AR-15 COMBO Upper, Lower, Trigger Test Receiver Vise Blocks & Cleaning Link Armorers Gunsmith Tool
Fantastic combo 4 pack! You get one upper receiver block set for assembling a barrel on your upper, one lower receiver block to assemble your trigger, buffer tube , trigger guard and butt stock, one trigger testing block and one cleaning link to help with in field maintenance chores! The lower fixture will allow you to work on your lower with the upper receiver installed or removed, while clamped firmly in your shop vise. You can install this through the top or bottom of your receiver to allow easy access to trigger guard, pistol grip or buffer tube, or to work on your trigger, safety and takedown pins. The upper fixture will allow you to work on your A3 flat top upper with the bolt and charging handle installed or removed, while clamped firmly in your shop vise. You can clamp it vertically for cleaning or horizontally for barrel work with the use of the flat top rail cap, to protect your weaver rail from scratches and abrasion. This fixture comes with 2 Lexan poly carbonate anti torque plates to positively locate your upper securely in the fixture during gunsmith work. The Anti-Torque plates will allow you to securely work on your receiver on top of your workbench without the worry of scuffing or scratching your receiver and give you a firm hold to steady the receiver on any flat surface. The upper rail block is extra thick and is the full length of your receiver providing great full support when held in your vise. Your vise may have jaws that are smaller in width than your receiver, this block set will allow the pressure from the vise to be evenly distributed to the full width or your receiver, increasing the holding power and decreasing the risk of deforming your receiver by applying too much force on too small of an area. Simply insert the cleaning link between your upper and lower receiver and secure it with your rear takedown pin and the provided clevis pin. Cleaning your barrel and receiver will be much easier without having to wrestle with a loose receiver.
