New build in process and a couple questions

Here is my parts list:

BCM complete lower with “H” buffer
BCM BCG and charging handle
Magpul MOE mid-length handgaurd
BCM/Troy rear folding sight

This will be used primarily as a HD/Range gun out to 300 yards.

Will a CMMG .22 conversion be okay to use in this gun?

Thanks for all the helpful advice.

I now have:
BCM Blem lower from Grant. (Great Deal)
BCM/Troy buis
Magpul Moe Mid Handguard
BCM BCG

Looking at a BCM Gunfighter charging handle. Just not sure on the medium or small latch. Any suggestions?

I decided to go with a 16" barrel instead of the 14.5" as my next build will be either a 11.5" or 12.5" SBR.

Any advantage of a lightweight 16" middy over the 16" standard ohter than weight?

Thanks again.

No, there is not.

Sure, but not as a HD gun. If I must shoot, I want all the power I can get.
