Description
MPN: 522-1702-108 / 522-1702-109
Features:
- Designed for AR-10 Platforms: Engineered specifically for large-frame AR systems where increased mass and recoil require greater control than standard buffers
- K-SPEC Enhanced Buffer Technology: Features a two-piece, reciprocating buffer body with an internal captured spring that absorbs energy and smooths the recoil impulse
- Reduced Felt Recoil: The internal spring system softens rearward impact and moderates the return stroke, helping the rifle stay flatter and easier to control
- Minimizes Bolt Bounce: Controlled buffer movement helps reduce bolt bounce, improving reliability during rapid fire and sustained strings
- Multiple Weight Options Available: Offered in different weight configurations so shooters can tune their rifle for gas system length, ammo, and suppressed or unsuppressed use
- Drop-In Installation: Fits standard AR-15 carbine-length receiver extensions with no permanent modifications required
- Made in the USA: Manufactured by KAK Industry with a focus on durability, consistency, and real-world performance

Details:
Large-frame ARs bring more mass and energy into the recoil cycle than an AR-15, and a basic buffer doesn’t always do enough to manage it. The KAK K-SPEC Enhanced AR-10 Buffer is designed specifically to smooth out that heavier impulse, helping .308 and other big-frame rifles shoot flatter and feel more predictable without compromising reliability.
Guided Movement Instead of Loose Mass
The difference is inside the buffer. Rather than relying on short, free-floating weights that slam back and forth, the K-SPEC design uses extended internal weights separated by polyurethane spacers. This creates a guided, controlled movement through the entire stroke. The effect is less internal noise, reduced bolt bounce, and a recoil impulse that feels more linear instead of abrupt. On the shoulder, the rifle feels calmer and easier to manage, especially during faster follow-up shots.
Designed for AR-10 Carbine Systems
This buffer is intended for AR-10 / SR-25–pattern rifles running a carbine-length receiver extension. Installation is exactly the same as a standard buffer swap—no special tools, no guesswork. When paired with the included flatwire spring, the recoil system settles into a smoother, more composed rhythm right away.
A Noticeable Upgrade Without Added Complexity
Once installed, most shooters notice a quieter cycle, less harsh rearward impact, and a rifle that feels less violent overall while still running reliably. It’s not a dramatic overhaul—it’s a refinement that brings control back to where it should be. If your large-frame AR feels sharp, noisy, or unsettled, the KAK K-SPEC Enhanced AR-10 Buffer is a straightforward upgrade that makes a real difference without complicating your build.
