What size riser (shortest one preferably) would I need to purchase to clear the front sight on my M4 so that it doesn't show up in my sight picture?

You don't need one. I have a flat top AR with standard front sight and I put this site on and had no issues at all.

I have a front sight on mine also and didn't have to add any risers. I mounted and started shooting right away with no front sight in the way

Without a riser, the front sight is visible, but not a distraction. However, I don't mind it, with a rear buis you can cowitness pretty well, and almost zero the dot with your irons.

You will need a riser. I found one at Academy for about $30.00. Works great and scope is very accurate.

Should be high enough with this riser. It put my scope up enough to see over my AR15 front sight. It is strong but lite and easy to put on and off.

No, you will need a riser. I bought the NcStar AR15 Weaver 3/4-Inch Riser (MARF) from Amazon for $11.99. Works great.

It doesn't have the same height as the front sight on my standard mil-spec flat top ar15 front sight. I bought this based on these answers saying it was the correct height but it isn't high enough without buying a 1/2" riser

It all depends on your front site. I did not want to remove it so I needed a higher riser to see over it.

Probably. I put mine on a M&P; 15-22. I used a 1/2" riser as well to clear the factory sights.

Yes, it is a see through one inch riser. I purchased this for my sons H&k; g36c airsoft. They use goggles for protection and nedded the extra clearance for mounting holographic sight. It's very sturdy yet lightened by holes on sides.tightens well and stays in place. On his H&K; g36c he was able to still use iron sights by see through riser cavity. I would purchase again if the need arises. I've researched and couldn't find anything better for the price and purpose.

This is to help other Ruger AR556 owners. I apologize posting in this thread. 1" riser did not work for me. It's too high. I'm going to try 0.83 next.

I had a bolt-on muzzle brake on mine. It clears just like a factory front sight. I noticed no change in the height of the front sight.

It will probably be too tall. I love the riser though. I needed to get my scope off the upper rail just high enough to be able to put the scope protective caps on. Works like a champ and brings it up to eye level for me. Maybe consider ditching the iron sights you have now and switch to magpuls offset sights. Little pricy but that's what I did. Hope this helps good luck.

Yes. The riser is just that a riser. You still obviously need a method to attach the scope to the riser. I used a 3/4 riser and medium height Weaver rings. How high you want your scope is something you'll have to decide. Hope this helps.

Yes. You would have to purchase a low rise mount on here but it wouldn't be expensive.I honestly don't see you needing to change it! When you use the proper stance and have the correct cheek weld it should be perfect, this is a standard red dot height. Don't bend your neck and bring your eye to the sight, bring the gun and sight to your eye!

Not adjustable to the extent you need it. I would look for a different height sight or you can get a profile riser mount (UTG sells one for about 8 bucks, and you can get them in different heights). Hope this helps -

It depends on how high up your red dot optic is above the rail. You can easily get a riser rail for a few bucks if it doesn't.

It should view over the front sight post no problem. I may not be 100% positive, however in my experience I have never seen a m4 platform rifle in which this sight could not see over the front sight post.
