KAK Industry K-SPEC AR-15 Buffer and Spring Kit, 4.7 oz

The KAK Industry K-SPEC AR-15 Buffer and Spring Kit, 4.7 oz (brand part no. 522-0704-107) pairs a 4.7-ounce K-SPEC buffer with a matched spring, engineered by KAK Industry to cut felt recoil and speed up your follow-up shots. The design borrows from recoil-management systems already common on pistol platforms, moving away from a single-piece recoil rod toward a dual recoil rod spring assembly with a compression guide rod. That extra stage of compression smooths out the buffer’s motion instead of letting it slam through the full cycle in one sharp movement.

Key Specifications

• Buffer weight is 4.7 ounces.
• Uses a dual recoil rod spring assembly with a compression guide rod.
• Designed to reduce felt recoil compared to a standard single-piece buffer.
• Built to speed up follow-up shot recovery by smoothing the cycling motion.
• Sold as a matched buffer and spring set.

Frequently Asked Questions

What does the dual recoil rod design do? It adds a second stage of spring compression, similar to systems used on pistol operating systems, which smooths the buffer’s cycling motion instead of a single sharp impulse.

Is the spring included? Yes, this is a matched buffer and spring kit, not a buffer alone.
