Description
The buffer is one of those parts nobody thinks about until their rifle starts short-stroking or beating them up on the shoulder. Strike Industries built this mil-spec buffer housing for the folks who want to take that part into their own hands. It ships as the housing only, so you supply the weights and spacers and tune the reciprocating mass to match your gas system, ammo, and setup. The red hardcoat anodized finish is a nice bonus that shows off through a clear or skeletonized stock.
What Sets the Strike Industries Buffer Housing Apart
Instead of a sealed factory buffer with a fixed weight, this one opens up the whole system to you. It accepts standard 14mm diameter mil-spec buffer weights and spacers, so you can stack tungsten, steel, and aluminum in whatever combination gets your rifle running clean. Running an adjustable gas block or a can? This is how you fine-tune the impulse rather than guessing at a carbine, H, or H2 buffer off the shelf. An NBR rubber buffer pad on the back end soaks up the impact against the receiver extension and is held in place by an included roll pin.
Fit and Construction of the Red Anodized Housing
Everything is machined from 6061-T6 aluminum, so it stays light and holds up to the constant hammering a buffer takes. It's cut to mil-spec dimensions and drops into both mil-spec standard and carbine length receiver extensions with no fitting or modification. If your buffer tube takes a normal carbine buffer, this housing will slide right in.
Getting the Most Out of It
Keep in mind this is the empty housing, not a complete loaded buffer. That's the whole point, it lets you build the exact weight you want, but you'll want weights and spacers on hand before you assemble it. Pair it with a quality flat wire or standard carbine spring and you've got a fully custom recoil setup for a fraction of the fuss of swapping complete buffers over and over.

Frequently Asked Questions
Does the Strike Industries buffer housing come with weights?
No, it ships as the housing only with no weights or spacers installed. That's intentional, since it lets you supply your own combination of tungsten, steel, and aluminum weights to tune the buffer to your rifle. You can reuse the weights from your current buffer or buy separate weights to build the exact mass you want.
Will this fit my AR-15 buffer tube?
It's machined to mil-spec dimensions and fits both mil-spec standard and carbine length receiver extensions with no modification. If your rifle uses a standard carbine buffer now, this housing will drop right in. It works with 14mm diameter mil-spec buffer weights and spacers.
What is the red buffer housing made of?
It's machined from 6061-T6 aluminum, which keeps it light while standing up to the repeated impact a buffer sees. The red hardcoat anodized finish adds wear and corrosion resistance on top of the color. An NBR rubber pad on the rear absorbs the impact against the buffer tube.
Why would I use an adjustable buffer housing instead of a standard buffer?
A fixed buffer gives you one weight, while this housing lets you stack different weights and spacers to fine-tune your reciprocating mass. That's especially useful if you're running a suppressor, an adjustable gas block, or ammo that changes your rifle's impulse. It saves you from buying multiple complete buffers to chase the right feel.
