Nope, they shouldn't move if installed correctly. You'd better contact the company's tech support to see if they can help you over the phone.

yeah, they shouldn't move at all. Do you have pictures of the rails and how they look on your rifle?

I would buy a name brand product. Buy cheap, buy twice. Not saying the stuff is bad, or it won't work, but you'll want something better.

I'd recommend this for ease of installation and quality although it is a bit pricey..

If you don't mind and know how to remove the front sight post, gas tube, and barrel nut I'd recommend a LaRue, Daniel Defense, or Samson rail system.

There should be no movement at all. I had never heard of the brand you linked to...however, it is possible you do have them installed correctly and they are fine. Perhaps the delta ring is not fully seated? Try pulling on it and twisting it and pushing if forward a little and see if things click into place and thus tighten up for you. I have seen some railed forends that were a miss aligned and the delta ring did not seat down and was resting too high too secure them in place. A little force (not too much or you'll scratch things) and it fell into place and everything was snug.They need to have ZERO play or movement. They are meant to hold zero for a scope or laser sight. If they do not...they are junk and should be replaced.

Midwest Industries is a great option. If you have movement with them, then your upper is messed up...because they are super snug and have zero plat on every upper I have ever installed them on.

$180.00 and they will not move unless your upper is seriously jacked up.

Thanks for the help and feedback guys.

i played around with the delta ring and it looks like the rail system is in place but i still can figure out why it still moves, i might just go with a free float system but before iam gonna have my local gun shop look at it.

Once agian thanks guys for your help and feedback!

They shouldn't move ONLY if they're designed to not move (which means having some means to tighten the rails).

Make sure the slight movement your feeling is the rails. You may have slight movement between your upper and lower. My first AR slightly moved. I thought it was my rail. It was just the upper from the lower.

However you really will be more pleased with a good name brand that is trusted and used by operators. They are better built and more solid.

The UTG rail you linked has been debated thread after thread and it is was think, bulky and heavy. Airsoftish.

that system is a little loose because they'res no tightening device.
If you look at the DD omega, the KAS RAS, they all have some sort of screw or screws that'll tighten the rails. Looking at the one you just bought, they dont have any sort of torque system for keeping the rails firmly in place.

there is no brand name anywhere, nor on the rail system or in the receipt.
i took it to my local gun shop and they said that, it might just be designed to move a little bit. they tryed playing around with it as well. but no luck.

Personally, I really like the KAC M5 rail when it comes to 20" handguards, but I know there are many others of comparable or superior quality out there. Look into LaRue, DD, Troy, Midwest Industries, etc... for starters. Remember, you get what you pay for, so expect to spend a good hunk of dough on your handguards.
