Ok guys, I'm pretty much done, Got almost 1000 rounds through it, added a sling, EOtech with GGG covers and throw lever, and Midwest trim ring, all total $2200. I'm loving it, and thanks for all the help in the past. I may be looking for a more high end bolt and BCG, if you guys can recommend some.

Very nice, benjandpurge. Looks like you have a great rifle!

If you do want a top of the line BCG I highly recomment Daniel Defense. I got one from gandrtactical.com for $129 plus about $7 shipping. Excellent quality and is fully milspect right down to the M16 carrier. BCM also is one to look at for about the same price. I think the DD is slightly better finished though. LMT is top notch as well but has a MIM carrier key that troubles some people though LMT claims it's better than other keys.

I put the DD BCG in my ArmaLite upper and put its original BCG aside as a more than adequate spare. Both have performed flawlessly but I do have more peace of mind with the most crucial component group being the best that money can buy. And having a spare of this most critical part.


ETA: Alas, they are out of stock now...

Ok, you echoed my sentiments, the more I have learned about AR-15s the more I see that the BCG and bolt being a highly crucial part in the equation. While my Oly is good I'm sure, I do also want that peace of mind. and having a spare is a good idea, I didn't think that far ahead. I'll keep looking around for the DD BCG, also what about Spikes, are they decent? They seem to be used alot as far as I can see.

I can only speak of Spikes second hand but many people include Spikes Tactical in that elite group of BCM, DD and Colt BCGs. The specs that Gate posted above are what you're looking for if you want the best.

Oh another thing about LMT that I forgot earlier, their BCG no longer comes with an M16 bolt carrier. Same goes for some Colt BCGs but their milspec ones are good. If you're after the best BCG you really want the M16 or sometimes called FA carrier as it smoothes out cycling operation. Though it is a full auto part the BATF does not seem concerned about it since it's in the upper receiver. They are VERY concerned about FA parts in the lower receiver!

Also an H-buffer with appropriate action spring is a good upgrade to "M4" carbines that don't originally come with one. Of course with any changes like this you'd want to be certain the rifle still is reliable with the ammo you use.

The hard part about all this is we're talking about a rifle - your rifle - that functions perfectly. It's hard to justify upgrading components but then peace of mind is important. Also, I suspect you're the kind of guy, like many of us here, who will build an AR down the road. That's when those extra parts in the parts bin really come in handy!

ETA:
This link details the lengths that BCM goes to in building their fine ARs. The 3rd post gets in to the BCG.
