Watching this build for sure.
Those are some mighty fine components too.
I had the barrel on My AR10 threaded, installed a compensator, looks almost like that one.
That compensator sure did change the way My AR10 shoots, along with the Geissele trigger, much more improvement.

I thought Colt went to Titanium on all full auto firing pins? is it coated or just ground and polished?

I can't really tell for sure, it looks like the same finish as the carrier and the rest of the pins. It doesn't have the same shine as my spare AR-10 firing pin. I should be able to tell once I get some carbon flowing! :woohoo:
d. wilson makes BCG's for several different rifle manufacturers, they call him the BCG Guru! He stays on the cutting edge but only does DPMS pattern stuff :(
I had a hard time finding an Armalite pattern BCG that was coated anywhere, same difficulty with barrel makers using the Armalite pattern extension. This led me to go with the DPMS pattern but I still have to find a rail I like with an Armalite thread pattern to match my upper.......
I maybe should have done my first full build on an AR15 but then I learned to swim in the deep end so what the hell! :usa:

It doesn't feel different than my AR-10 pin as far as weight goes, odds are it is a coating then.

Been reading about them. Looks like they have jumped in both feet in the high end high quality products. I am impressed by all that I have read, looking to get my hands on one someday...

Working on the road is a curse and a blessing. I have nothing else to do after work but post on forums, research, and buy parts, the posting and research are free so a blessing....the purchasing parts can be a curse, especially when the wife does the accounting! :huh:
I should be able to post pictures of the X-Caliber barrel this weekend, the wife said it arrived Monday. Odds are it will be at least a month before I get all the parts I need ordered. Still have to decide on a stock-buffer system and whether I want a standard or adjustable gas block. I keep hoping Iowa will pass the suppressor bill so I think I'll go adjustable but then I don't want to jinx myself :blink:
The handguard and all the goodies for it will be there when I get home, with all the extra parts and pieces I can set it up for about anything, :twothumbs: for BMS!

Along with the handguard from BMS I got my barrel back as well. Regretably the threads got buggered a bit from a whack received in shipping. It was hard enough to split the thick plastic cap they installed to protect them, :( I think I'll try to clean them up myself rather than ship it back again, X-Caliber has been very good to deal with so I'm sure they would handle it but I hate to hassle with it if I can do it. The chamber is very smooth and the bore is like a mirror with very crisp looking rifling. The crown looks very nice and I was pleased to see the dimple for locating the gas block position, one less thing I can get wrong!
