Got the job done
by Nathan -
It got my job done, but in my opinion the wrench is a bit too too thin and difficult to hold onto (even with gloves.) If you plan on doing any castle nut or buffer tube work, I might recommend spending 4-5x the cost and getting a high quality armorer's wrench instead.
Wrench too small, can't fit over Magpul UBR Gen 2 Nut
by Rez -
When trying to use it on my Magpul UBR Gen 2 nut, the wrench is way too big and is too loose on the nut. The wrench is also showing signs of wear after trying to remove the nut in the first day.
I love it but...
by Andres -
Works perfect as a dedicated tool, but i cant figure out what the middle oval hole is for? i would prefer a 3/8" square to attach a torque wrench, 1/2" doesnt work in it either.
Cheap and works
by David -
needed to remove buffer tube but didn't want to break the bank worked prefectly
Virtually impossible to damage your tube threads.
by DUSTYN -
This tool is awesome, and the spanner is precision enough so it cannot touch the buffer tube threads. Best one I have in my box for this job!!
Does what it needs to do
by Will -
Bought this for my first full lower build and it does what it needs to do! Simple and effective!
NOT FOR USE WITH TORQUE WRENCH
by Alexander -
The description lists this tool as accepting a 1/2" torque wrench, but as others have pointed out, the slot in the wrench is much too big to properly fit 1/2" drive. Other tools with this design label that slot as an A1/A2 flash hider wrench, which is what it actually is. This wrench is only to tighten by itself, not in conjunction with a torque wrench. Probably would be okay for the flash hider, but since it's impossible to measure torque for the castle nut, it's not useful for that.
From PA: We're very sorry for the confusion and we'll get our page updated.
Good product
by Isidro -
Works great, functions as it should. Couldn't beat the price
Gets the job done ... barely.
by Neth -
Gets the job done but only by hand, which is difficult considering its small size and thinness. Does not properly fit a 1/2" torque wrench. The hole is way too big at .65" from flat to flat and strips once you apply a little force. This tool is the bare minimum to get the job done. Get a higher quality one if you plan on more than one build.
Works!
by Ben -
I didn't need a full armors wrench just something for the castle nut (cheap enough to justify over using a punch to set the castle nut). While I didn't use the torque wrench cutout, I will now that my build is confirmed working. Wrench worked great!
