Didn’t fit
The tool would not fit in my 12gauge Mossberg 535 magazine choke tube.
Not as easy as it looks on the video
Watched the video,followed the instructions, and proceeded to get an education. Used on an 870 express that I've had since the late 70's. Well oiled both tool and mag tube, which was clean, put it in, it stopped, Got my small brass hammer , gave it a couple of light taps and it got stuck. Tried to rotate it free with the handle, no luck. Put the tool in a vise and rotated the gun and it came loose. Did this 3 times with a larger hammer and finally got the job done. Did not mess up the mag tube, I think I got lucky on that, all said and done the tool is way overpriced as it does not work as advertised and if you don't have lots of prior experience working on guns, and even if you do, this thing sucks.
Not for older Browning A5s
Brownell's should be specific as to what magazine tubes this will work on and sell some milled to specific tubes. Whatever magazine tube you use this one on; if you start driving this tool into the tube (even after lubricating both the tube & tool) and it comes to a dead stop: BACK IT OUT and do not re-attempt; it will get stuck and/or swell the tube to unusability. I had to put it on my lathe to bring it down to the correct OD (outside diameter) after soaking it all in Kroil overnight to get it out first. I'm a degreed machinist so I should've known to take a micrometer/caliper and measure the ID and OD of the tool & tube before using this. Don't trust this tool to be correct.
TERRIBLE- DIDN'T WORK
I followed the written and video directions to the "T." Despite oiling both the tool and the Mag Tube, the tool became horribly stuck in the mag tube. I had to totally disassemble the gun and use a wooden dowel to drive the tool out from the Rear of the gun (stock end). The dents were not removed as well as shown on the video, in fact, the dents became misshapen and exaggerated on the outside of the mag tube. I had to use a Foredom tool for almost an hour on the inside and outside of the mag tube and then had to re-blue everything. What should have been a 20 minute job, turned into an hour and a half nightmare!!!! The customer's BBL now is difficult to install and remove, but can be done without tools. Next time I will try using a heavy red grease and not a light gun oil!!!!! We'll see....
The video is deceptive on ease of use
I got this because all and all it's the best means for a non gunsmith to remove dents and dimples from a mag tube, that being said it functions nothing like Brownells official video demonstration. Per the instuctions I coated the interior of the mag tube and the exterior of the raiser with gun oil, as I started inserting it the raiser got stuck. Brownells has no troubleshooting guide nor any proper means of remedy so I had to improvise with a steel hammer, 'nail strikes' had no noticable effect so I had to use 'anvil strikes' in order to completely insert the raiser into the mag tube to facilitate removal. Fortuneately the tube was not damaged and what I sought to remove had been resolved, but when I reassembled the weapon I found that the mouth of the mag tube had been slightly enlarged, the action, barrel, and mag cap took effort to reinsert. The fact that the mag tube's diameter would be affected with use should've been disclosed.
