Can someone with a caliper tell me what the od is at the end of the barrel on the polymer barrels? I would like to make some muzzle brakes for them.

Matt,

My Big Cat measures 15.5 mm diameter and 30mm long

30mm long? Is that the brake your using? 15.5 is the od of the barrel.

Matt,

Sorry.  On the Gamos they have fluted polymer barrel sleeves.  The flutes start about 30 mm from the tip.  Meaning the first 30 mm is a full 15.5 OD.  Thought that might be helpful as you design the internal stops of your LDCs.

Matt,
Did my email with the Big Cat measurements never arrive?

Am on the road right now, so I can't remeasure it..
