Smith & Wesson M&P 22X & Compact Factory Barrel Nut Wrench

I have been struggling for weeks to remove my barrel nut without damaging it. Tried heat and destroyed two home made wrenches. When I received this wrench I had the nut off within two minutes. During my struggles Smith and Wesson and Gem-tech were no help, the adapter I ordered from Gem-tech did not fit, the adapter from EWK threaded right on. The workmanship and part quality are very high and the customer service and delivery are the best I have ever encountered. I can't say enough about Eric and his company.
