I have a Remington 870 express 20 gauge, and bought a Burris Fastfire iii as a red dot sight. I tried the B square saddle mount because I heard it was decent and the weaver style might fit. It did not. Instead I got a picatinny saddle mount, no name brand from China, which I kind of hate. It's got sharp edges, cut myself on recoil, don't like the way it sits. But the big problem is it puts the sight waaaay up high. I'd need a 2"+ cheek riser to get my head up enough.
So... what would you suggest I mount this fastfire to my 870 20 with? The hope is to get it much lower profile.
I've read a little about the 336 mounts here, don't know if that would work for me...? Other good options?
I was originally hoping to do this myself without drilling, thus the saddle mount. But while I really like the red dot, I hate the how high it's mounted, so maybe a trip to the gunsmith is in order...

:agreed: :z-winnersmiley:
Drill and tap it and get a Sumtoy or the 336 you mentioned.
Meadow creek x3. Fantastic mount
I have two 870s in 20 gauge and had both drilled and tapped. Put on half of the Weaver 2-piece base for the 870 and good to go. The base is only a hair longer than the sight and about as low as you can get...
Sumtoy. Send it to him and he'll fix you up

Agreed, his non vented rib mount is one of the best for sure, good guy....
Have you looked at the Burris Speedbead Mount for a Rem 870? Your Fastfire 3 will fit as designed.

I'd opt for this ^^^^^ but if you don't and do decide to go with to drill & tap I'd DEFINITELY go with the Burris 336 base. I did the Weaver mount first and didn't like how high it was, so I got the Burris. But the speed bead system is the lowest you will find.
First picture is the Weaver mount,second is the Burris 336 base.
I tried to upload one of my pictures of my SBE 2 with the speedbead mount but they were too large. Just google the image of what it looks like. Good luck!!!

Based on responses from Burris to questions, I don't believe the 870 speed bead will work with the 20 gauge 870. Has someone here found otherwise?
Curious about this as well.
Meadow Creek mount... It's funny some of you always say drill and tap... Well first you have got to have a gunsmith in most cases to do this for you. So if you don't have a Gunsmith within several miles of where you live drill and tap is not always the option... IMO
Meadow Creek mount if you don't want to drill and tap. I didn't think I would like the forward mounted rib mount. Put one on and I love it.

If you have a drill, get some taps, on the tap package it will tell you what drill bit you need. This only takes 15 minutes, do it yourself. I learned to do this after a local Gunsmith was charging $25 per hole, he went to $40 per hole. Negative Ghostrider!!!! I have done a bunch of guns since then.
Note**** I also recommend buying a "sc=ew checker" from Brownell's, to make sure that you are using the right bit/tap for the screws that you are going to use.

Here is a detailed way to d/t for a do it yourself guy that I found...
I had gone online looking for ways to d/t my 870. I had found the video from 870.com and it was good, but added to what he did. One of the most difficult things to do was to get the center line in top of the receiver.
Clamping the receiver onto a vice makes life much easier, I have jaw pads that are very helpful.
I measured the receiver with a caliper then divided that by half. I set my caliper to that measurement and locked it in with the thumb lock screw.
I then clamped a small flat piece of sheet metal to the receiver, making sure it extended above the top of the receiver.
Using the upper jaws for taking inside measurements I placed one end against the piece of metal and the other side on top of the receiver and marked it. I did this in a few spots on top of the receiver. I then removed the sheet metal and clamped it on the other side of the receiver and confirmed the caliper fell on the same spots on top of the receiver.
As long as the spots fell on the same location, I made a line through them. I then clamped on my scope base and used it as a template, making sure the line on top of the receiver went perfectly thru middle of the holes in the scope base. I traced the holes with a fine pencil. The first hole, measuring from the front end of the receiver should be at .647 inches. (Or at least close to that, whatever you prefer)
With the receiver still in the vice, I used a center punch to help with drilling. Just use the weight of the hammer head. You dont have to hit it hard, I was surprised at how little effort was needed to make an indentation. You can always strike it again.
I then put the receiver in the press vice, lining up the first hole and drilling it with a #31 carbide bit. I used 3in 1 oil for lubrication. You only need a drop or two and it was surprisingly easy to cut through the receiver. Just put enough steady pressure on the hand wheel and allow the bit to do the work. Repeat with the other holes.
After drilling the holes, I then put the # 6-48 plug tap into the drill press. I used the chuck/spindle to tap the holes. Leaving it in the press because it will be lined up perfectly with little chance for tapping it crooked. Unplug the press for safety.
As with the drilling, I held the hand wheel only providing very little but steady pressure and then twisted the chuck manually. One full turn, then keeping the same light pressure, backing out half a turn. Then with the same downward light pressure, twisting and threading more turns, Mabel two or three revolutions and again backing out a revolution, continuing until it is done. You will actually be able to notice the slight movement of the hand wheel. You have to be patient and finesse it a bit, and will be surprised at how easy it is. Repeat the steps until the tap is through the receiver. Once it is through the receiver, slowly back twist the chuck. Again, you will see the hand wheel move slightly. Keep light pressure on the hand wheel until the tap is completely free from the receiver. DO NOT just let go of the hand wheel, it will strip the hole.
I would experiment on a piece of 1/8 bar stock first.
Here are the links for what I bought. Everything worked great. Any more question, feel free to write.
Good luck

I'm another fan and suggest the MeadowCreek mount. Forward on the receiver, about where a rear sight would be located. You get great peripheral vision this way. Also faster target acquisition if you have to mount the gun quickly. Great customer service to with meadowcreek
No doubt drill and tap and get the Sumtoy mount. Great low and sleek mount and the customer service can't be beat.

Amen, you can really look around the sight as a Tom approaches with little or no movement.....
Meadow Creek here as well. I've knock the gun over a couple times and even slipped and fell over backwards on it during a creek crossing and the sight stayed true. That Mississippi clay is slick! Target acquisition is super easy. Didn't think I'd like when I 1st mounted it but I'm a fan now.
