    Ok stupid question here, but what exactly makes a rifle monlithic? Because it looks like these monlithic ARs are still two peice designs, so whats the differance? I havent got to handle one yet so just trying to fugure if its worth it. Whats the benefits, and is it just an answer to question not needing asked.

    I could be wrong but, I think, that term is describing the physical 'size' of the gun. Maybe like 'intimidating looking.'

    it means the top rail from above the charging handle to the fsb is one piece

    The upper receiver and the quad rail or tube are machined as 1 piece.

    The only real benefit I've heard of is for mounting optics. You can read up on the Areo Precision Continuous Optics Platform...all it is, is a monolithic upper.

    ok cool, so the upper and the hanguard are one peice. Makes sense, and I now do not feel I am missing anything. Thank you for the info

    Also makes free float rails that aren't part of the reciever more stable as its basiaclly an extra attach point to the upper. Looks cooler too...

    Never Forget.

    What makes free float rails more stable?

    I'm no expert with monolithic uppers and this is my opinion: From what I've seen, a conventional free floating handguard is threaded onto the barrel nut. With the monolithic uppers, the upper receiver and the handguard/rails are machined as one piece, with it still resembling and functioning as a free floating handguard. Since everything is machined as one piece, with no additional attachment points, it makes the assembly more stable.

    I understand that but 1stMarine said, "Also makes free float rails that aren't part of the reciever more stable as its basiaclly an extra attach point to the upper. Looks cooler too..."

    If it's a mono upper how can the rail be seperate from the receiver? Kinda defeats the idea of mono. Correct?

    I'm thinking I must be misreading it as well.

    I meant that in reference to the mk12 spr mod 0 upper, how it has a built in riser that attaches to the top rail of any ar, then threads onto the barrel nut of the reciever. Not about one that was machined as part of the upper.

    Never Forget.

    Another nice part of the mono upper is the ones I have seen have a barrel nut included in the assembly that is more of a spanner nut and does not have to be aligned with the gas tube because it stays closer to the profile of the barrel.
