Questions & Answers
i have a gas impingement DPMS LR308, will this just swap out with square cam pin without gas key change out? Confusing. Expert Answer

The roller cam pin can work with direct impingement, but the gas key needs to be swapped. If the mil-spec gas key is not replaced, disassembly of the bolt carrier group will not be possible.

Can I use this in my Direct impingement gun Expert Answer

Yes, while POF USA does say it's for piston systems on their site, they do say in videos on their Youtube channel that the system can work with a DI system as well.

308 Roller Cam in JPLMOS by Scatter, May 15, 2022
Used with JP Low Mass DI AR10 Bolt Carier Group. The combination is smooth as butter and works great. No need to remove the gas key on a large frame, drop in replacement. Used to improve the life of an upper reciever.

Smooth cycling by Jack, Verified Owner, December 3, 2020
I only had about 300 rds through my Brownells BCG when I noticed a sharp visible gouge on the cam pin where it normally wears. The carrier has sharp unfinished inner edges which are doing the damage. I bought this cam pin and cycling does seem smooth...

POF roller cam pin by John, April 4, 2020
Exactly as advertised. Beautiful nickel boron finish, heavy duty, high quality alloy steel construction and smooth, reliable operation. This is the upgrade every AR variant firearm should have. I will be installing these in all my builds.

Well Made... by John, Verified Owner, October 8, 2023
Compared against a standard pin that had its contact points smoothed and lubed the Roller Pin has a slightly easier feel when using the charge handle to unlock the .308 bolt. Because it is a bearing I packed the roller with a light grease. It's a kee...

Reduced wear on large caliber AR platforms by tsw, Verified Owner, February 17, 2021
Great for reducing potential issues and wear on large-frame AR rifles. AR-10s are known to have issues with overgassing and excess carrier speed, both of which can accelerate wear on the upper receiver cam pin channel. This replacement part helps by ...
