Some people only care about the “fit” and “feel” and “tightness” of their rifle.
I care about those three things…but it has nothing to do with a rifle. 
Use them if you want to but I get tired of having to put bits and pieces out of a lower when someone brings me a rifle and says “it no work no mo.”
None taken, thanks for the tip and Merry Christmas.
This is how God intended.

They serve NO PURPOSE in a fighting weapon.
The main reason for this is because they can come apart and become lodged in the FCG.
This is a NO GO.

Ok, I can buy this reasoning. My Noveske upper fits tight on my RR Colt lower, but my 6933 rattles like tin cans in a bag on it. For those of us who are obsessive compulsive and anal about immaterial matters such as this, is there a viable solution?
if you just really, really have to have snugness, an o-ring around the takedown lug will accomplish it. but somebody had a counter for that, as well… cant remember what it was, but apparently that caused a problem for someone once too.
With the gun slung up right, tucked up in a good carbine shooting stance, you won’t notice any rattle. If you do, you’re not concentrating on the right things: you’re doing it wrong. Shoot the gun more, fingerbang it less.
Well said:D My first AR came with the little wedge things, they did come out and cause me some hassle. I trashed what was left of them and never had another problem.
My first suggestion would be to get over your issues and understand that it is a combat gun and not a bolt gun.
If that does not work, send the upper to an FFL dealer for them to match fit your upper to a new lower.

Better yet he should just send the whole weapon to me. I dont mind some rattle:D
While I appreciate the replies, I fully understand that it’s a form not function issue. I have no issue with those that appreciate function to the exclusion of all else. I just think it would be a nice touch that a $15K setup have a little of both.
As I don’t have a spare 5 figures laying around to try another Registered Colt reciever, I’ll suffer the rattle. This isn’t a safe queen that I “fingerbang”, but a rig I compete with and train with. It isn’t likely that I’ll need it to save my life or the lives of others, but it’s the reason I shoot.
In a previous life we considered rattles to be bad juju. They were routinely corrected with riggers tape. Sorry if I offended anyone’s sensibilities with my dislike of them. :rolleyes:
I think all of our sensibilites are intact.
