Have a 3 year old model 811000 that runs like a Swiss watch, been very pleased with it. Shoot steel cased ammo almost exclusively, and have put about 3k rounds down range. I know eventually I'm gonna have to replace the extractor and spring assembly, so I'm looking to find a kit that will work every bit as well as my factory parts. Don't need to replace now, I just want to have the parts on hand for a backup, will probably add a firing pin to the extra parts list.

After doing some research, I came across this from Bravo Company -

BCM SOPMOD Bolt Upgrade Rebuild Kit

Has anybody here with an MP-15 used this BC kit for replacement parts? Is it overkill for our MP-15's or will the less expensive parts from let's say Midway or Brownell's suffice?

The M&P bolt is high quality, from a reputable source and was assembled with similar quality parts... came with the o-ring and the black insert from the factory.

So no, I don't think that is overkill. The Del-ton kit is $10 less, and the DPMS kit is only $1.50 less on MidwayUSA.

Thanks, Cyphertext......Just ordered one to throw in my rangebag. Nearly all the reviews and info I found about this replacement kit highly recommended it.
