It works.
Fixing up a friend’s 870 Express; choke tube stuck—penetrating oil for 48 hours, padded vise and mild heat got it out no problem.
Works OK
This choke wrench fits my 870 REM, Mossberg 500, but does not fit my Ruger Red Label factory chokes. Works great but is not universal.
Quality Wrench
I bought this wrench to quickly install and remove choke tubes from my NEF Pardner Pump 12 gauge. This wrench (of course) works with all Carlson's choke tubes but will not work with the modified choke tube that was included with my shotgun. The notches on the choke tube were too narrow for the lugs on the wrench to fit into. I had to resort to the stamped steel Carlson's choke tube wrench to remove my factory original choke tube.
Not "Universal"
This wrench does not fit Mossberg factory 20 ga. choke tubes. The lugs on the wrench are too large to fit in the tubes' wrench notches. However, I was able to file down the lugs until they fit, and now the wrench works with the factory tubes.
Good designs bad build material on handle
Went to use it handle broke off in my hand before it started to move the choke
Very poor design - prone to misalignment
Very disappointing. The centering cylinder is way to small, allowing the tool to rock side to side and making it hard to keep the pins engaged. The standard factory tool works better.
Don't waste your money!
Tool broke first time I used it. Lugs that engage the choke tube are too small and break off easily.
Not Worth The Money
Tool broke first time I used it remove a choke tube. The lugs that fit into the slots in the choke tube are too small and break off easily.
