In case anyone will be sbr’ing their ps90...cmmg barrels are no longer chrome lined and are now melonited (I found out the hard way and their website is now updated as I had to call and advise
 ).

Cheaper manufacturing process for the same money.

Sorry to bring this back from the dead, but I just got one from Opticsplanet and it's chrome lined 4150.

Thanks for the heads up. I have had my form 1 for 2 years now and have never gotten around to finishing my ps90. Now, because of you I am $327 poorer and my barrel and adapter are ordered. FYI, save 10% by visiting this thread first.

Quote HistoryQuoted: Is that shown on the packaging? Just wondering because I just ordered one. M = Magnetic Particle Inspected P = Proof tested C = Chrome lined This is how CMMG marks their barrels. I also checked the bore and it is definitely chrome lined. |

All current barrels from CMMG are non chromed...this is direct from CMMG. They changed the description on their website because of me. If you are purchasing a barrel I would verify if possible that it is NOS chrome lined.

Just purchased CMMG 10.4 assuming that I would get a non-CL barrel and got a CL one (clearly marked on label and also on visual inspection). It was new and appeared to be drop shipped from a distributor. Didn't even think to check until I saw this thread. The chamber doesn't appear to be CL though, unlike the FN factory PS90 barrel.

Quote HistoryQuoted:
Honest question, why does it matter? I'd prefer a nitrided barrel, tbh; 5.7 is a pretty accurate round, and chrome is simply harder to plate without tweaking the rifling/crown and hurting accuracy. Both will eat full mag dumps in succession without any issues well after the front end is burning. It'd be nice if they dropped the price accordingly...but it's probably only a couple bucks difference at the very most anyway (nitride is one of the cheapest/toughest steel finishes, and chrome is one of the cheapest/toughest hard metal platings you can do). The kinda sucky think about nitride is it requires heating the barrel to about 1000deg for a good bit of time, which can really play hell with tempers...but barrels are only a few steps above dead-soft, so it's less of a drawback in this case. But really not something you want to do to a bolt head, for example (though people insist on it) |

How hard is it to install the CMMG barrel on a PS90? Is it something that should be done by a gunsmith, or is it the sort of thing that any competent tool user should be able to do?

I just received a barrel from Optics Planet and it appears to be chrome lined. Barrel is marked MPC and the label on the packaging says 4150CMV CL. Based on the listing price I'd guess they're trying to get rid of the old stock for the new barrels.

^^^^just checked mine and the tube has the same sticker exactly. I got mine from a dude on GB, he had 10+ in stock and a lot cheaper than anywhere else
except maybe Tombstone Tactical, $238 plus ship. |

I can’t sbr my ps90 here but would like a chrome lined barrel for when I move and I can’t obviously cut my barrel. I was waiting to buy one after I moved but it sucks they did away from the chrome lined barrel. |

Like the guy that posted after you, I got mine from ecpfirearms, he must have sold them all because it's not listed anymore. As far as chrome lined no idea, but there are a couple places that have them in the $250 range, Tombstone Tactical and Locked Loaded, I've ordered from both these places before and had no problems. Everyone is swamped so if you do order don't expect to get it for a couple weeks at the very least. |

Got it at FN Specialties- Threaded shroud for 16" barrel This would allow you to shoot suppressed but with the normal length barrel |

Can’t shoot surpressed in IL. I’m going to go broke getting tax stamps when I move. |
