Kak Buff/Sprn Kt M16 K5 K-Spec 7.3Oz

The Kak Industry K-SPEC buffer and spring kit for M16-pattern rifles gives you a complete recoil-management system in one simple drop-in package. Built around Kak's captured compression buffer design and paired with a flatwire spring, this kit absorbs the bite of recoil while keeping muzzle rise in check—without the complexity or wear-prone parts that plague traditional setups. The K-SPEC system is engineered to eliminate bolt bounce and smooth out the impulse you feel downrange, all with straightforward installation that doesn't demand guesswork or special tools.

This is a no-nonsense upgrade for shooters who want better control and less punishment from their rifle. Whether you're running an AR-15 or other M16-spec platform, the kit handles the job with American-made durability. Everything you need comes in the box: the 7.3 oz K-SPEC buffer, the flatwire spring, and an install tool to get it sorted fast. Drop it into your A5-length buffer tube, and you're done.

Kak designed the K-SPEC to deliver real value without the price tag or maintenance headaches of exotic recoil solutions. It's the kind of upgrade that works quietly in the background, making your rifle shoot flatter and feel friendlier without drawing attention to itself.

Frequently Asked Questions

What rifles does this buffer kit work with?

The K-SPEC buffer and spring kit is designed for rifles using A5-length buffer tubes and M16-pattern receivers. This makes it compatible with many AR-15 and AR-10 platforms, but always verify your buffer tube length before ordering.

What's included in the kit?

The package contains the K-SPEC buffer (7.3 oz), a flatwire spring, and an installation tool. That's everything you need for a complete drop-in swap.

Will this reduce recoil and muzzle rise?

Yes. The captured compression system in the K-SPEC buffer absorbs recoil energy and helps minimize muzzle rise, while the flatwire spring eliminates bolt bounce and smooths out the overall impulse.

Is this a direct replacement, or does my rifle need modifications?

This is a true drop-in replacement for any rifle currently running an A5-length buffer tube. No modifications to your rifle are necessary.
