For those wanting to make their AR15 as compact as possible. Our Mini Milspec System (based on our Original AR15 CQC system) provides you with a compact buffer system while not affecting reliability while still being able to utilize a Milspec BCG. 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
The Mini Milspec Buffer System is compatible with 556/223,300 BLK, 762x39, and similar rifle calibers. The weight of these mini buffers and spring rate of the buffer spring mirror the functionality of a traditional carbine buffer weight/ H Buffer weight. Unlike most short buffer tube setups, ours is designed to function with any compatible Milspec bolt carrier group.

Great product. Easy install.
I put this on my Franklin armory lower with the magpul sl-m. The fit and function are up to par. I’ll bye again.

Best AR accessory I’ve tried in a long time:
A very high quality kit that makes an actual difference in weapon portability / usability that you have to try to believe. This kit is of higher quality than the LWRC version and at a lower price point. Well done KAK!

Mini mil spec buffer tube kit
Works great on my 8.5 300 blk AR pistol I trimmed a SBa4 Brace and it turned out nice . I used the heavier weight version buffer . Buy with confidence , the kit is good quality.

Mini Milspec Buffer Tube Kit
Bought this to shorten up my AR pistol build. The "baby" buffer is adorable and works well in conjunction with the flat wire spring. Force required to pull back the charging handle increased after install, but still manageable. Gun functions perfectly and the kit worked well to remove a couple of inches from my build.

AR15 Mini Milspec Buffer Tube Kit
This thing is dope. I used it with a law folder and a Magpul SL-M stock to get the length of pull when full collapsed back to a standard AR-15. Buffertube and buffer are good quality and the flat round spring doesn't twang like a standard spring. Might have to get a few more of these.

Kak mini buffer
Installed the mini tube and buffer on an 8.5” 300 BLK SBR build. Ran without a failure. Combined with Magpul SL-M stock it makes for an ultra compact setup. I’ll surely buy another if I SBR another lower.

LWRC at home
Purchased for my 14.5 p/w to get the shortest overall storage size along with a UTG S4 stock. Makes it look/feel like a 12.5 AR.

Just what the Doctor Ordered
Perfect CQB addition. Works just like a normal buffer tube system, just shorter. With the shortened scok, really becomes compact. Of note, you really need to use the buffer tool, installing the flat spring and buffer without it was a challenge. My order did not include it, didn't even know it existed until I was done and looking on the website for another kit.
