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 as intended.

    Only have used it once so far. But it works like its supposed to. Replaces a few other tools that will probably never see the light of day again.

    Must have tool

    Posted by Dave on 31st Jan 2019

    For any serious AR builder this is a must have tool. Perfect barrel alignment, takes away torque from the upper receiver when used for the barrel nut. Versatile to use when changing muzzle brake or any other barrel related projects.

    Excellent tool

    Posted by Brandon on 20th Jan 2019

    I got this to put together a new 6.5 Grendel upper build, and so far it seems to be a great product. I've never actually held the one Geissele makes, but this one seems to be pretty solid. Literally. It's a solid steel shaft, with a good engagement on the spline end. I haven't tested it against high torque applications, but for the basic 30 ft-lbs torquing of the barrel nut it worked great. Definitely a good bargain, being (at the time of purchase) ~$30 cheaper than the big brand, and a little more versatile than the Magpul BEV block. If I had to do it all over again I would make the same choice.

    KZ Barrel Spline Socket for AR15

    Posted by Ryan on 20th Jan 2019

    I ordered one of these for use with building upper receivers. I have used it several times recently to remove and/or install barrel nuts and muzzle devices. It works great and costs a fraction of what the competing products do.
