I purchased a older used Colt upper off of Gun Broker.com, it looks like a SP1 with forward assist, I am wanting to install it on one of my Rock River lowers I own. The Colt upper I purchased did not come with a bcg, can I just purchase a semi bcg from Bravo Company, or LMT? Will i need to purchaes head space guages once I have received my new bcg to make sure it safe?

New bolt in a used bbl will work OK. New bbl, old bolt is a no-go.

It's a good Idea to have a Field Guage atleast, or try to find a member close to you that has one and meet up with them.

Thank you guys for the help!, is there a kit that has all 3 guages? "go, no go, and field", or do you have to purchase each one individually. I have looked on the DPMS web site and they show several different options of guages, some under thirty each, and some over forty each, i am confused on what ones i need.
