I've found using an NiB cam pin negates much of the wear. LWRC probably has the cheapest for about $11. Mine is either a Fail Zero or a Spikes (can't remember). It has very little wear on it after several thousand rounds. Also, I lube with Aeroshell #7 synthetic EP aircraft grease, so I'm sure that helps as well.

I am running some Colt ones and have a bunch of BMC replacements. I want to run them some and knock down the sharp edges and then send the bolt carriers out to Robar to get one of their NP3 coatings done. The only thing I am concerned with is the small bleed hole getting blocked during the coating.
Has anyone had their enhanced carriers plated?
On another note, I received (3) new enhanced bolt carriers from LMT yesterday. First off the finish is now smooth. The last ones I got had a rough/textured finish. Some of the machine work seems to be more refined also.
They are still using the (3) main holes, (1) tiny hole, and then the 4th hole -
Gas key is staked. Allen heads are somewhat stripped out, wish they used a better quality bolt. I do not believe this to be a MIM key as it does not have the mold marking -

Might still be a MIM key, just with the mark somewhere not visible.
Also, LMT's constant, unannounced iterations to these things breaks my heart. I feel like I'm buying electronics that get outdated in 6 months.
Kev,
Do all three of the Enhanced carriers you received have stripped out gas key screws, or are they only stripped out on the one pictured?
Also, are the gas keys chrome lined?
I bought (3) of them, (1) for me and (2) are for friend. They are all full auto carriers. I just grabbed one out of the box for myself and that was the one I took the pics of.
Top to bottom, (1) two year old SA enhanced carrier, (2) brand new FA enhanced carriers. Note the difference in texture -
The gas key bolts on these are not stripped out like the other one -
All of the rear bolts have some slight distortion but are not stripped like the other one. When I first glanced at the other one I though LMT went to torx bits. You can also see the mold marking on the last one.
None of the gas keys are chrome lined -

Thanks for the pics.
I purchased an LMT Enhanced FA BCG around September 2011 and it had a very rough finish, it also had both gas key screws stripped out.
I had no confidence in the torque that may not have been applied to the stripped out gas key screws so I replaced the key and screws with a new set from Bravo Company.
I also sent that carrier off to get the NiB-X finish from WMD Guns, which did not block off the small vent hole to the rear of the three vertically aligned main vent holes.

I had one come in from LMT this week also, it is as yours. The rear gas key screw is a tad boogered up, the front one is not. Also no MIM ''dot on key, but it is black inside so I assume that it is MIM--- OK with me. I had ordered it about a month ago, so they appear to be getting back in stock a little quicker.
