Remington 870 express turkey camo 20 GA 21'' barrel question

[Oreegun]

Looking for info and thoughts about the gun specifically a mid sight bead.  The gun does not come with one.  I put a TruGlo starbright sight on the front.  Do I need to get a mid bead put on it?  If so what size?  I had Williams Slugger sights and took them off.  I just want the glow bead sight.  Any help and insights are greatly appreciated.

I have an 870 21" 20ga youth and had a local gunsmith add a mid bead. Not sure the size but I do know it's the same size as the one on my 21" 870 12ga.  For me the mid bead is a must.

Don't really need a mid bead. Just make sure to stay down on your stock and look in line with the rib, not down on it. Hope that makes sense. I put a vortex sight on mine and a sureshot stock.

Thanks for the replies It makes sense bearing down on the stock and a visual sight plane with the vented rib.  I'll probably check it out on some paper and decide if its necessary to put a mid bead on it.  Appreciate the responses.
