Purple BCM upper?? > AR Discussions

Posted: 10/18/2013 10:13:50 PM EDT

Took delivery of a new BCM upper receiver last week. Looked good out of the box, but today when I took it to the range it was damn near purple in direct sunlight! LOL. Don't care much myself about looks/cosmetics, but definitely found it odd coming from a manufacturer with such a good reputation. Perhaps they should list these uppers as their "Rodeo Drive Camo" receivers?? Haha. Has anyone else had a similar experience with BCM upper or lower receivers?

It happens. Older Colts are famous for it. In fact the last few lowers I picked up from PSA had a blueish look till I coated them in CLP and let them cure in the sun for a few days.

I've had the same experience with model 1 sales uppers. I also shot and oiled them well at it went away quickly.

my Bushmasters are purple but my BCM's have a nice dark finish......

I had an FN upper that was extremely purple. Its the anodizing process, sometimes the colors are hard to nail down.

Functionally, it has no effect on the longevity of the finish. Cosmetically, youll find that some folks dont like it, and it affects the resale value.

Have a purplish (relative way to describe it) lower but I did notice that I don't notice its color much when I am shooting it.

I really like the purple, especially on 20" A4 rifles. Issued FN's have been notorious for the purple anodizing. I think it looks pretty cool for a clone.

They are the new Bushmaster.

LOL. Gonna paint it Atacs-AU, so not a big deal. Just found it surprising that it passed QC/QA. Thing shoots like a wet dream though so definitely not sending it back!

Just had a bcm upper arrive yesterday that was purple. Looks funny with the fde ris rail. I'll end up rattlecanning when the build is done though.

BCM has stated in the past they don't make "pretty" parts, they make reliable, combat ready parts.

That's where they get their reputation.

Purple tint in anodizing happens sometimes.

I had a colt 6920 that I ordered earlier last year that showed up looking like a purple Dinosaur Barney gun. It was real stupid looking. I traded it off for a really nice 1911.
