Anyone have any experience with th POF roller cam pin? Will it fit my SR556?
I picked up a few at SHOT, I’ll be taking a look at them in an upcoming review.
The roller cam pin from POF has functioned as advertised. I have not personally tried it in any other piston rifle but I have heard and read about people who have used it on an SR556 and others. I don’t think you can go wrong with it if you are experiencing any upper receiver wear on your SR556 and the price is reasonable IMO. Good luck.

I would like to hear your review sir. I went ahead and ordered one. Also if you had time I have an idea about a way to make DI ARs function when submerged. I may not have an original idea but I might do.
Im not experiencing any wear on my second SR or any other problems for that matter just a premptive measure
Install it on your rifle and run it. If it runs, then it is a good preventative measure. I hope it works out for you like it has for others.

Thank you O. I think anything POF makes is dang good I just wish I could get my hands on one of their charging handles.
I’m using these in one of my Rugers and also in my PWS.
The Ruger had probably 1,500 rounds (and some pretty good cam pin wear) when I installed the POF cam pin. I’ve only got two or three mags through the rifle since but I don’t notice any additional wear.
I had 100 rounds through the PWS and it was showing the start of cam pin wear when I swapped cam pins. I’ve got an additional 100 rounds through the gun (on full auto) and notice no additional wear from the initial mark made by the solid cam pin.
Granted, neither upper has many rounds downrange with the new cam pins installed but they seem to work as advertised.
SHOULD THIS ONLY BE USED ON A PISTON GUN
Awesome, how has the Ruger been working for you? I had to send my first one back and if the carrier tilt on this one gets much worse Ruger will be hearing from me again.
Yes. Unless you want to remove your carrier key in order to install it. Then after reassembly you can’t field strip your your bolt carrier group.
POF’s got a new modified gas key that’s cut to clear the roller cam pin.
Accurate and reliable. The one I’ve been shooting is actually one I bought used off gunbroker. I bought it while my first original gun was back at Ruger getting replaced for carrier tilt.
The PWS upper causes carrier tilt too. I thought their system using the long piston was supposed to change the balance point of the bolt carrier and keep the carrier from tilting. Not true…
OH SNAP !! I know what I am going to have to try out.
Not to be negative, but if cam key wear is a concern( piston rifle or not, I know people have found identical wear on DI rifles), I’d rather shell out $10 for the LWRC beveled-edge Improved cam pin than pay $70 for the POF roller cam pin AND relieved gas key, and have to restake the key. That said, I actually like the idea of the roller, just not the overall price and work involved to eliminate that kind of essentially negligible wear with the POF parts. I also would prefer not to pay the big $$ for IONBond or Failzero Bolt carriers, and the having to change out to a hard chrome key.
Thanks for the heads up. Have to check it out.
I’ve got one in my DI rifle - the roller bearing reduces the friction between the upper and cam pin when stripping rounds from the magazine… Huge little reliability upgrade in my book.
The idea behind it seems sound. Whether or not it adds anything to the overall reliability remains to be seen.
Still, I wonder why nobody thought of it years ago.
I still dont understand how it functions differently than a standard cam pin…
Instead of just a standard cam pin it is a ball bearing roller.
