Just mounted the red dot. I went cheap-o and got a red dot at the gun show for $45. It’s by a company called Electro Dot.
I got the lower for $30. I got the pistol kit on sale for $350. So I’m at about $450 if you don’t count the tools I got for this, which weren’t that expensive.
Should make a good car rifle.
Total empty weight is 6-1/4 pounds.
Also this is the video I followed to out the lower together.
