Question: Does this tool fit the castle nut for commercial buffer tubes?
Document: Came a box big enough to hold two basketballs.Hefty, solidly-built tool. Can double as a blackjack/sap.Will satisfy all your AR wrenching needs (short of a torque gauge, which you can attach).Fit my new-style castle nut just fine, and with gentle handling, didn't scratch my buffer tube at all in the process.Has a bottle opener feature handily labeled &#34;Beer&#34; in case of confusion.
Does everything I expected it to do, the tool does work as advertised. Use some caution when torquing the buffer extension castle nut its easy to deform the slotted grooves your first time around.
Reason for only four stars is the Flat head screw driver is not flat.. Someone could have easily ground it flat before it was painted. For the Price we pay for this tool it is unacceptable.Here's the positives:The finish is nice.Made in the USA.Lifetime warranty.I have only used it to tighten a castle nut on my friends AR buffer. It worked flawlessly at 40 ft pounds.
The tolerance is somewhat loose, but it got the job done. It didn't round the corners. So far, I've used the tool to install flash hider, barrel nut, and castle nut (for buffer tube). I've used the flat tip screw driver to pry down the M4 stock adjustment pin to remove (and later reinstall) the butt stock from the buffer tube. Overall, a great tool.
I'm very pleased with this wrench. It fit properly on the barrel nut, buffer tube nut and flash hider. It's heavy and feels like a quality tool. It has a rubber like coating on it to prevent scratching your rifle.
The only time I have used the tool is to remove and install a buffer tube on my ar-15. The tool didn't really seem to fit on my buffer tube nut like it should. It seemed like the powder coat added a little too much to the tool. I would recommend maybe filing it down a bit if needed.
Excellent lockup to barrel nut..with both the pins and the groove side..Great fit with a 1/2 inch Torque wrench.. Absolutely no slop whatsoever..Only con was the old style buffer tube nut spanner was to large for the old style buffer tube nut..The paint job on the tool is so much better than the Chinese made junk..
I needed it to correctly set a castle nut on my AR-15 after switching from a civi buffer tube to a military one. Worked well -enough-. It would have been nice to have a little more contact in the grooves, I had to be careful not to ding the edges of the nut and make the rifle look junky by doing so. However, it worked well enough to get the job done. It's another one of those standard but no better tapco parts that they're always producing.
I tried to use it to remove a castle nut and it would not work. The tool is coated with so much paint that it does not fit onto the parts of the gun. The green paint also comes off onto the gun.
Who knew it had a bottle opener? All tools have descriptions stamped into tool. Very solid and heavy. It worked to remove/install AR castle nut, but wasn't a solid fit; had to apply pressure to keep the middle tab engaged.
Answer: yes
