6-48 is standard and all I ever use unless one is stripped and needs to be bumped up to 8-40
When I need expert advice I tend to talk to myself The older I get the better I used to be

7x57 I'd look into calling William at Sumtoy and ordering one of his mounts. Just tell him what gun you've got and what red dot you're going to mount on it and for $50 he'll send you a mount that's rounded out on the bottom to fit your guns receiver. The two of his I've used have fit the contour of my receivers like a glove and both sit very low. This thread has some info and pictures of the Sumtoy mount http://www.aldeer.com/forum/ubbthreads.php?ubb=showflat&Number=3613736Good luck with whichever route you take! Post a pic of whatever you end up doing

Against my better judgment, I tried a Sumtoy mount recently. I can’t stand that thing. I had much rather have the Burris mount that all my other shotguns have. The Sumtoy seems to sit up higher than the Burris mount, as well.

N2 that Burris does sit lower. I found this pic earlier. Burris 336 on top Sumtoy middle picatinny bottom The Burris mount may sit a little lower, but with the Sumtoy mount being contoured and the Burris mount being flat, the Sumtoy isn't as high as it looks in the pic. Either is better than mounting it to a rail. The Sumtoy was a good bit higher when I compared mine side by side.

This Scalarworks mount with a RMR sits very low. D&T and Cerakote on mount was down by Inverness Outdoors I don’t like the looks of a rail. Do they offer it the same size as the red dot footprint? I used Inverness Outdoors for a recent dip job.

I used Inverness Outdoors for a recent dip job. The Scalarwotks is only compatible with Trijion RMR; the mount actually replaces the baseplate of the RMR so it can sit as low as possible. Not cheap; but a clean setup.

Half the reason to put a red dot on is you don't have to get your head as low on the stock. Also, clamp on rails are like $20. Not to me it isn't. I want the dot mounted low for the same reason I want my scope mounted low on a rifle. I want the dot to be where I'm looking when I throw the gun up. It feels natural for me to have a good cheak weld on the stock. You can't have that with the dot mounted high.

I use whatever is provided with the base I am using. Most of the time that is a 6-48 unless the Burris 336 base is used which comes with 8-40 screws. Sumtoy mounts are hit or miss on screws sizes. I've seen them come with both size screws so I never drill holes until I have the base in hand. 6-48 allows room to fix threads if they strip also
if you have a base with no screws, screw length will depend on the base and the gun. A 1/4" should work with 95% of applications though ... at least with a little trimming

Well I finally had a night not studying for exams or clinic procedures so I D&T'd my 870. I'm very pleased with how it turned out. Hardest part was squaring everything up on the drill press, then locking that in place, then triple checking everything. Mount is a Sumtoy. Told them what I wanted and they said can do easy (great dealing with them--no affiliation). I'm really happy how solid the whole setup is, and I'm glad I went with the 8-40 instead of 6-48. I put the base as far to the rear as I could before it started to gap. Plenty of adjustment left on elevation. Bore sighted it with laser and hopefully can get it on paper this morning. The only thing I'd change is screw length. I have more threads that I can engage, so I might do that at a later dated, but would most likely need to dress them down. Thanks for all the guidance--you know who you guys are. For future reference 8-40 NS screws required #28 drill bit 8-40 screws torqued to 12 in-lbs with blue loctite

Titanium cerakote on the metal? I’m gonna try an RD on at least one gun again, as the OS setup it has don’t have quite enough elevation adjustment without more parts/work. It’ll just be an RD that hasn’t let me down on other stuff. Equipment messing up a gimme on a bird is hugely frustrating. The nut behind the trigger is always a known issue. FWIW: I’ve always ‘believed’ the 870 20ga receiver was too thin at the rear for good tap/screw depth? If not, and someone would make a solid mount for the curve/drop at the rear, you could likely get a dot very low to the rib/receiver. Right now, if I decide to RD my 870 20, it’ll probably get a rib mount. OTOH, my turkey guns are turkey guns ONLY, and my eye just needs to be where it needs to be to kill turkeys….not shoot quail. It doesn’t matter if that’s down on the rib or using a lower cheek weld to get behind a dot or sights that sit higher. It’s rifle shooting, not shotgunning.

There is plenty of meat at the rear of a 20 ga 870 receiver. The problem is when using a factory 4 screw base and the holes that are roughly forward of the ejection port. There's a shoulder in there the barrel extension butts againts and the receiver is really thin there.

What color is your metal, titanium? The color, I believe, is called "patriot brown" but it's more green than brown in my opinion.
