THIS BUFFER TUBE SYSTEM IS PATENT PENDING
Simple yet perfect. I used the smaller spacer and it was exactly what I hoped for.
Ordered these for my old SIG brace on the KAK buffer tube. They fit snug and function perfect, with the option to adjust length as needed. 10 out of 10, would buy again... Like everything else I've ordered from KAK.
small spacer with my sb tactical arm brace and the KAK buffer gives me the same length as a full extended stock.
Purchased this kit to lengthen the pull on LR308 pistol build with the KAK buffer tube. Works great and got the length of pull right where I needed it!!!
Excellent quality, great service
works like a charm...
Great Add-On to Go With KAK Buffer Tube
Got this kit to lengthen the pull on an AR pistol build with the KAK buffer tube along with the Thordsen Customs Enhanced AR Pistol Builder's Kit (buffer tube cover, adapter kit, CAA saddle, etc...). Works great and got the length of pull right where I wanted it.
best setup yet
used this ring kit with the KAK Pistol Tube and Sig Brace to properly stabilize my pistol by adjusting for my length of pull; trigger finger to inside of elbow. design, fit and function are spot on.
Great Quality Product, Should be standard with the pistol tubes!
These spacers are perfect for the KAK pistol buffer and SB-15 brace. With the tube, spacers and brace installed, the length of pull matches my Ruger 10/22 Takedown, which is perfection. It's great to have the option to shorten this at will.
