How to Polish a Feedramp Quick and Easy

Hey Guys so i just uploaded a new video on How to Polish a Feedramp Quick and Easy. I like doing this small modification to my firearms as a preventative measure for failures to feed that can be caused by a rough Feedramp in which the round gets stuck riding up the ramp into the chamber, and also to make easier cleanup for powder residue as it does not stick as easily to the polished surface. I hope you guys enjoy the video. please hit the subscribe button to help support the channel and to keep up to date on all the new videos i upload to the channel. Thanks again everyone for all the support.

I have been doing this, with all my auto loaders, for about 35 years. As stated, it is a cheap but productive way to aid in the reduction of common failures, like failed to feed and failed to extract.
For those that are not familiar with the Brownell's polishing compounds, or others like it, you can use Dupont automotive polishing compound. It is a little more forgiving, than the dry type and still produces exactly the same end result. I use a common Dremel tool, as opposed to the air tools, but, again, the end result is the same.

That is correct, outcome is the same, I have people that I know of the at do it with a wooden dowel and sandpaper and just work their way up the grits. Smooths it right up.

I had not considered polishing the inside of the chamber, but it makes sense. To polish the feed ramp, I use a HF micro air die grinder (p/n 60244) that runs up to 56000 rpm. The pistols I have are stainless steel so for compound I use the stuff I have for polishing s.s. trim on older cars. Thanks for the great video.

Another thing you can do to make feeding more reliable is to radius the chamber mouth at the top of the ramp/bottom of the chamber. when I do this I use the cratex rod abrasive and the easiest way to do it is to simulate the path of the bullet up the ramp. At the point where the ramp breaks over the chamber mouth, you simply rock the cratex over this edge which rounds that edge slightly. The secret is to remove the edge without removing the support. This goes a long way toward elimination of feed problems with hollow point ammunition in a semiautomatic pistol.

For those who may not be familiar with cratex, it is a rubber and abrasive product that comes pre shaped into wheels, rods, cylinder and bullet shaped points. Available in a lot of supply stores, here's the one I use -

You can use the cylinders to jewel bolts and flat surfaces on firearms, (it does a great job on the sides of revolver hammers and triggers), and it comes in various grits. I prefer this type because it does not throw compound all over you and your shop. I use a variable speed moto tool, and I also have a Foredom flex shaft tool and the slower the rpm the better - you will not have control at 15,000 rpms, where 200 rpm will do the job.

I highly recommend performing this operation on any semiautomatic pistol. The increase in reliability and in ease of cleaning is well worth the effort.

pbsdaddy - Same for me brother! I don't know why people think a manufactured product should function flawlessly when they are not hand tuned and fitted. I don't get disappointed when a new firearm has a problem, I just fix it. That is why most gun reviews are bull. They either get a massaged sample to evaluate, or they get hung up on a problem that takes 20 minutes to fix and then give poor ratings to it.
