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.
Here ya go young fella,,I just asked the same question awhile back !!!! I will be getting/building one in the next few months !!! Lots of good info,,read it all & you Will Believe !!!! :D

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.

why not!
FYI.....MRPs will now except ANY barrel that any other AR15 would accept. That said...every MRP barrel in the lineup has fantastic accuracy and besides a krieger, Rock SS MRP barrels are the finest and most accurate barrel Ive seen or used and charted on paper in terms of an 5.56 AR, I am not looking to use any other barrel besides the MRP proprietary ones.... There is a reason they cost so much. They have no competitors and MRPs are a complete system and not a neat little upper thingy.
Vis is POLYLITHIC.....nuff said, not knocking but clearly its not a monolithic rail.
I will choose not to commit on the mega stuff but they need to at least put some t marks on the rails.
Don't worry he won't...he will have the best of both worlds with any AR barrel he wants as well as the full MRP lineup...not to mention he will have a true monolithic weapon system rather than a polylithic upper...and can hit barrel changes in under two minutes....how fast does the throw away barrel remover thingy on the vis take?
I'm loving mine, going today to zero the second one:cool:
Concerning the zero, you will be amazed on the return to zero. My first test was with PMC ball, took off the optics(T1 combo w/Larue mount/NF w/ Larue) and removed/installed barrel and I was within an inch at 100.
I will do a more thorough test in the future and after speaking with LMT, I was told it's usually less than that!
I'm waiting on my 6.8 barrel/bolt-any day!
I wish I had picked up these earlier--

If I was doing a build, i would likely go with the Mega do to its flexibility in terms of rail location. I have a LMT and love it but there are times when I would like to have a little less real estate in terms of rail.
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!

I'm sure you will be happy no matter which one you choose. I went with a midlength VIS. I decided on it because it would work with the older style PWS system, didn't require a proprietary barrel, and looked and sounded like it would hold up to abuse well. I have been very happy with it and am thinking about another one for a 6.8 build.
Hi pal, the info is coming from a gent on tos with a thread over there about it.....

Marks kit really is one of the finer examples of what I am talking about in reference to a system, and just assume he already has his new 6.8 gear pic'd. I watched Mark do a ton of research before investing as heavily and nicely as he did in the mrp system. The MRP is not for a person that does not want to push envelopes and innovate the AR platform and rather just wants a single, nice shooting rifle. The MRP is for diehards imho and not the route to go if you are not going commit yourself to it as it demands quite a penny and more importantly the willingness to actually push the performance and capabilities of it through all the various options it has.
Now that folks do not have the whole proprietary barrel non issue to spout on....and with plenty of hard data to support the amazing lack of poi shift done by others along with myself, I think the "MRP bent rail syndrome" is the last knock on the system.

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".
