Hi, New to Ar15. Been running my DPMS 16" 5.56 1.7 twist. Lubed from new with Slip2000, always run wet. Started getting fails to extract and fails to eject.
Stripped down only to find BCG would fall off the bolt doing the drop test.
Only fired 1500 rds. I have seen other posts on AR15 archives with folks having similar problems as me, on a wide range of makes.
The common factor seems the use of slip2000.
Anyone else out there had similar issues.
I am now switching to mobil 1.

I agree with the last post, it's probably not the Slip2000 at fault, probably a burr/rough inner bore ate the rings. Look up filthy14 used by Pat Rogers at EAG, and all that was used on that rifle was slip2000, at last count was 44,835+ rounds (a BCM middy) and back in BCM's hands now I believe. I really like Mobil1 as a lubricant, but I also use Slip 2000 with fine results.
There are sometimes weird coincidences that lead us to strange conclusions (I've done it), I do not think Slip2000 can be blamed for gas ring failures with regular use. Look for Filthy14 data, is an interesting read.
Edit to add--> I looked for info on Filthy 14 and corrected my number, as of last week the round count was 44,000+ per Pat Rogers.

OP, have seen rings go fast in a few newer BCGs, first set. Maybe you received soft rings, or slightly rough bore on the carrier. Maybe a bad batch of Slip2000, but unlikely. I am big on using Mobil1, it works. But I still believe Slip2000 is a good lube that stays pretty wet in my uses. Good luck with figuring this out.
