AR15 Armorer's Barrel Nut Castle Nut Wrench for M4 M16 Multi-Fuction Tool

great item

Item broke on first use and it has been a hassle to get a refund. Company is trying to say it is user fault instead of admitting the product quality is poor.

Spanner tip broke off during the first use.

I checked, as per OhHunt's recommendation. They indicate that the fit is too sloppy to work without damaging the barrel nut. They do suggest an alternate wrench but have no idea where to find it.
The upper vise block won't fit my Aero upper either. A complete bust.

All tools and parts worked perfectly.

AR-15 Armorer's Wrench for Barrel Nut Castle Nut M4 M16 Multi-Fuction Tool

Had a cheapie wrench before that wouldn't stay on the castle nut. Got this one at a good price - love it. Nice grip on the handle and a lot better balance for torqueing.

I bought the upper receiver vice block and when I received it I opened the bag it was in and took it out to look at it. When I separated the two halfs something fell out and I found it on the floor. When I looked at the block halfs I noticed that one side had two holes and the other side had one locating pin on closer inspection I saw a divot that matched the part that fell out. I glued the part back to where it belonged where it stayed until I used it to hold the upper receiver while I torqued the barrel nut holding the barrel to the receiver. It worked like it was supposed to even though a locating pin broke off in shipping which is not a big concern for me because I will drill a hole and install a new pin solving the issue. I am happy to have this new tool that works great and was affordable because the local stores wanted four times the price that I paid for it for the same thing.

Accessories where good quality. Everything worked well on the upgrade. Looks very good on my rifle. Shipping was a little slow.
