate without them installed. You can use weights from an existing buffer or purchase a weight kit separately.
By swapping different weights or combinations of tungsten, steel, and aluminum weights into the housing, you adjust the reciprocating mass of your bolt carrier group. Heavier configurations reduce recoil and slow the cycling rate; lighter ones speed it up. Match your weight selection to your barrel, gas port size, and ammunition to eliminate short-stroking or over-gassing.
