kjshum Posted September 2, 2009 Share Posted September 2, 2009 Hi guys, I've got a Stock in 10mm which shoots really low. To get it to hit the bull at 33ft, I've got the rear sight cranked almost all the way up leaving it held in by only 1-1/2 turns of the screw. Since there isn't a bushing, is there another way of tilting the barrel up? Link to comment Share on other sites More sharing options...
NOSAJ19 Posted September 2, 2009 Share Posted September 2, 2009 Trim the front sight will bring POA/POI up, start filing. This is how I sight-in a fixed rear sighted gun. Cheers, Ando. Link to comment Share on other sites More sharing options...

I wouldn’t, even if you are an experienced shooter, trust anything else than a rest before I start grinding down the front sight. Have you tried different loads? This might have some effect on point of impact too. Link to comment Share on other sites More sharing options...
kjshum Posted September 3, 2009 Author Share Posted September 3, 2009 I've benched it, one hand, two hands, different ammo, different shooter and it is definately shooting low. I've seen a website where the shooter center punched two indentations on the slide at the 8 and 4 o'clock positions below the barrel. I suppose that would work, but I'm looking for a less 'ghetto' solution. ...........Are you sure it is shooting low? It might be a flinch.

Since there isn't a bushing, is there another way of tilting the barrel up? My Match is exactly the same, even with the rear site all the way up, it's still low. I would recommend though that you loctite your elevation screw once you are all the way up. Mine flew away as I imagine it was too far up and came out of its threads. I have yet to be able to get a replacement elevation screw from EAA and now they are saying I have to send the sight in for service. Link to comment Share on other sites More sharing options...
kjshum Posted September 19, 2009 Author Share Posted September 19, 2009 Well I finally fixed the "too low" problem. It seems the chamber surface were the breech contacts wasn't completely perpendiucular. There was a high spot in the 12 o'clock position and resulted in the breech pushing the barrel slightly downward when closed. A few passes of dremmel fixed the spot and instantly the problem was solved! Hi guys,I've got a Stock in 10mm which shoots really low.

Would you mind posting a pic of specifically where you dremeled? With my skills, I'll dremel and my match will then shoot to far left. . . . thanks in advance.

kjshum Posted September 25, 2009 Author Share Posted September 25, 2009 Ground off the high spot at the location circled. Locating high spots is easy, there will be impact spots on both the breech and the chamber face. Also in my case, by pushing in on the muzzle (while action is closed) I could feel main spring pressure. Ie. by pushing on the muzzle, the high spot on the chamber end was actually pushing on the breech and moving the slide minutely back, thus the spring pressure felt. Grinding off a little material at a time, I eventyally managed to get to a point where there was little or no contact. Link to comment Share on other sites More sharing options...
