I have seen some BCM Buffer Tubes drilled rough and too deep.

The BCM will be made from the proper materials though.

Thanks for that clarification. It would seem to me that a different caliber could fall into the "copycat" bucket. Further reading needed on my part.

One nearly needs a lawyer specializing in MD firearms laws to own/build/modify these black beasts.

BCM is good, just telling you to physically examine the bore and check bolt travel as my video shows. No matter who makes it.

If the spring is suspect, and want standard springs Colt is the way to go. They are called action springs by colts nomenclature. If you want an improved life spring a Sprinco spring or Tubb spring will last the life of the weapon. You have to be sure you have a smooth buffer tube bore in order to use a Tubb Flatwire spring.

You may run into issues with NiB and the Criterion barrel as well as gas key issues. Those require gauges to check though.
What is wrong with Spike's buffers? I've used quite a few over the years on personal builds and haven't seen anything suspect. Am I missing something?

The powder is less effective compared to solid weights.

Thanks for all your help! Got everything together but needed to order the colt h3 buffer. So once that is in I will measure the tube like you showed us in ur video and but it the rest of the wsy back together. Then go shoot it.

Quick off topic question about my hand guard! It's a cheap one just made out of 6061 t6. But knowing that some are polymer it should not be no big deal right? It's not like I need to pull it off and go looking for a bcm 7075 or something. Did not notice it till I pulled everything apart and saw what it was made of on the inside.

As long as the rail is tight/secure and trued to the upper receiver you are fine.
