P&L DEVELOPMENT - AR-15 Barrel Extension Wrench

I've used these extensions extensively in a professional capacity and have found no major problems with them. They're perfect for the gunsmith producing around 20 barrels a year. They can be easily damaged If used improperly however and overall service life is limited due to the overall hardness of the steel. The hardness does provide for a measure of safety in that it prevents the corners of the extensions from being damaged and keeps the risk of catastrophic failure of the tool to an absolute minimum.

Had this model and used it for two years. Worked great but it finally broke. Have ordered and broken six in the last three months. Clearly the material is cheaper or the hardening process has been skimped. Will no longer be using this product. Very unfortunate.
