In its current configuration I have zero muzzle flash, it seems to do quite well accuracy wise out to 200m havent had an oppertunity for longer shots yet, I know the lack of flash would be ideal for non detection but I am wondering if its doing it for the right reason or am I sacrificing performance somewhere or what (thanks for any positive feedback) My partners 11.5" with 5.5 suppressor belches a fireball 3foot by 1 foot dia every shot I cant help but laugh its like the scene out of predator I just wonder why the extra 5 inches makes such an enormous difference

Whatever works.

Zero muzzle flash?  Even less than a Vortex?  Curious...

Shorter the barrel.. the less time the powder has to burn.. most rounds are designed for a 20" barrel so..

Longer barrel means more of the powder has burnt off before the bullet leaves the barrel.
