Heavy duty, well built BCG
I got this for a .223 build where I used Aero Precision Upper & Lower.I grabbed a BCM charging handle & buffer tube assembly as well.The bolt is heavy duty & machined with tight tolerances.I didn't want to buy a bolt, carrier, extractor, etc. so this was my choice for a drop-in BCG.The bolt was tight when new and has worn in slightly with use.No heavy wear spots noticed after 1000 rounds fired and it cleans up nicely.I doubt it will ever break or wear out.Would consider another bolt if tr...Read more

Awesome BCG
Arrived in great condition and in a box and nicely packaged and oiled up really good.This is a pleasant surprise unlike the Colt BCG I ordered previously that came in a bag and hardly any wrapping to protect from drops etc.

Best BCG
BCM makes arguably the best bolt carrier group there is.Complete milspec for the most proven design you can get.Staked well, chrome lined, HPT/MPI, full auto profile, carpenter 158 steel, the list goes on.This checks every block without unnecessary coatings, lightening cuts, or any other less proven gimmicks.The bolt and barrel are the heart of an AR.Don't cheap out on them.

I couldn't agree more with Crippleshot!!
If you look closely at desert viking3's pic's you can clearly see the "M" in BCM is worn away.At 200 rounds that just does not happen unless there is some heavy metal on metal contact going on inside his upper receiver.There is also a deep scuff right below that broken key screw and damage from the center of the recess to past the rear key screw all along the side.If you look even closer, some of the tops of the forward assist teeth are also damaged.It looks to me that it has to be from some...Read more

Doesn't interact with a lower so sure you can use them together if you have an upper that will fit/work with both. Which should be most uppers.
