Hello all

Recently purchased the Mod 2 MLOK 14.5 KAC upper SR-15

Would like to change the three prong into something that does both functions, and is not solely a flash hider.

I was thinking of the following options, in order of preference;

1) Precision Armanent EFAB
2) PWS FSC556
3) Whatever else you think I should consider

As a side note, will any of these NEGATIVELY affect the performance of the upper?

Thanks
