Good enough to serve its purpose
It was affordable and did the job the points that rest in the castle but bent a little but it’s still usable

GO > AR
A terrific tool. I would buy another one and then give it as a gift to someone else.

Could be worse, could be better.
A little "flimbsy" for "real" work. If you need a quick fix without dropping a lot more money on an armorers tool, this will get the job done.

Out of Tolerance
Both the castle nut and the buffer tube wrench were a tad to small. Do yourself a favor and spend the extra money for a good wrench.

The castle nut wrench wor
The castle nut wrench worked fine but the wrench to loosen the buffer tube on my pre-ban AR did not.

Answer:
Yes.
Will it work to change the buffer tube on Tippman M4 22 ?
Answer:
Yes it will.
Can I use this to change a muzzle break ?

It should work for a Standard A2 bird cage but compatibility with other muzzle breaks is questionable.
I need a low profile (thin) wrench to access the castle nut on a new build. I have the Real Avid Armorer's kit, but the wrench profile is too thick to access the castle nut. will this work?

This one is about as small as it gets. So possibly.
