Grind is a harsh term, but yeah... I do it.
I also polish the offending areas around the gas key using the same tool (Dremel). |

When using a rotary tool an assortment of polishing bits provides a great finish to a little bit of grinding. Near mistake-free and very forgiving. https://rover.ebay.com/rover/1/711-53200-19255-0/1?type=3&campId=5337559805&toolId=10001&customId=izn4m561qq00zk8a00004&mpre=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fsis.html?_nkw=Dremel+462+Set+Mounted+Rubber+Polishing+Points+Bullet+Cone++PREMIUM+USA+Made+5pc&_id=321746775735&&_trksid=p2057872.m2749.l2658

I mentioned why the POF cam pin is better suited for the piston because of the removal process for the gas key. If you want to take apart the bolt after installing the POF cam pin, you need to remove the gas key again to take apart the bolt itself. Now the other roller cam pin that I mentioned is out on the market and I do not remember the company name. It is a three piece unit that can be removed and installed into a normal bgc. It is similar to the POF concept and I believe it is either the same price or cheaper. If you want a roller cam unit, I would go with this one. The good thing about the roller cam is that it is easier to me to move the charging handle. The roller cam does make the bcg movement much smoother. But that is just me. |

You say it's smoother but how would you ever feel it? The only time it has any pressure against it is when the bolt is stripping an round out of the magazine. During the unlocking, extraction, and ejection portion of the stroke there isn't any pressure against it because it's rotated away from the receiver interior. If the rifle is unloaded it has no pressure against it.

I remember a few years back Dano (moderator from the troubleshooting forum) made a really good point on this subject that for some reason stuck with me. After you can already see the wear in the receiver, it wouldn't make any sense to smooth out the cam pin because the cam pin already made its path in the receiver. I guess I could see it on a new build tho maybe. Its not something I worry about personally tho as I'm not the type to worry about scratched up anodizing |

When it goes through the anodizing, you be a little concerned....
Anodized aluminum is has hard and almost as wear resistant as good steel, bare aluminum is soft. And, since the cam pin is being pushed to the left during feeding by the cam path, the groove in the upper will only get deeper. After a point the bolt lugs will start to hit the lugs on the extension. |

You don't think the rails on the bolt carrier and receiver as well as the cam path in the carrier itself would keep the cam pin from cutting further and further left over time? I haven't inspected it this close but just picturing it in my head I would think the carrier/receiver rails as well as the cam path cut in the carrier itself would limit the deeper and deeper cutting |

If the cam groove in the carrier moves the pin in such a way that the head of the pin runs into the upper, after a bit of wear, that should stop. There isn't a lot of "slop" in the carrier's camway, and it should remain very consistent in exactly where the cam pin head goes.
Then there's the cost aspect. A stripped, forged upper can be had for less than $50, or around $65 if you're picky about brands. A complete BCG costs anywhere from $90-$180 (again depending on whether you're picky about brands). IF the wear in the upper gets to a point where the weapon fails to function, it's a $65 fix. |

The cam pin head doesn't even touch the receiver while you are retracting it. Bolt rotation during the unlocking and extraction phase is accomplished by the cam cut in the bcg, not the receiver cutout. So if it isn't even touching how can it make this feel smoother? The cam pin head only contacts the receiver wall during the loading phase. Pull the handle back and let it fly. You'll never feel the effect of that silly bearing. |

I don't know about rounding the corners but I have the POF roller pins in three of my rifles and that addition did smooth them out. If your gun is a piston- you can probably drop one right in. On my Wilson- I had to grind the stakes out but the kit came with a new key (the key came relieved for future removal) and bolts. I have one in a Ruger 762 that's got over 1k through it and the inside of the upper is barely marked. For the money involved- I'd do it again.

The cam pin head only contacts the receiver wall during the loading phase. Pull the handle back and let it fly. You'll never feel the effect of that silly bearing. I am going to make the easy. The only time I have seen a strange problem like this is on one specific type of upper: the TD-415. I asked for help on the piston forum and another guy that encounter the same problem on his TD-415 and offer his solution. That solution worked at the time was the POF roller cam pin. I believe POF was the only company had built something for their own GP BCG and piston rifles. This was just a simple low cost solution for a strange problem than wasn't making conventional sense in pinpointing the problem. The reason why I stated that the POF roller cam is better suited for a GP BCG because there is nothing blocking the removal of the roller cam pin. On a standard BCG with the gas key in place, you are not going to be able to install or remove the POF roller cam without removing the gas key and screws. This is why I stated that the POF roller cam is better to be used on a GP BCG. Plus, POF has this warning in their instructions for their roller cam for use on a standard BCG. Because the POF is finished in NP3. I believe this helps with the smoothness of the roller cam pin during the cycling operations. Going back to the Hydra-Fire cam pin. I do not have any experience with this product. The only thing I do like about it is that it is able to be installed on a regular BCG without any mods to the existing BCG. Does this means I am going to buy one right way? No, I do not have a need yet for such a thing on my standard BCGs. If I was going to buy one, it is just going to be for my testing and to see how well it holds up. Since I'm not planning to build anymore projects in the near future, this option is going to be in the back burner of my mind. Feel free to IM or email me if you got any more questions. |

