At Charlie's Custom clones, we are a little picky about our bolt carrier groups. We are used to seeing failures in the past, and Daniel Defense makes one of the better BCGs on the market. There are a handful of great BCGs to pick from, but this is top shelf. You cannot go wrong with DD. Daniel Defense has one of the best milspec BCGs on the market, and the DD brand on the BCG. There is just no way you can go wrong here.
Note: offered new in retail packaging and also in bulk packaging. Some BCGs have been test fired by Daniel Defense for high pressure testing, and may show brass on the bolt. Only fired by Daniel Defense, not used. As we get both bulk and retail packaging, and that is often at the manufacturer's discretion, we cannot take requests for one or the other. Both are the same item. One we keep in our warehouse and the other in our workshop.
