I want a monolithic upper rifle. I like the look and being able to mount an optic anywhere. Which one do you have and why?

I have a Vltor vis 2a (10 inch) on a 16 inch rifle, as well as the Mega mono rail mid length on a 12.5 inch rifle.
The vis is a quad rail, the mega mono has a full length top rail and you can add various sized rails where you want them.
Both are very nice. If I could only pick one it would be the Mega mono.
I have small/medium sized hands the Mega mono due to the fact it is "tubular" fits my hands better and feels better than having quad rails.
Do you have pics of the Mega rifle? My next build will be an SBR and I want as much handguard as possible w/o blocking use of a can. The Mega mono uppers don't list handguard lengths on the web and after seeing the thread about 11" handguards being too close to 11.5" bbls... I am trying to see the Mega Mono uppers with bbls in the 11.5 to 12.5 range.
Thanks!

Don't limit yourself to proprietary barrels.
Vltor VIS is the gold standard.
While opinions will vary, which ever one you chose I am sure you will be happy with and no one will give you a hard time for it.
Vltor and Mega are my two favorites. I own the Mega Mono. I went with that one over the vis because there are fewer parts. The vis has actually two parts. The bottom drops from the top. This allows you to attach a grenade launcher to it. Visit their site for a visual demonstration. While this is cool, I will unfortunately never own a true 40mm launcher, so I could care less about that feature. The Mega is a true monolithic upper, just one piece. There are some tech differences too, but I don't think it will matter much. The machining on the Mega is perfect the thing is like art work! Also, the Mega has a deep black finish the Vltor has kind of a gray tint to it. Ive the vltor in person, it just didn't impress me as much. Just my opinion of course.
The MRP is fine if you are ok with paying the price for MRP barrels, and whatever few aftermarket barrels there are out there (also pricey). The MRP also allows you to change barrels pretty quickly but then you need to know the zero for each barrel if you want to keep the same optic or have a different optic for each barrel.
The other mono uppers allow standard AR barrels but are not quick change. You have a lot more options.
Ditto on the Mega Mono. Beautiful craftsmanship.
One consideration - the VIS receiver is machined from a 6016 forging while the rail section is made from a 6063 extrusion. This Vltor Rep who provided this info also said the VIS was manufactured in this way "because you cannot weld 7075."
To El Cid - The useable rail length on a mid-length Mega Monolithic Quad-Rail Upper is 14.75", and that on their rifle-length is 3.37" longer, or 18.12". Also, the side-to-side rail width is 2.09".
