Thanks BarnBWT appreciate the comment
The Flash Hider does help a lot in groupings, I have gotten 1.7 - 1.5 average groups with it. Ive already updated the firing pin to the 2 piece pin and keept the original as spare. Changed out the weak firing pin spring and that made a nice difference.
I finally locate the actual flash hider most commonly found the the Vennie model FN49 so I plan on changing it over to that one when it comes in and see what groups I get on it and if it makes a difference.
LOL, sure does help on the noise some that I will say.....
