    Is anyone using drop in front rails on their AR....any thoughts, comments or concerns?

    I was thinking about going this way instead of attaching permanent rails and wondered if there is any downside. I do like the idea of being able to switch out the rails at will if I want to.

    Anyone carry them locally so I can take a look....?

    If you mean rails that bolt onto the handguards individually, Wholesale Sports (Formally Sportsmans Warehouse) carries "Ergo" rail sections that work well.

    If you mean drop-in quad rails, they work as can be expected. But most of them have some wobble.

    The latter....and yes, I was wondering about wobble factor, is it substantial...enough to cause a problem for a pop out bi pod?

    I was going to use the bolt on rails, but the Colt I have has a double baffle in the hand guard and it's also epoxied into place....!

    No, Vertical Foregrips and Bipods will function just fine on a DI Quad Rail. Tac lights too. Daniel Defense has the "Omega" rail, which drops right in, but uses set screws to make it tight. It's also free floated. Pretty cool design, but a little more expensive.

    But, all in all, Drop In rails are good to go for most things, if you don't mind some wobble in your hand. Just don't put an optic on it!

    I have a YHM 2 piece handguard on 1 of my AR's,works well and allows me to go back to a stock grip if i want to.
    The 2 pc is very tight,and takes some effort to put on,which is a good thing.
    Mine is the one that is almost in the center of the page.

    I have 2 different ones, both quad rail and drop in, both work very well, for grips/lights but as 'wakejoe' says I would not put an optic on it. There is some play in them but no different from my fat M4 handguards.

    If you are looking for carbine length and are down this way and want to slap them on your upper to check them out let me know.

    Thanks for the replies...I think I get it...'no optics', good, check :)

    OK, looks like I know the direction I need to take....

    wayoutwest...I'm headed to South in a couple of weeks, may just swing by your direction then.

    I have the Knights Armament rail on one of my AR's. The top and sides are one piece and rock solid. The bottom has a little slop when you use the leverage from a vertical front grip to rock it back and fourth.

    wakejoe, your a star, the Ergo's are just what I needed. They have a different fitting method which means you can run a hex wrench from the outside fitting the bolt into a plate that (with a little finesses) you can line up with the holes on the inside between the baffle plates.

    Just got it all mounted and it looks great, now I have to see ho wit functions when I hit the range tomorrow.

    Here is a little collage.

    1. The handle/bipod attached
    2. The allen head bolt going through the rail
    3. The inside of the hand guard
      • Their are no holes on th einside bafle of the Colt
      • You can just about make out the little plate that the bolt threads into on the back side.
