I had. BurrisFastfire III on my 301 in 20 gauge with the Sumtoy mount and it is real low….worked perfect. Fast forward and I bought the new Remington Fieldmaster 20 ga and took the Burris Fastfire Red dot off of my Stevens 301 and put it on the Fieldmaster with a new Sumtoy mount for it. The Fieldmaster is drill and tap so I ordered the mount from Sumtoy for it. Next I ordered a Sightron red dot from Optic Planet for $119 for the 301 and the Sumtoy mount has 4 posts in each corner that I had to file down for it to fit the Sightron sight….really like the sight better than the Burris because of the battery tray easy to replace battery. This is a special that Optic Planet is running. Great red dot.
