Looking for recommendations for a budget red dot. I'm looking for something under $100 and will be mounted on either a Ruger 10/22 or Ruger pc carbine. I put a cheap $20 (off of an airsoft rifle) on my 10/22 and it's a lot of fun but want to get something a little better without spending a lot.

 

I'm gunna go slightly over budget and say get a sig Romeo at 125. Worth every penny for a budget optic. 

Vortex Crossfire Red Dot is typically $110 or so but if you wait and watch it goes under $100 regularly 

I like these for budget rifle red dots.  $40 on sale right now.

Monstrum Tactical makes a decent budget friendly red dot. https://monstrumtactical.com/1x20-ghost-red-dot-sight/

Bushnell Trophy TRS-25 is a solid choice for under $100.  I have them on a couple of my .22 rifles.

I have 4 or 5 of these on multiple guns - great optic.

Check www.palmettoarms.com . . . Some of the Sigs go under $100 regularly.  I tried to go cheap, off of Amazon, for a while but didn't find anything that was worth $20.  The dots aren't bright enough and they don't hold zero very well.

2nd on palmettoarms.com

just bought a Holosun 403 from them 

You mean Palmetto State Armory?

Thank you to all who replied. After some research on your recommendations I decided to go with the Bushnell Trophy that was recommended by Old Glock Guy. Found one gunbroker for $67 shipped.
