Have Questions About this Product?
Wrench is overall a good buy and worth the money. Like many multi-function armorers wrenches it will fit some upper components better than others. Mine is a little loose for installing a castle nut - unless you are paying close attention it can slip. Other parts of the wrench work just fine as it should.
AT3, as always, has the best turnaround on shipping and receiving of your merchandise as well as absolutely THE BEST customer support folks around!
Thanks (again) AT3 Team!
Sure makes AR work easier!! Great service and fast shipping!!
I tried to use the wrench, the wrench does not fit my standard muzzle device. The wrench does fit the barrel nut but appears to be mis-aligned; when any torque is applies it will really try to dis-engage the barrel nut. In all fairness the barrel nut is on extremely tight well past 60 ft./lbs. and could be galled on the aluminum receiver. I am soaking the nut with aero kroil and hoping for the best.
This is my second one! Great product
Not bad. The coating that is put on the tool came with a chip in it and isn’t as smooth and uniform as I would ideally like. That being said the tool seems to function, but if I was going to use it frequently I’d buy something else.
