Ion: NDZ Feedneck, Halo w/Rip, Power Scepter Kit, Planet Eclipse QEV, Evolve Pi Regulator w/Timmy gauge, check it unimount, FBM trigger, AA 68/45
Light, Adjustable, No Magnets, Durable, Smooth, Little Side to Side Movement, Look in my opinion
Allen Slot was Metric.....Not sure
I got the trigger about two weeks ago and so far so good. I like most people have a hard time being able to walk the stock trigger even after adjustments. Also I'm not particularly a fan of the magnets I just dont like the feel.
The trigger, however small and upgrade it is, it can help a lot. Its very easy to walk especially after you adjust for your own liking. The pull is very short and smooth and is easy to walk even for the novices. My brother who has never played before had no problem keeping it going on rebound. There is hardly even side to side movement and can be walked from different angles.
The only problem i found was that mine for some reason when i adjusted worked best with metric allen wrenches, that might be a plus though if thats what you got?
As far as the looks go i think it looks great and not a lot of people have it, at least not around here and everyone seems to like it.
In conclusion, I would definetly recommend this trigger for people of all ages and experience, its a cheap yet important upgrade and for the price of less then $25 its a steal. Hope this helped, enjoy!
