Rimfire Training Rigs - RDS or Irons?

[friendlyfireisnt]

Thanks for the input everyone. I think I've decided which route I am going to go. I've been wanting to switch the BUIS on my AR to a fixed BUIS, so I am going to take the MBUS off there, put that on my .22lr, and get a DD fixed BUIS.

I need more practice on irons anyways, so this with my .22 I will get the needed practice. I'll still be practicing with the RDS on my primary AR, and eventually I will throw a cheaper RDS on my .22lr.

Sounds like a good way to go. As someone else said, I also put my 'hand me down' optic on my 15-22. Doesn't 100% replicate the latest and greatest on the main rifle, but so long as it is of a similar type, works great as a trg tool.
