I don't know if anyone has had a similar problem, but here goes:
Last weekend I took my converted SU16B (changed the A sights) to the range. At 25 yards with Federal Match the bullet strikes were touching, but I ran out of windage adjustment with the group still 2 inches to the right of the sight-in target bull. I was using a Burris Compact 4-12X AO in ARMS quick detach ring mounts.
I am exasperated that the Picatinny rail/barrel combo is that much out of square. I guess now my options are to use a red dot with a lot of adjustment amplitude, or to mount the scope with Millett or Redfield adjustable rings.
I had hoped to have some quick-detach capability with this rig; I tried the LaRue mount from my AR but it would not mate with the Kel-Tec Picatinny rail.
I was surprised by the accuracy of the SU-16. It shot as well as my Bushmaster, but I need to face the fact it's a cheap rifle.
Anyone else have optics difficulties with the SU-16?
