And made a barrel band/sight out of micarta to get the height right. You're right - does surprisingly well. Great little trainer with a removable rotary magazine and shells to put the pellets in.

sufficient upper body strength causing them to lean back in an effort to support the weight. Generality, of course, and I try to correct it through lighter arms, exercise, repetition and/or alternate positions. Sometimes the correction just has to wait until there has been enough practice.
