I have been shooting both Geissele SSA's and a RRA National Match trigger. I saw the LaRue MBT mentioned in another thread and for $80, why not? Just installed it in my CMP match legal AR-bomination. Agree or disagree, here's my take on these three triggers. This is my AR-bomination that's so fugly, not even its creator likes it-
I have since installed a pinned M4 butt stock, so now it's even fuglier. Above group at 100 yards via irons in super cold weather. I think I was actually using Marvel Mystery Oil as a lube because other lubes get gummy as temps approach zero.
This particular AR is under 7.5 lbs per CMP (stupid) rules, so IMHO better triggers are more evident in my rapid and offhand stages. I've shot it in competition several times with the Geissele and twice recently with the RRA. Going back to late last year, I have a string of 3 maybe 4 wins with the Geissele in this AR at two different match locations plus a silver at Camp Ethan Allen. The last two matches I shot OK, but in both cases dropped too many points in rapid and offhand. Bad shooting or difference between the triggers? At the same match last Sunday I got the win in the Garand match yet lost with the AR+RRA, though not by many points.
The RRA NM is a very good trigger, but it's no Geissele SSA. My scores are definitely down a few points with the RRA, not drastically, but consistently. The break is not as clean as the SSA nor is the break as consistent. Also the RRA feels like the 2nd stage break takes more effort vs. the Geissele that is more balanced between 1st and 2nd stage effort. Is the SSA worth more than twice as much as the under $100 RRA NM? That's debatable and I really like the RRA NM for the money. Unless you are investing a lot of money and time plus achieving competitive scores, I'd hesitate to recommend spending the dough on the Geissele. My other SSA is actually a SSA-E and in my sub-MOA 6.5 Creedmoor AR build, which was a budget build except for the trigger, barrel, bolt, and scope.
So how does the LaRue MBT compare? I'd rank it between the RRA NM and the Geissele SSA. Break is cleaner and crisper than the RRA and pull is more balanced than the RRA. There is the slightest amount of creep in the MBT break, but unless comparing directly to the Geissele it might not be noticed. There is a very small amount of play side to side for the MBT trigger vs. zero from the SSA. Given its pricing is even lower than the RRA NM, the LaRue MBT is a no-brainer. Next time I need a very good trigger, I'll get another. I do think the Geisseles are better by a decent margin, but I doubt I'll buy another because of the price and I can swap one of the two I have into something else if necessary. Of the three, the LaRue is certainly the best value.
Just my 2 cents, yours may vary. I'm going to leave the LaRue in the AR-bomination and see how I score next season.
