Make sure it is properly seated, and that the delta ring is pushed forward all the way.

It is normal for the lower rail to have play in it.

Quoted: Make sure it is properly seated, and that the delta ring is pushed forward all the way. This. Mine fits very snug. Make sure you tighten down that front clamp on the top rail and then get the bottom rail all the way up inside the top rail. Push "forward" on the delta ring after they're both in there and get it to clamp down properly on both halves. I really like this rail even though its technically "dated." Fits my BCM SOCOM upper perfectly.  |

Out of curisosity.... did your rail come with the steel triangle shaped insert that goes between the two halves into the handguard cap? I ask this because a firend of mine got an RIS that did not have this piece and his was very sloppy as well. Mine is rock solid on the bottom and I do have the insert. There are two springs on the insert that put pressure on the lower section.

There are two springs on the insert that put pressure on the lower section. That insert is for the Rifle M5 RAS and for mounting a M203. Unnecessary if you are not mounting a M203. |

Thanks for the replies guys.
I took off and put on the RIS about 10 times last night, every time, the damn bottom half would rattle. This morning, I got up, and took the RIS off AGAIN, and just studied them. On the TOP portion of the RIS, there's a small 'bolt' with an allen head in it that holds what looks like a small bracket that the Delta ring attaches to, the bracket goes around the gas tube...this little piece was loose. I put some loc-tite on the bolt, snugged it down about a 1/4 turn past 'snug', and then re-installed...the RIS is as solid as a rock now. As for the 'bracket', I don't have that part. Hax |

Hax You have an RAS not an RIS. The RIS does not have that bracket on top. The RAS does have this bracket. The RAS is the newer, better, more solid version of the RIS. |

Glad you got it fixed. Now post pictures. They go here, in the A4 thread, and in the BCM upper thread.
And be quick about it.

I had some trouble getting mine on as well back when I started my A4 build. This link helped me greatly though––––->M5 RAS installation instruction in a PDF.
