IT'S THE BEST I HAVE EVER USED!.........G.T.G.

Best yet

I hate poorly designed tools that mar the finish on my customers guns. This is not that!!! This is by far the best fitting buffer tube castle nut wrench I've ever used. Thank you Brownells for offering it.

Best by far

I've tried 3 different wrenches in the past. This is the best. Not only does it provide a secure grip on the castle nut with its teeth but it has a shoulder about 1/4" thick. Those two things together ensure that the wrench will stay put while torquing the nut to the required 40 ft/lb.

HIGH QUALITY!

I'm a professional mechanic so I appreciate a quality tool. I've used 2 other brand name castle nut wrenches, they both had the square drive for a torque wrench too far from the mouth of the wrench to be accurate. They also had a loose/sloppy fit and would mar the nut before reaching the 40ft/lbs torque value on the castle nut. The Spikes wrench has the square drive very close to the mouth of the wrench and fits very tight on the castle nut allowing you to torque the nut properly without tearing it up. This tool is what a castle nut wrench is supposed to be, period. Worth every penny...

Only nearly survived one use.

At least my copy of this tool was not hardened. One lug or tooth collapsed almost immediately. The Castle nut was on really hard and had some kind of adhesive so it was really tight but I only used a regular length 3/8 in. ratchet. In my opinion it is designed backwards. It has the circular surface to be guided by the castle nut but it's on the wrong side. This would guide and support the wrench putting a nut ON. No one needs to put the castle nut on that hard but they often are really hard to get off, which is why the guidance and support are needed on the other side of the wrench, then it would support it when taking a Loc-tited or otherwise stuck nut off.
