New site, shoots high

[Kiwibru]

Finally had my A0M130 in the shop to have the flip site removed and a new MC003AS adjustable rear site installed in it's place. At 75 yd. the rifle shoots high 4-8". I have the rear site peep slid all the way forward. Besides having to compensate via my eyes through the site...a drag...what can I do ?

If your down as far as you can go on the back, the only option is to build up the front. New taller front or modify existing if possible.
Sounds to far off to try to compensate with different ammo to me.
