I understand stripped and that is what you are getting in return.....a new melanite well finished stripped full auto cut Carrier with the Brownells name behind it, unused......who made this Lo Mass carrier and how used is it??? and just so we are clear the GB is a new in pkg non adj. Aero Precision low profile non adj Gas Bloc Melanite and what are the particulars on this SLR adj. gas block????
I was asking (if needed) impute on buffer and spring mods etc when I set this one up......I understand the concept of the lo mass carrier....just have never ventured into one.....just have read a few texts you have on site...no experience

Both are used less then 100 rounds. Will clean them before I ship them.
Lowmass bcg is righttobear.com's in-house bcg.
No need to change buffer weights are springs, standard buffer and spring is all I use in my rifles with lowmass bcg and adjustable gas.
Will PM you my address in the morning, tired just finished preping and priming 600 plus peices of brass.

I just measured my Bolt, from Buds Gun Shop( Brownells) and it measured 2.800 and my firing pin is 3.265 I have fired just over two hundred rounds( all Hornady American Gunner) through my rifle and I have not had the single malfunction or punctured primer as of yet. All AR bolt carrier groups have a free-floating firing pin anyway.

Looks like your firing pin and bolt would be within the .008 tolerance for firing pin protrusion. As long as you keep this bolt and firing pin as a set you should be gtg. My eight AR-15 firing pins measure between 3.274 and 3.280. These are from my 5.56/223 AR-15s (2.800 length bolt) and my 6.5 Grendel AR-15s with 2.810 length bolts
