Hello guys.
I need some help. I want to put a quad rail on my OR model. I have been reading all kinds of things about this and I am more confused. I don't want anything expensive. I just would like some rails to mount stuff on ;) So I have been reading that some quad rails might mean that I have to change the gas block, and then some are free float and some aren't. I would like to do this myself and keep things simple. I would like to mount a light and a foregrip up there. I don't put a lot of rounds through the gun. I mostly shoot the 15-22. Anyway can I just get a drop in quad rail that will just fit or do I have to go through a bunch of stuff to do this on the OR model? Thanks in advance.

It really depends on what you want to do. There are some drop ins that would simply replace the handguard that you currently have. Not sure how good they would look with the railed gas block, but that would be personal preference.

You could also replace the gas block with a smaller one, and then get a longer rail that would go over the gas block and lengthen your sight radius. These would be the free float variety and more difficult for you to install.

If all you want is a light and foregrip, you can get pieces of rail that would attach to the handguard you already have also. Or, you could get a Magpul handguard and add pieces of rails to attach some accessories as well.

Just depends on what you want and how much money and effort you want to put into it.
 
I have a UTG quad rail on mine now and have had 2 others in the past. I highly recommend them for what you want. They are made in USA and seem to be very high quality. They run about $55 or less on amazon and for the price can't be beat. I tried 3 other brands before finding this one. I wouldn't use anything else now. Attaches easily and matches my mp15 perfectly.
 
...what Andyems said. For what you described, you want to get a rail that will be a two piece, drop in rail. Same length (Carbine Length) that you have now. Going any longer or going free float will require a little more work and removal of the gas block, delta ring, springs and such. With the rail recommended above (find a UTG Pro), all you have to do is pull your delta ring back, pop your hand guard off and snap in the new rail just like you would your existing hand guard. Should take all of 4 minutes.
 
The UTG Pro is a very nice rail and is easy to install. It is heavy though. I prefer the Magpul version that you mount rails on. It is very light and sturdy and you add just what you want. HOWEVER, Grover may accuse you of having an air-soft rifle.:p Neither of these should take more than 5 minutes to install and neither will interfer with your gas block.

omega tactical's drop in quad rail is inexpensive and hella solid and for 30 ducets, it opens up room in your budget for other goodies :D

heres the link to amazon

Hey I quit accusing people of that, now that both of mine resemble airsoft rifles, those kids trick them out way beyond what we do anyways. LOL :)
I would recommend the Omega Tactical, the UTG pro or whatever floats your boat. Even the magpul with rails on it is nice, I dont really have much for rails on mine, I kinda find them uncomfortable to hang on to.
 
My OR came with a quad rail, changed to a MOE hanguard and never looked back. I actually have the orginal in a box still.
 
Thanks for the info guys. So basically I can add any drop in rail that is carbine length on my OR without modifications. I like the idea of the MOE with rails added where needed from the weight perspective, but I don't like the looks of the MOE. Someone above mentioned that I might be able to add rails to the factory hand guard that came with the OR. Is that possible? How would that mount and where would I find that? That might satisfy my needs.

I am looking for the same deal, a rail to mount under the original hand guard.

I've tried a 9 slotted Magpul picatinny rail section. The holes do line up but it needs longer screws to make it work. Or some kind of modification to the heat shield on the bottom section o the hand guard. I'm still trying to figure how I want to do it.

Here are a couple I found....I have never used these, so I can't recommend them or offer any advise on them, other than that they are available.

ProMag Handguard Carbine Rail for AR-15 Black

GG&G AR15 Under Foregrip Integrated Rail Mount Picatinny Black

There are tons of others too. Look through the Cheaper than dirt web page, and if you don't want to buy from them due to their pricing policies, you will at least have a name and part number to search for.
 
I think if I get one of those foregrips with the built on light and laser a rail down the bottom of my stock hand guard would probably suffice. Thank you guys for all of the info and options!
 
4-rail guards that snap in are a good step and easy to use. But, they are not free float and some care should be taken to not flex your barrel.

Before the craziness just started, I helped a friend put a JP rifle length forearm on his OR along with a low-pro gas block. He went and ordered the JP 3.5T trigger and anti-walk pins directly from JP Enterprises. He upgraded from the UTG guards he originally bought along with the carbine.

I have installed quite a few drop ins for people with different brands of rifles and have yet to flex a barrel. What brand have you dealt with that has a barrel that flexes that easily?
