What you are talking about is a linear muzzle device. Don't expect much in the way of recoil reduction but they do lower the blast/noise behind the barrel.
There are cheaper options than the Claymore. JAL and Black River Tactical make dedicated 6.5mm linears. PWS makes a pricey 30cal at $150 but it looks like some thought has gone into it. All 5/8*24 thread only.
There won't be any noticeable difference in rearward sound between a 30cal and a dedicated 6.5 muzzle port. It's all about eliminating ports that point anywhere other than forward.
