    How would you get a small cylinder (5.1 in length, -5.4in girth) unstuck from a filled KAK AR15 MIL-SPEC CARBINE BUFFER TUBE with butter and microwaved mashed banana? Worked great for finishing up a build, as Always KAK makes great parts at an affordable price.

    Very good all around receiver extension

    Never had any fitment issues with a KAK product. Including this one. I used a jig to keep it in the correct clocking location when torquing the castle nut. Properly staked afterwards.

    Mil-Spec buffer tube. Everything fit correctly, properly anodized and doesn't look like a blem so it gets 5 stars from me.

    Exactly what it's supposed to be.

    Good, strong, and does exactly what it is supposed to do. The finish is good, and the threads were cut perfectly. I had no issues whatsoever fitting this to my lower. Unless you're looking for some high tech, high speed low drag, infinite adjustment titanium buffer tube, this is what you want. Righteously priced as well.
