Description

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.

Features:

  • For all AR15/M16/M4/AR10/SR25 Type Rifles & Pistols
  • Securely holds an upper receiver assembly for maintenance and assembly work
  • Removal & installation of barrels, flash hiders, gas blocks and hand guards is made much easier and simpler

    Works perfect good fit

    Works perfect for putting the barrel on your upper. You don't have to worry about cracking the upper all the torque goes into the barrel extension with this tool. The quality seems good to me. I am sure this tool will last a lifetime. I stuck it into a Daniel Defense barrel extension and a Rainier Arms Ultramatch barrel extension to test its fit. The fit seemed just right to me. I am happy with my purchase.

    A necessity for AR assemblers! Build it or re-barrel it yourself!

    Posted by Kevin D. on 9th May 2018

    I've been into AR's for 4 years now and its interesting that it took this long to "notice" such an obviously necessary tool. Is this a totally new concept or just something I was unaware of? I know of one other manufacturer of what appears to be essentially the same product. The Kley Zion item is much lower in price and I have been pleased with every other KZ item I have purchased. For assembling an AR upper, this tool is far superior than a plastic block you insert into the magazine well. If precision is key, this allows for more accurate torque readings when tightening the barrel nut.

    Used it to build my first two AR15s, worked great.

    Posted by Keith on 9th May 2018

    I used my reaction rod on my first two AR build and it worked great to screw on the barrel nut, the flat end clamped tightly in the vise and both barrels were tightened to near 50 foot pounds to get the gas tune to align and the tool preformed flawlessly.

    good, but needs more thought.

    Posted by Fletch on 9th May 2018

    Flats for the vice are not indexed to have the upper lever or front sight vertical. You need to fix that.
