"This RIS unit is by far one of the better I have purchased. The C&C aluminum body is not only impact resistant, but looks great as well. Then only thing I found to be wrong with it, is that on some M4's with a one piece barrel and gas tube it does not fit properly under the delta ring. A fix for this problem is to simply tap the unit into place with a rubber mallet and weld it into place. This may sound extreme, but it is the best way to ensure that the RIS will properly stay in place. Otherwise the RIS will become unseated in the delta ring and fall out of place. 3 simple tac welds on both sides of the RIS will ensure a perfect fit, enabling you to attach a foregrip or M203 safely and properly. Once welded on, this thing worked great and looked perfect.

"This is a high quality product that has exceptionally little wobble (at least on the KM4A1 I installed it on). After going through two other RIS' that didn't fit, this is the third time charm that worked, and I am more than convinced that I got my money's worth.

High Quality
No Wobble

Tight Fit
Lack of Cons to constitute an entire list
