It does everything it says it does. Ive noticed a good effenciy difrence. Ive noticed people giving this a bad review because it dosnt fix their first shot drop off. Well no where does it say it will help it at all. It says it allows u to dry fire and improves you effenciy. Then only product that is advertised ot improve FSDO is the Slick Shot ram.
It was a little pain to install because i dont think the instructions had enough detail in them.
A well made product. Duffently buy this or a tape worm for your gun because they do the same thing.
Well, if you dick with your dwell it will change the FSDO, or if u get the blackheart board, or an LPR all of those will considerable help reduce that, so will the RIP valve from ND. but the blackheart will completely take the FSDO away with a new setting it has.
