Guys,
Well, I recently upgraded my OEM Colt 6920 "H" buffer, to one of Grant's "H2" buffers, which I had read (all over this forum), that the H2 buffer is a good upgrade to do on a 6920.
SO, I have not shot too many shots at all with it, and I decided to go out today and put some rounds through the gun. I had previously shot with the H2 buffer, probably 100 shots or so, with no problems.
SO, today, I started having problems with the bolt holding itself open on the last shot. EVERY time, I was dry firing on the last round, as I didn't know the mag was empty, and the bolt was not holding open.
SO, most of this afternoon, I had just been thinking that I had too much Slip2000 lube inside the chamber area, so I THOUGHT that the excess lube MIGHT have been the cause of the bolt slipping over the mag, and not holding open... (not sure if excess lube could even possibly be the culprit, but that was my only guess).
Just a note, this 6920 is very new. It's only got 400 shots through it, and has never had a single issue, malf, FTF, or FTE.
SO, tonight, I was just now cruising around on the net, and I came across this description for a PRI gas tube, which makes mention that a common symptom of being "over buffered" is the bolt not holding open on the last shot...

Now THIS has me thinking, and I'm wondering if I am "Over-Buffered"?????
Thanks for any help guys...
