I received my Warbird protector mount for my Burris FF3 a few weeks ago. I absolutely love the mount but I did not like how it covered the 4 posts that help secure the sight to the base. Basically the only thing holding the fastfire and protector to the base is 2 screws instead of 6 points of contact.
What I did was build up the 4 posts with JB Weld and filed them to fit the FF3. Those 4 posts are extremely strong and will add some extra insurance from getting bumped.
Also just got my trigger back from the gunsmith and it's a perfect 3.5 pounds! Making dedicated turkey guns is fun.
