usmc1974 Posted February 28, 2012 Share Posted February 28, 2012 I did a search did not find what I was looking for. Maybe a dumb question but, if mag na ported and a ghost ring sight, can it only be shot in open 3 gun class? thanks B Link to comment Share on other sites More sharing options...
outerlimits Posted February 28, 2012 Share Posted February 28, 2012 yep-open...due to the porting. Link to comment Share on other sites More sharing options...
mont1120 Posted February 28, 2012 Share Posted February 28, 2012 I asked the same question a few months back, and yes, poted barrels put you in open. However, my Mossberg barrel did come with porting, but it was far enough back on the barrel that I made some steel .015 shims and covered the open ports using the magazine clamp to hold them in place. Tried using .008 thick ones, but they creased pretty quick. Link to comment Share on other sites More sharing options...
EkuJustice Posted February 28, 2012 Share Posted February 28, 2012 Ghost ring is fine, ports put you in open. I would try ghostrings before you add them. Personally I do better with a bead over any of the other sights. For a shotgun, the porting is highly overrated especially for the loads we use Link to comment Share on other sites More sharing options...

For a shotgun, the porting is highly overrated especially for the loads we use I tried bead only on a Mossberg 930, with slugs, it was around 4" high at 25 yards. I just kept the porting, and stuck on a Primary Arms red dot for good slug accuracy and just shoot open. Link to comment Share on other sites More sharing options...
