Pof roller cam pin

I dont like how a squared headed cam pin eats away at the upper. I have a dome lantac cam pin in my stag 10 and it has zero wear in the upper in the cam pin slot. My ar15 is chewed up from the square headed cam pin it has.
I'm building another upper with a jp bcg and it has a square headed cam pin and I dont want it chewing up my upper. The pof roller is supposed to stop it from taking out aluminum in the cam pin slot.

I think you are worrying about a non-issue but, I do the same sometimes lol. In fact, I was all set to buy a POF roller for my Stag 10 build earlier this year. After a bunch of reading I decided against it as most concluded it is just not needed. Cam pins/channels wear in(just like most moving parts on a firearm) and then the wear declines dramatically. Using a high quality gun grease or thicker viscosity oil on the pin and its channel is still a good idea though.
My understanding is that the POF roller cam pin was designed to deal with the higher side loading put on the pin caused by a piston system. And, even then they dont seam needed as most piston guns apparently run just fine for 10 of thousands of rounds without them. Standard DI guns should(do) run even longer. There was a post a while back about the lifespan of various parts on various AR platforms. The info was sourced from a Las Vegas rental range that ran mainly full auto. Trust me, if you read it you would realize that the cam pin and channel in the upper are not something you need to worry about. It is pretty amazing how long these things can run even when being abused at a sand filled full auto range by amateurs.
With that all said, I decided not to get the POF pin(not a finance based decision) but, it sure isn't going to hurt anything other then your wallet. So, if you want one and want the least possible wear, then I would still get it. By the way, that Lantac one looks pretty nice, thanks for the heads up about it.
Keep in mind, I believe the gas key must be removed to install it. Then you must re-stake it of course.
Dealing with your actual question, if putting this on a AR-15 BCG, yes you need the new gas key that they make, if putting this on an AR-10 BCG then the gas key is not neccessary
Thank you. This is what I wanted to know. It would be an ar10
I really like my lantac. Its heavier than most and gives me a long lock up time. And I'm convinced a longer lock up improves accuracy. The domed cam pin hasn't made a mark in my stag 10 upper and I have close to 700 or more rounds on that upper and barrel, some of which were hot enough to pop the primers out of the cases.
I've been looking at the JP FMOS or VMOS bcg with high pressure bolt for my next build. According to most sources it's the best bcg on the market right now. It's also a few ounces heavier than the lantac ebcg. The only thing I dont like is the square headed cam pin.
The weight of it is what caught my eye for building another sub moa gas gun. It's just that cam pin that I dont like about it.
