Saw a 6.8 M42K on a 16" 5.56 barrel and it produced quite a bit of muzzle flash. I was very supprised. How much flash are you guys getting with your 5.56 M42Ks? What barrel length/ammo are you using?

I have an AAC Ranger on my 11.5" upper and I get zero muzzle flash that I can tell. I am shooting cheap Remington UMC 55gr.

Perhaps it was because its slightly overbored for the 6.8?


I was wondering this (is it because its overbored?) but I never noticed the flash till it turned night. Then it was VERY clear there was a baseball sized comet shaped flash coming from the end of the can once it was really dark. It would be reduced to the level of the Phantom flash hiders light after the oxygen was extinguished but if you waited a few seonds it would flash big again for 2-3 rounds untill the oxygen filled the can again when youd stop firing (4-8 seconds of no shooting) then youd get the big flashes again.

Have you shot your suppressor at night with no lights around?

The 6.8 is bored out to .370, so when shooting a .224 sized projectile down the tube, I could see why there would be muzzle flash as the 5.56 can is bored out to .320. There probably wouldn't be any flash from the 7.62 SD with 5.56 because of how frickin long it is.

I shot it at night in an enclosed space - no flash to speak of at all from my perspective as the shooter. Didnt have anyone else around to check it from the sides. I was shooting Fed xm193.
