AR pistol used as a pseudo SBR in a non-SBR state. This is carried on a concealed pistol permit and is a flat top. It has no BUIS. Currently has a cheap 1" tube red dot on it but looking for something better. Would like some thing with a 4 MOA or smaller dot, and good field of view and is durable enough to withstand banging around getting in an out of a vehicle frequently. Would like to keep the cost below $200 so no Eotech, Aimpoint or ACOG need apply. Open to tried and true suggestions. There are so many dot sights on the market that I am flummoxed trying to sort them all out. And BTW, it has a 11.5" HB and a fixed* carbine buffer tube. It is uber reliable and accurate. *fixed meaning a stock can't be put on it. It can however be fired from the shoulder with just the tube if needed. This is what I am talking about. It has a different tube and sight than in this old photo.
