Odin Works Adjustable Buffer for AR-10/LR-308 Carbine

The Odin Works adjustable buffer for AR-10/LR-308 carbine gives you real control over your rifle's cycling and felt recoil without swapping the whole tube. Instead of guessing which off-the-shelf buffer works best with your specific ammo, suppressor setup, or bolt carrier group, this one lets you dial in the weight that matches your build. It comes with three interchangeable weights—aluminum, steel, and tungsten—so you can find the sweet spot where your gun runs reliably and shoots as smoothly as you want.

Tuning an AR-10 platform rifle often means chasing the right buffer weight. Too light and you get unreliable feeding or short recoil travel; too heavy and you're beating up the receiver extension with unnecessary force. The Odin Works design eliminates that trial-and-error by giving you the weights to experiment right out of the box. Each weight moves the balance point differently, so whether you're running suppressed or unsuppressed, shooting heavy or light ammunition, or working with a different BCG than the last guy, you can adapt without buying multiple buffers.

The buffer body itself is 303 stainless steel, built for the carbine length tube standard on most AR-10 platform rifles. Installation is straightforward—drop it into your existing buffer tube and swap weights as needed to dial in your preferred function. This is the kind of no-nonsense part that appeals to serious builders and shooters who understand that one size doesn't fit all.

Frequently Asked Questions

Will this buffer work with my AR-10 or LR-308 rifle?

Yes, if your rifle uses a carbine length buffer tube. This buffer is designed specifically for the AR-10/LR-308 platform in carbine configuration.

What's included in the box?

The buffer comes with the stainless steel body and three interchangeable weights: one aluminum, one steel, and one tungsten. You swap these in and out to adjust the total weight and tuning.

How do I know which weight to use?

Start with one weight and observe how your rifle cycles. If you're getting short recoil travel or feeding issues, try a heavier weight. If recoil feels too harsh or the bolt is over-traveling, try a lighter one. The three weights give you flexibility to dial it in for your specific ammunition and configuration.

Do I need any special tools to change the weights?

The weights are designed to be swapped easily, but we recommend checking the manufacturer's instructions for your specific model to understand the best process for your setup.
