Back to the post. There is no reason to shorten the barrel unless that is what you want to do. Porting can add anywhere from 0 to 2 or 3 inches to your barrel. If you want to keep the same barrel length and do not want to shorten your barrel to add a break then have the current barrel Mag-na-ported. That will not change the length at all, and still allow you to port your barrel.

Personally I do not have a problem with porting barrels. Some do-I do not. I like them on most of my rifles. For me the extra noise is better than the muzzle flip of a non-ported rifle. I do it more for control of muzzle flip, and less for recoil reduction. However to each his own. Tom.
