"Pretty good piece of kit. Requires the real steel style delta ring for proper fit. The pieces are definitely rigid and the finish is pretty nice. It is not terribly wobbly when assembled, but I did add some duct tape in the groove where the delta ring teeth go and now it is rock solid. The relatively soft heat shield is riveted to the inside of the bottom half of the hand guard and doesn't seem like it was meant to be removable if you wanted to do that. The heat shield also has grooves that partially grab the inside of the upper half to improve stability. Overall I am pleased and it is great for that classic M4 RIS look at an affordable price. Would recommend it.

"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
