So, to plays devils advocate here... I only know of two "special forces" individuals first hand. One is my neighbors cousin on the SEAL teams and the other is my wife's best friends brother, who was an Army Ranger sniper. Despite being more proficient than all of us combined, I was surprised in talking with them how little they actually knew about specific brands, even of some of the expensive stuff they used on the daily. I even helped create a parts list for a Mk18 build for my neighbors cousin, so I spent considerable time going back and forth with him on parts, etc. I don't think if I asked either of them which magazines to use, that they would have been able to offer any real advice other than the few brands they were approved to use in combat.That's fair, but he's still going to have a perspective that you probably don't have, and being special forces, pretty much nothing was off the table for them - they didn't get issued Colt M4s - all of their weapons were custom builds, built to what they wanted - all top-shelf stuff, with optics of their choosing, Geissele triggers, Daniel Defense uppers, etc.
On a side note, you might consider removing all of that stuff from your signature block. Pretty much everyone here on the board knows you have a big dick - no need to list all the reasons why.
