Derek45 Posted August 2, 2010 Share Posted August 2, 2010 I had a 10/22 rear sight installed on my Benelli M2 Now she shoots about 12" low at 25 yards. Yikes ! I need a TALLER front sight. I believe the Benelli threads are 3-56 Brownells has several replacement fiber beads, but which one is the tallest? Thanks Link to comment Share on other sites More sharing options...
elynch2007 Posted August 2, 2010 Share Posted August 2, 2010 if it shoots low do you want a taller front sight? Link to comment Share on other sites More sharing options...
Phil G Posted August 2, 2010 Share Posted August 2, 2010 (edited) The general rule is the rear sight is moved in the same direction you wish to move the point of impact. If your shotgun shoots low you need to either raise your rear sight or a shorter front bead. It looks like from the photo that you have some remaining elevation adjustment and can raise the notch in the rear sight. If you raise the notch in the rear sight it will raise the point of impact on the target. If you raise the rear sight to the max and the point of impact is still low, then you need a shorter front bead.

Derek45 Posted August 2, 2010 Author Share Posted August 2, 2010 Opps I meant to say it shoots about 1 foot high with the rear sight in the lowest position. Me no type so good. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted August 2, 2010 Share Posted August 2, 2010 (edited) Derek, I had the same issue. I deepened the notch a bit with a small round file, and made a spacer to go under a HiViz Comp front fiber optic sight. It's .156 high, but, .187 would have been better. Since the HiViz comes with an assortment of screws for the common threads, I used the one for the Benelli to hold the riser to the rib, and the 6-48 to hold the sight to the base. I made the riser out of steel,so I could cold blue it, and used 3M double sided tape for additional mounting stability.

Merlin Orr Posted August 3, 2010 Share Posted August 3, 2010 Benny milled in a front sight - like a pistol sight but with a Big FO - into my rib and replaced the factory style sight. I lowered the POI with slugs to on the money.... Link to comment Share on other sites More sharing options...
Dan Sierpina Posted August 3, 2010 Share Posted August 3, 2010 Derek, This is the sight I'm using. I'll try to get the photos done tonight. http://www.brownells.com/.aspx/pid=26017/Product/COMP_SIGHT Link to comment Share on other sites More sharing options...
Dan Sierpina Posted August 4, 2010 Share Posted August 4, 2010 Here's the riser that I made for the Hi Viz Comp front. It's .156 high, but I think .187 would have been a bit better. Link to comment Share on other sites More sharing options...

I'm sorry for the double post. I've got a new computer and don't have all the old software on it. The photo is too big for the forum to post.

Jadeslade Posted August 4, 2010 Share Posted August 4, 2010 Why do you all think you need a 10/22 sight on the Benelli? Here is the stock Benelli sight on an M1Super90 looking down the channeling on the receiver. This shoots dead on at 50 yds and with hold over out to 100yds. When you cut the rib-you lose some of the rib stiffness and throw your aim off even more. If the barrel does not shoot straight and is warrantied-you can send it to Benelli to be straightened. Or straighten it yourself. Why mutilate a perfectly good gun? With the rib and the fiberoptic bead you have more than enough information to aim.Quickly. It is a clean picture. If you have a parts gun-non-channeled receiver or some combo-you might need something. Link to comment Share on other sites More sharing options...
