Matrix Free Float Railed Handguard for M4 / M16 Series Airsoft Rifles (Length: 12.5")

"This product is great. It was very frustrating to install but after I did it had no wobble and the rails lined up straight

"Great rail!! No problem with mine but it did not fit my delta ring piece.... I had to dremel it down but it fits! And it does not have any trademarks that is shown in the picture.

"Doesn’t match height of optics rail on upper assembly of the Matrix sportline M4. It is lower and look pretty stupid. Install was a little tricky as well. Had to adjust it many times to get it to hold outer barrel tight.

"Very Unpleased. I had installed this with another barrel nut because the one that was given was a piece of garbage. The holes in the barrel but were cut so irregularly that it was impossible to keep the part that screw on top of the nut to secure the nut and the rail to the gun. The barrel nuts holes were drilled or pressed so wrong that the metal on the most outer part was so thin I bent it with a screwdriver. I DO NOT RECOMEND IT. The ris is great but for a bogus barrel nut you have to spend like 15 bucks more for a new one and its not even your fault.

"i was excited to get this RIS. But when i went to put it on. it did not fit in my gun. I have an Elite Force M4 CQB, the old one and the threads that connect it to the upper receiver were wrong. idk if it was my gun for some reason having different threads but the weld on the rail were also broken and what should of been 3 pieses were 4.
