after trying 2 of those and both deforming like hot pretzel dough at about half torque spec.......problem solved with a Magpul wrench......pricey yes but "buy once cry once"

What he said. There is a TON of junk AR parts and tools on fleabay.

Buy from a reputable gun website and look at the ratings before buying.

Remember you get what you pay for.

Agreed. Pricey, but well worth it. :D
 
Late Post

I found decent wrench made by Wheeler. Armorer tool. Came with torque wrench. Works well on castle nut and has many uses.
