"I think this tool is great, but this one itself was terrible. I was changing my commercial stock for a mil-spec, to throw on a magpul A-frame. Had it on right and stripped the castle nut. I was also throwing on a battle comp 2.0 compensator and I damaged the stock bird cage flash hider. Look for a better one, this one's molding was off by a 1/16th of an inch. Will damage your parts to mount and remove them."

"I was worried about this item because of the low reviews, but it worked great for installing my barrel."

"I haven't had any real issues with this wrench. It held up to about 55 ft/lbs on my free float barrel nut. I was worried about the pins breaking, but it held up."

"I needed this mount to help me put a YHM handguard on my M4. The barrel nut was very, very tight from the factory, but this tool \"MANNED UP\" and got the job done, with no damage to the tool or firearm. I also set the barrel nut with it and it worked perfectly. I flipped it around and tightened the jam nut. Using this mount as a tool helped me cut my build time down measurably."

"This wrench worked, but if you have to use the side opposite the 3 post, you may run into trouble. It will not grip the barrel nut and slips off when pressure is applied, due to the coating thickness on the wrench. I do have to say that CTD's customers service is top notch. I ordered this on Wed. at 3:45 CST and received it on Fri. afternoon."

"I got this in 3 days. Thanks, CTD. I changed out the upper on my AR-15 and had no problems. It held up great."

"I used it to remove the buffer tube on my AR-10, and it held up great. I really like the heavy duty feel. Only reason why I didn't give five bullets is because I only used one of its many functions, and I can't comment on the others at this time. Also, I received it uber fast. Thanks, CTD. I had a malfunction with the rifle on Sunday, ordered Monday, and received it Wednesday. Uber fast."

"Used the tool for removing the castle nut and it worked great. I have not had a chance to use all functions yet. Tool seems well made."

"Complete junk. Soft metal shredded while trying to loosen the barrel nut. Three prongs are not enough if they just bend and shear."

"Gave it a chance but immediately regret it. As others stated, its made out of soft metal and does nothing but bend and shred the teeth. Couldn't use it to remove my castle nut so had to have my CATM guys get it for me. Spend a little more to get better quality."

"I bought this tool while disregarding the negative reviews. To my surprise, it wasn't grey like in the photo, but black. My barrel nut was pretty stubborn, but a 1/2\" breaker bar broke it loose. I only gave it 4 bullets because I haven't used the castle nut part yet."

"Purchased one of these for my shop. As a gunsmith, it pays to keep at least one of everything - and usually a spare for high demand tools. For it's part, CTD did everything right. Good price, quick shipping. That, sadly, was where the niceties ended. First off, the 3-pt castle nut wrench fits a little loosely on every AR nut I've tried so far; this section's teeth are also overly tapered and slightly under sized. Combine these details and it translates into a two-handed job just to HOLD the wrench on a castle nut... forget about applying any torque yourself. Once I got a friend/minion to apply force on the wrench I learned about its other fatal flaw. We actually started off using the S-curved wrench on a castle nut first, but that part of the wrench actually flexed and warped before the nut popped loose. Not just a little bit, either. With the rest of the lower locked firmly in a gun vise, the distant end of the wrench traversed a good 7-8\" while the S-head remained firmly in place. (That's what prompted me to use the other wrench and discover its limitations.) I do not know what this thing is made of, but I watched the tool's black finish turn gray, then silver as the metal flexed into a new shape. Overall, I am disappointed. This tool is a fine example of poor execution of a great idea."

"Made of soft metal and broke trying to remove the castle nut."

"This is your basic AR15 all-in-one armorers tool. With it, and a good set of upper & lower vise clamps, you can pretty much assemble & disassemble most of the major (large) component assemblies of your black rifle like removing the barrel, the flashider/comp, and working with the grip assemblies/rails. It is not going to be of much help with the small stuff though: assembling your lower parts kit, or working on a BCG.It is a heavy duty piece of powder coated steel, that if all else fails could be used to beat your uncooperative aluminum based rifle into so much slag for the recycling bin."