The POF and the Hydra-Fire address different points of friction. Are either needed? No. But both of these products do reduce friction, just at different points. Now, I do shoot my guns and I don't round off cam pins. But I have installed several POF roller cam pins and one Hydra-Fire cam pin. Once again neither is required in an AR15. The POF works better in piston guns because in my experience the wear inside the receiver is worse in a piston system than in DI. The POF product specifically reduces friction between the head of the cam pin and inside of the receiver. If there is any contact during cycling then this will reduce friction at this point. The Hydra-Fire does NOT address the wear between the cam pin and upper receiver wall directly except in that the head is rounded, but the head is fixed. The Hydra-Fire is designed to reduce friction between the cam pin and the slot in the bolt carrier. Generally less friction is a good thing, but this does take one part and turn it into 3 parts. So it adds complexity. So far I have about 4,000 rounds on the Hydra-Fire with no issues. I'll run it in most of my AR test platforms until it breaks, and report on it with a brief video at about 10,000 rounds.
Here is my video comparison of the two products if you want to check it out. https://youtu.be/llOnufQ1zrY |

Thank you for the very informative video. I just bought one of LWRCI's di gun and installed a POF roller in it. It was possible due to heir use of a seperate tube for the "snout" of the gas key. It's threaded and pinned in place but removal is simple enough. I enjoyed your comparison of the available options. Thanks again.

The left side of the cam pin channel carries the load. The right side does very little. The area that takes a beating is the very entrance of the cam pin into the channel when unlocking. Any slight misalignment and the corner of the pin pounds against that area. After it takes a set. it usually stops. Bolts rotate 22 1/2 degrees in the carrier. The lugs actually disengage the extension at 21 1/2 to 21 3/4 degrees. The cam pin is not exactly in alignment with the channel, and bumps itself into alignment. Piston rifles are a little worse here because the movement of the carrier is not as positive as the DI gas extension. Even DI wears a little. I machine a 45 degree angle on the corner of the cam pin, and a corresponding entrance angle in the cam channel in the upper. It stops about 80 percent of the beating, but there is still some. On piston rifles, some use a spring in the carrier to help completely extend the bolt. It helps some. Regardless, you will get some wear no matter what. I do not care for roller pins. I have seen them come apart. The wear is more cosmetic than anything else.Most shoot their rifles and never even notice it.When someone finally does, they think their rifle is failing. When you tell them it is normal and not to worry about it, some think you are an idiot. Craig

Not using piston guns, not over gassing guns, and using uppers with the proper material; should make it a non-issue.
Travis Haley mentioned having 40k rounds on one of his barrels. Thinking it has been on that gun the whole time. He didn't go into details but sounded like it, and didn't speak to anything breaking or wearing hard. It'll work dirty, but clean it when you can to avoid extra wear. Good oil, no WD-40, etc. I'd have to look but I'd think rounding off the corner would change the cam path. I'd avoid doing that. |

It'll work dirty, but clean it when you can to avoid extra wear. Good oil, no WD-40, etc. I'd have to look but I'd think rounding off the corner would change the cam path. I'd avoid doing that. When I talk of putting a slight radius on the head of the cam pin I am talking of a small radius, 0.015 to .020 not much more that this: 
As opposed to this: 
It will not change the cam path, that's controlled solely by the carrier slot. |

This was another short, but enjoyable example of people worrying about bolt carrier wear as if they were about to blaze 10k rounds every 6 months or something. In reality, they will just take pics of their gun and put it away. Tier 1 cam pins can suck my butt.
There is no attainable advantage to rounding off the corners of the pin that isn't aesthetic, and the part of the carrier and upper that wears is on the INSIDE of the receiver so you can't see it anyway. |

the cam pin wear on the receiver. Why haven't they redesigned the receivers to have this wear pattern?
Just sayin'... |
