This is a proprietary item designed to work with our mini buffer and our flat wire spring only

We are listing these for people who want to use these for folding receiver extensions to achieve better length of pulls with AK47, Galil, and similar

We take no responsibility for any issues that may occur for mixing and matching buffers or springs that are not designed for this proprietary KAK mini buffer tube, only KAK Industry produced flat wire buffer spring and mini buffer are designed to work with this item

The M4 stock is taken down from just over 6.5" to 5", Mini Buffer Tube is only 5.25" in length from end of the receiver when installed. The Mini Milspec M4 Stock can collapse completely flush in the last adjustment hole on the buffer tube making the front of the stock flush with the castle nut.

Mini Milspec Buffer Tube with Mini M4 Stock Installed, collapsed configuration- 5 5/8” from back of receiver

Normal Milspec M4 stock with 6 position buffer tube- 7 1/8”

Magpul SL-M will collapse flush with castle nut in 2nd adjustment slot, .5" longer than KAK Mini M4 Stock

    Picked up this mini buffer tube, flat wire spring and both the buffers (for weight options). All in all this is an incredibly small package. VERY cool. And the best part, this is cheaper than LWRCI. After seeing KAKs mini M4 offering, I have zero clue as to why anyone would get the double the price LWRCI kit.
