Setting up my 20 ga for my 10 y/o nephew to use this spring. Need a red dot. It's only going to be there for 4 weeks a year tops because this is not a dedicated turkey rig. It's what I carry when running the squirrel dogs so it has to come off before the season opens. Since its time is going to be short lived, I'd like to keep the price below $100. The cheaper the better. Thanks in advance.
