I mentioned in the other thread about my son and he said it would be alright if I shared what he is working with right now and he had some follow up commentary on the "throwing some shade" thread. He is currently assigned to Land Warfare in the USN. His duty weapon is a combination of a lot of parts and not an all original rifle. He has been training quite a bit for CQB and this is what he shared.
1) The lower and upper are both Colt
2) The barrel is a replacement, he thinks Lilja but it has been rattle canned and it is hard to read.
3) He has a badger ordinance gas block, DD is also common.
4) The rail is a DD cheese grater pic style at 12, 3, 6, 9. Some guys prefer a beefy mlok but he is not sure who manufactures it.
5) The flash hider and can are both surefire but he sees KAC commonly as well as a few others.
6) Iron sites are apparently optional, he has seen KAC (200 to 600) most commonly.
7) The stock and handgrips are all variable, it kind of depends on what the shooter prefers.
8) Usually the buffer system is H1 mil spec.
9) Most of the triggers are Geissle SSA
10) Because it is CQB, most of the sites are red dots and holos. The most common is EOTECH and Aimpoint. He mentioned that they almost universally use risers so that they can keep their head upright. Apparently several brands based on user preference.
11) They mostly use PEQs
12) Some like having an offset red dot or offset iron sites. The RMR is the dominant choice here.
I am pasting this part for y'all.
" I read the thread and other than a couple of people teasing about some very low end stuff, all the rifles are fine. I can't believe you sold the KAC and the BCM, there was nothing wrong with either of them. I have had two armorer courses so far and I don't know that I am completely comfortable building a weapon from parts that I would have to rely on in a fight. We have access to a wide range of vendors and for the most part they all work as long as they have good testing and are true mil-spec. Almost everyone uses a traditional lower, not an ambi. It's because we keep our trigger finger parallel to the barrel and indexed so we don't want secondary controls in the way. Also it is adding another failure point. All of the rifles that I have shot would be considered over-gassed based on my conversation with you. This is by design as we prefer dependable functionality in very adverse conditions. Because they asked, most of our equipment currently in use started life manufactured by either Colt or FN. There are clearly some guys here who can get more out of the equipment than I can but the rifles are 1 to 1.5 MOA."
