Frequently Asked Questions
Will this buttstock kit work with my existing AR-15 lower receiver?
Yes. The KAK M16 A2 Rifle Buttstock Kit is designed to fit any standard AR-15 lower receiver that accepts a mil-spec rifle-length buffer tube. The included A2 extension tube threads directly into the lower receiver's buffer tube socket, making it compatible with the vast majority of AR-15 lowers on the market. No special modifications are required for installation.
Can I use this rifle-length buffer system with a carbine-length upper receiver?
Absolutely. A rifle-length buffer system is determined by the lower receiver setup, not the upper. You can pair this A2 fixed-stock kit with any standard AR-15 upper receiver — carbine, mid-length, or rifle-length gas systems — as long as your lower receiver accommodates a rifle-length buffer tube. The longer buffer and heavier spring simply manage bolt carrier group recoil within the extended tube.
What is stored in the A2 buttstock's storage compartment?
The built-in storage compartment inside the A2 polymer buttstock is sized to hold small cleaning accessories such as a cleaning rod, bore brush, patches, and a small bottle of lubricant. It's a classic feature of the original M16 A2 design, giving shooters a convenient on-board storage solution without adding bulk or weight to the rifle.
