[1/8" (3.2 cm)] I purchased 5 years ago for turkey Hunting and it has worked great

[0.055 lb] Bought SpeedBead quite awhile ago and through sporting goods manager he sold me the #30041for a Benelli M2,etc.Remember there is no listing for my 20ga SuperSport so I gave it a try and worked like a charm.There is a little part of the mounting bracket that extends out from the stock and action.Its so little its not worth trimming or doing anything.Happy!I would recommend camphor the hole on the bracket so roll pin goes through and doesn't stick on assembly.

[1/8" (3.2 cm)] Mounted on my Beretta A400 Xtreme Plus. Works great.

[1/8" (3.2 cm)] Increase my hit ratio by 70% or more! I’m amazed by this thing strong construction and works great. I struggled with shooting with both eyes open but with this it just feels natural

[1/8" (3.2 cm)] Have had many different top brands of optics on my competition rifles. Burris is the clearest and most well made

[1/8" (3.2 cm)] I have a Benelli M2 which is not tapped for a scope. I read the previous reviews on the SpeedBead, but decided to give this a try anyway. So far, for my M2, this is a solid mount for the FF3. This mount just replaces the shim between the receiver and the stock. The shim has dowels that press tightly into both the receiver and the stock at the top and the bottom. They were tight going in, but pressed in nicely when I tightened down the bolt for the stock. Once in place, there is no difference between how the SpeedBead and the original shim fit between the receiver and the stock. The mount is tight against the receiver to the front of the mount and the stock to the rear. The SpeedBead & FF3 came w/additional mounting plates to adjust the height of the FF3. I did not need to add any additional height to mine though, the sight falls right in line w/my sight nicely. This package also came w/two sets of screws of different lengths, for use when adjusting the height. It also came w/the battery. And, it includes a protective/sun cover. The FF3 is easy to turn and adjust the red dot brightness and it automatically turns off after a period of time. As I use this system more, I will update my review to reflect my experience w/the SpeedBead mount and FF3 red dot sight.

[0.055 lb] Works really well but after shooting a little, it needs to be sighted in again. Helpful hints?

[0.055 lb] Easy mount to the 870. Worked perfectly until I broke the lens, no fault of Burris just abuse. Burris replaced it, no questions asked.

[0.055 lb] I purchased a Benelli M1 back in 1989. Thirty years later my vision isn't what it used to be so my ability to pick up that front sight, especially in poor light conditions has diminished somewhat. Also, the M1 has very limited options for aftermarket optics. I purchased the Speed Bead specifically for for the Benelli. It installed easily and precisely. The Burris Fast Fire 3 mounted up in minutes. Sighting in was a breeze. This is a dynamite product and a great combo. Your tactical shooting pace and accuracy will improve even if you already are a highly competent marksman.

[1/8" (3.2 cm)] I have had a Speedbead for about 7 years now. Works perfectly on my 1100, 11-87, and my 870. Soooo much better than the old Weaver Qwik-Point from years ago. Ran a straight at Skeet the first time I took it out. Thank you for making excellent products.
