View Full Version : Question about WOA spr barrel and JP Muzzle Brake

Which size muzzle comp would I need to fit nicely onto a WOA spr barrel?

The two sizes of the comps are .75" OD and .875" OD. I can't find anywhere if this dimension is for where the comp attaches, or for the main part of the comp that's a little bigger in OD.

OD on the WOA spr barrel is .73"

Here is the link to the comps, I'm talking about the 1st, and 5th one listed:

You want the .750". The larger size is for bull barrels.

JP brake carboned up the crown of my barrel so bad my gun was shooting like a shotgun. Good luck with that part.

Thanks for the input guys. Shortly after I created this thread, I decided to go with the PWS FCS556 :rolleyes: I'm so indecisive

Why not go w/ the Battle Comp ? The manufacturer has photo's of them on SPR's on their FB. Just an idea...
