Just got one for a Mini Recce build. While it does have a crisp break, it just feels a lot heavier then the advertised 4.5lb. Took it off and put on SD3G I had on another build to get me by this weekend. Just ordered up a SSAE blem for 130 bucks.
Every time I have gone away from a Geissele it has always bit me in the ass. Got a TT Diamond AR trigger, to see if it was comparable to a Geissele NM. Hated it and trigger shoe was too sharp around the edges. First stage almost felt that it had no preload. Didn't have 500 rounds through it and the disconnector broke. A lot of hassling with TT and they finally sent me a new trigger. Now, after reading and hearing people praise the MBT, thought I would give it a try. I hate it.
