Poor tolerances - Strike Industries Grildlok Lite AR-15 M-Lok Handguard Assembly

Another problem with tolerances and a Strike product. Thought I would give them a try against reviews I had heard from other people. Needess to say the product may look great and seem awesome, but it has problems. Barrel nut threads seized up and becoming stuck well before 30 ft-lb of force (yes, grease was applied before starting the installation).. Strike's customer service is also no help. Needless to say, I won't purchase this product or another product again from Strike Industries.
