JP Universal Vise Clamps

JP Universal Vise Clamps are an invaluable asset to any AR-15 builder. Everyone knows the pain of placing your upper in a vice to torque the barrel nut – if you clamp too tight you’ll mar the finish, but if you clamp too loose it will slip and also mar the finish. Traditional vise blocks will protect the finish but will awkwardly torque the upper itself. Your upper receiver was designed to shoot, not be twisted with an insert from below.

Thankfully the JP Universal Vise Clamps solve this issue with a custom solution to fit both large and small-frame receivers. It works differently by gripping the top and bottom of the upper rather than inserting a block into the receiver. This grasps the strongest parts of the upper, the picatinny rail and the front takedown pin, to avoid changing dimensions critical to a smooth bolt. The anodized finish of the clamps provides a smooth surface that will not mar, and the embedded magnets stick to your vise for hassle-free use.

Don’t waste your money on inferior vise blocks or risk the finish of your upper receiver; use the JP Universal Vice Clamps and enjoy peace of mind during your next build.
