MistWolf,
Apologies, I just saw this..............
I exclusively run LMT 5.56 enhanced bolts, the old ones....................
You can cure the *extraction* problems by using the 6.8 enhanced bolt extractor springs listed on the LWRCI website. These are the only compatible springs listed that will work, as LWRCI no longer makes their 5.56 enhanced bolts which were made under license from LMT anyway.
The LWRCI 6.8 extractor springs are a little longer and stiffer than the LMT replacement springs and the LWRCI springs are buffered as they have viton rubber inserts inside them. I use them all the time with no issues, but a little PITA to re-install the extractor pin in the bolt due to more spring pressure.
You may want to also examine the type of roll pin LMT used to secure the ejector. I am sure you know there are 2 types, listed as long and short. ALL of mine came with the short pin which IMHO is a NO-GO.
RARELY, but possible, depending on the install the short pin can interfere with ejector movement and sometimes even lock the ejector to the rear, ask me how I know! Therefore I have replaced all my ejector roll pins with the long ones. Try to get the open part of the roll pin opposite of the bearing surface it comes in contact with on the ejector.
Hope this helps.
