KZ Barrel Spline Socket Rod For AR15/M4 Upper Receivers
A great tool that securely holds an upper receiver assembly for maintenance and assembly work. The removal and installation of barrels, flash hiders, gas blocks and hand guards is made much easier and simpler. Designed to be gripped in a bench vise so that the rod is either horizontal or vertical. The upper receiver is then slid onto the rod and the rod’s integral splines enter the barrel extension and secure the barrel extension from turning.
This allows all the torque from barrel nut wrenches to go directly into the barrel extension. The receiver vise blocks transmit the turning force into the aluminum receiver, a good part of which passes through the small, easily distorted receiver index pin. With the Barrel Spline Socket Rod, marring of an upper receiver’s finish by gripping and twisting inside vise blocks is eliminated and so is the need to remove sights and mounts from the receiver’s M1913 rail.

Good piece of equipment. Did exactly what it was intended to do. If you are building an AR from scratch, be it AR15 or AR10/308, you should use this to mate the barrel to the receiver. You need to anchor at the strongest point and the steel lock at the chamber mouth is just that.
Works awesome! Have built several uppers since getting it.
The aluminum socket rod worked well for both my 5.56 and 7.62x 39 (KS47) AR15 style rifles. Made it much easier and safer to replace muzzle devices.
Worked perfect for a great price
Worked great. Great price.
Works as good as the expensive ones!
Very well thought out tool. Resemble priced too.
Did my first AR build and found this tool worked exactly as advertised. It is well made, it holds your upper receiver and barrel securely while you torque down the barrel bolt. You have to do that 3-4 times to season the threads and to get the gas tube indexed properly. You need this tool to hold everything securely. Makes the job a breeze.
Great product a must have tool for vertical AR Barrel install not like horizontal upper vise block
So happy with this tool I bought two of them. Excellent product at an even better price! Highly recommended!
