Description
K-SPEC Enhanced PCC Buffer for reduced felt recoil!
The K-SPEC Buffer was developed with specific goals in mind- Reducing felt recoil and providing faster follow up shots for Pistol Caliber Carbines.
Why Use the KAK 9.5 oz SPEC Enhanced Buffer?
1) This system will help to tame the recoil in your Pistol Caliber Carbines (PCCs). In blowback-operated guns (like 9mm ARs), the bolt relies only on spring and buffer mass to slow it down. A standard 3 oz carbine buffer is too light, which can cause violent cycling, more felt recoil, and increased wear.
A 9.5 oz buffer adds enough mass to slow the bolt, making the recoil impulse softer and more controllable.
2) With heavy pistol-caliber bolts, timing is critical. The 9.5 oz buffer helps keep the cycling speed consistent, reducing misfeeds and out-of-battery risks.
Especially useful with suppressed 9mm ARs or subgun setups.
3) Heavy buffers help the bolt lock up more consistently instead of bouncing forward/back on impact. This is especially important in competition PCCs where reliable lockup is mandatory.
This system is for use with Pistol Caliber AR15 firearms utilizing a one-piece BCG and Compatible with Carbine buffer tubes and our Flatwire buffer spring.
The K-SPEC Buffer features an innovative recoil reduction system that absorbs and disperses felt recoil. Minimizing muzzle flip and kickback allowing you to fire faster and more accurately by being able to stay on target more effectively.
The K-SPEC Buffer features a two-piece reciprocating buffer body and a custom captured compression spring mechanism internally, which works in conjunction with our flatwire buffer spring. The majority of the felt recoil is transferred into the buffer spring, and then dispersed into the K-SPEC buffer internals which absorb recoil and distributes recoil more evenly and linearly instead of abruptly as you experience with traditional buffer systems.
