No Logo. It is a problem. It is a real problem. I can not find a difference between half of dozen of BCGs I have without seeing some markings on carrier. Why don't they put some littler mark with model number to know what I am holding in hands.

I recommend using your own color code. You can place a small dab of colored paint in the bottom of the hex wrench slots of the gas key screws.

Most of the people that are considering purchasing these over priced BCGs don't know that most of the problems they will encounter with BCGs can be fixed easily, with less than $4.00 worth of parts. Most of you would be better served by putting together a "BCG FIRST AID KIT". made up of the component parts that are most likely to fail, or degrade. You can start for under $20, with a couple of extractor springs, extractor spring inserts, two sets of gas rings, a firing pin retention pin, and a extra buffer spring. All of these items are currently available, and should fix 90%+ of the BCG problems you may encounter in your next 5000 rds. If you feel the need to be more prepared for some unknown future event, like a zombie apocalypse. You can spend an additional $35 on these items: extractor/with pin, ejector/with roll pin, ejector spring, firing pin, and cam pin. We all need to shop smart, and not feed the greed, so if you can't find these items at close to the prices I mentioned, feel free to message me for assistance.

I just received my $15 e-gift card from Brownells 7 days after the purchase of the TIN BCG.

Same here. Just got BCG with no card.
Just got off chat with them. They said they were a little overwhelmed and were behind sending out gift cards.
Said I should get e-card by email hopefully next week.
Nice BCG, would probably buy another if I was sure they are going to send gift cards.

The following quote comes from a June 2018 review from Abe's Gun Cave. "Every so often, you find a great product at an incredible price and that is the case here. The Brownells M16 BCG is hands down the best AR15 bolt carrier group (for the money) I've ever seen." I agree, that for the money it is the best BCG I have ever seen.

Deal. Love the nitride treatment, this BCG
has great recommendations going for it,
not to mention the price & $0 shipping when
you get like $1 more stuff on the order.

Ammo on sale? Check.
